Definitions
- the field of the invention relates to process belts and more specifically, to process belts used in manufacturing processes, e.g., the manufacture of pressed board or other paper products.
- process belts are used in the preparation of pulp or materials in sheet or non-woven fabric, such as paper or board, in the Paper or Board Making Industry.
- Such process belts are typically woven wire fabric formed into continuous or endless belts by brazing or welding.
- end sections of such process belts are generally brazed or welded together to form a brazed or welded seam between the end sections of the process belt, thereby introducing a local stiffness at the seam.
- brazing or welding typically degrades the strength and malleability of the wires adjacent the brazed or welded seam due to elevated temperatures. The degradation can result in premature failure of such process belts at or near the brazed or welded seam, which generally requires the process belt to be removed, repaired and reinstalled on the paper process machine or to be replaced with a new process belt.
- FIG. 1 is an illustrative view of a process belt having a seam connecting a first end of the process belt to a second end of the process belt in accordance with principles of the invention
- FIG. 2 is an enlarged illustrative view of the process belt shown in FIG. 1 , which shows the seam in greater detail;

- FIGS. 1-4 show an embodiment of a process belt, generally indicated at 10 , for use in a board processing machine or other paper converting machine ( FIG. 10 ) to process a board stock or other paper product.
- the belt 10 is referred to as a “process belt” herein, but can be used in processing both paper or board, oriented strand board, pressed board or joists, depending on the desired process.
- the process belt 10 comprises a body portion, generally indicated at 12 , separating a first end section 14 and a second end section 16 .
- the first end section 14 and the second end section 16 form ends of the body portion 12 .
- the body portion 12 is only partially shown in FIG. 1 .
- the first end section 14 is operatively coupled to the second end section 16 by a seam, generally indicated at 17 , such that the body portion 12 , the first end section 14 and the second end section 16 are substantially continuous with one another and configured to operatively engage the board processing machine or other paper converting machine, as is further described below.
- the seam 17 can include at least one elongated resilient coupling filament 24 ( FIGS. 2-4 ) to fixedly secure the first and second end sections 14 , 16 to one another.
- FIG. 2 shows the process belt 10 and the seam 17 in greater detail.
- the body portion 12 comprises a first plurality of elongated resilient filaments 20 oriented in a vertical (or first) direction.
- the vertical direction can be referred to as a machine direction and each elongated resilient filament 20 can be referred to as a warp filament, for example.
- the body portion 12 can also include a second plurality of elongated resilient filaments 22 oriented in a horizontal direction (a second direction) transverse to the vertical (or first) direction.
- the horizontal direction can be referred to as a cross machine direction and each elongated resilient filament 22 can be referred to as a shute or weft filament, for example.
- the individual filaments 20 , 22 can be woven together, for example, using a weaving machine, or may be weaved manually, to form the body portion 12 .
- a single beam loom or a double beam loom can be used depending on the type of weave pattern chosen for the belt 10 .
- each vertically extending filament 20 can be woven around each horizontally extending filament 22 .
- a first plurality of looped segments 26 can be attached to the first end section 14 of the process belt 10 , for example, by weaving, bonding or welding.
- each looped segment 26 can include a first end 28 , a second end 30 ( FIG. 3 ) and a looped section 32 extending between the first and second ends 28 , 30 .
- the looped section 32 can be configured to form a coupling filament receiving opening 33 therein ( FIG. 3 ) configured to receive the coupling filament 24 therethrough.
- the first and second ends 28 , 30 can be attached to the first end section 14 of the process belt 10 , for example, by weaving ( FIG. 3 ) or bonding, such as welding or fusing, so that the looped section 32 and the coupling filament receiving opening 33 outwardly extend away from the first end section 14 .
- the weaving can be performed manually or mechanically.
- each looped segment 34 can include a first end 36 , a second end 38 ( FIG. 3 ) and a looped section 40 extending between the first and second ends 34 , 36 .
- the looped section 40 forms a coupling element receiving opening 41 therein (shown in substantial alignment with the coupling element receiving opening 33 shown in FIG. 3 ).
- the first and second ends 34 , 36 are attached to the second end section 16 of the process belt 10 , for example, by weaving ( FIG. 3 ) or bonding such as welding or fusing, so that the looped section 40 outwardly extends away from the second end section 16 .
- the looped segments 26 , 34 may be distinguished from one another with markings, such as being painted different colors, for example.
- the distinguishing markings can help ensure that a sufficient number of looped segments 26 and 34 are attached to respective end portions 14 , 16 of the belt 10 .
- holes may need to be formed in the existing belt 10 .
- Such holes which may be formed with a drill, an awl, a plasma arc cutter or other tool capable of forming a hole in the belt 10 , can allow ends 28 , 30 or ends 34 , 36 of the respective looped segment 26 , 34 to be woven into the belt 10 , as described above, about the horizontally extending filaments 22 .
- Such holes may also be formed by displacing the filaments 20 , 22 to create a space with no need to drill or cut the belt 10 in any manner.
- first and second ends 28 , 30 of the looped segment 26 can be bonded, for example, by welding or fusing, to either the vertically extending filaments 20 or the horizontally extending filaments 22 .
- first end 28 can be bonded or fused to the second end 30 after the looped portion 32 has been formed.
- the first and second ends 34 , 36 of the looped segment 32 can also be bonded or fused to the vertically extending filaments 20 , to the horizontally extending filaments 22 or to one another.
- Each individual vertically extending filament 20 , each horizontally extending filament 22 and the at least one elongated resilient coupling filament 24 can be made from carbon steel, stainless steel or other sufficiently hardened material, for example, into solid filaments as shown in FIG. 4 .
- the filaments 20 , 22 , 24 can have equal or different sized diameters.
- each individual filament 20 , 22 , 24 can include a plurality of filaments braided or twisted together to form a braided or twisted filament.
- Filaments 20 , 22 , 24 can include different twist patterns, for example, a left-handed twist or a right-handed twist, to increase durability of the belt 10 .
- Combinations of solid and braided or twisted filaments can also be used for the filaments 20 , 22 , 24 .
- Each filament 20 , 22 and 24 can be coated, for example, to reduce corrosion and/or abrasion, through a coating process.
- the coating may be a low friction and contaminant resistant protective coating, for example, and may include brass or some other hardening (corrosion and abrasion resistant) material.
- the low friction and contaminant resistant protective coating can be applied by conventional coating techniques, such as dipping or continuously running the filaments through a bath. Alternatively, a batch dipping can be used.
- FIGS. 2-4 show the looped segments 26 , 34 in greater detail.
- the looped sections 32 and 40 can be aligned with one another such that the at least one elongated resilient coupling filament 24 can be received through the openings 33 , 41 ( FIG. 3 ).
- End portions (not shown) of each coupling filament 24 can be bent in a cross machine direction (opposite to the side of the belt 10 , which engages rollers during operation) to help axially position the coupling filament 24 in the horizontal or cross machine direction.
- the looped segments 26 , 34 can be made from a sufficiently flexible material, such as soft stainless steel, or plasticized material, e.g., a plastic, a synthetic, a thermoplastic or a polymer. Other flexible materials can also be used, such as metal wire, sewing wires, cables wire or high tensile wires.
- the sufficiently flexible material can be more flexible and softer than the hardened material used to form the filaments 20 , 22 , 24 .
- the sufficiently flexible material allows for formation of the looped sections 32 , 40 described above and may determine whether respective ends of the looped segments 26 , 32 are weaved, bonded or fused to the belt 10 or bonded or fused to one another.
- a process belt 110 can have a seam 117 formed into a castellated configuration.
- the belt 110 includes a plurality of the body portions 12 , as described above.
- Each body portion 12 has a first set of the elongated resilient filaments (not shown) oriented in a vertical (or first) direction located in a middle portion 121 and respective edge portions 123 , 125 .
- Each body portion 12 also has a second set of the elongated resilient filaments (not shown) oriented in a horizontal (or second) direction.
- the vertically and horizontally extending filaments can be substantially similar in construction and operation as the filaments 20 , 22 , respectively, described above.
- Adjacent body portions 12 can be operatively connected to one another by the seam 117 to form a continuous belt 110 .
- the seam 117 is substantially similar in configuration and operation as the seam 17 , and includes the looped segments 26 , 32 . Because the edge portions 123 , 125 do not operatively connect adjacent body portions 12 together at the same plane as the middle portion 121 , the seam 117 can be referred to as castellated.
- one or more (e.g., three) coupling filaments 24 can be provided to cooperate with the looped segments 26 , 32 to one another.
- the middle portion 121 of one body portion 12 can be operatively connected to a corresponding middle portion of another body portion 12 and each edge portion 123 , 125 of the one body portion 12 can be operatively connected to corresponding edge portions 123 , 125 of the other body portion 12 .
- the middle portion 121 and edge portions 123 , 125 of one body portion 12 substantially act as a first end section 14 and the middle portion 121 and edge portions 123 , 125 of an adjacent body portion 12 substantially act as a second end section 16 .
- the middle portion 121 or the edge portions 123 , 125 can include equal or different numbers of individual filaments 20 , 22 of equal or different diameters.
- Each edge portion 123 , 125 may extend about 4-8 inches in width in the cross machine direction of the belt 110 and about 6-18 inches in length in the machine direction of the belt 110 .
- Other numbers of filaments and configurations are possible for each portion 121 , 123 , 125 and the number and configuration of each group may differ from portion to portion of the different body portions 12 .
- FIG. 5 shows three castellated seams 117 , more or less seams 117 can be used in the belt 110 .
- the castellated seam 117 allows for independent replacement of a particular body portion 12 , without having to replace the entire belt 110 .
- the castellated seam 117 also can reduce localized stress of the belt 110 during a board processing machine or other paper converting machine operation, which can increase the life of the belt 110 . For example, if one body portion 12 becomes worn or damaged after repeated use, the body portion 12 could be replaced without having to replace the entire belt 110 .
- the seam 117 can be used to replace the seam 17 shown in FIG. 1 .
- the castellated seam 117 allows for independent replacement of a particular portion of the seam 117 , without having to replace the entire seam. For example, if one edge portion 123 or 125 would become worn or damaged after repeated use, the edge portion 123 or 125 could be replaced leaving the middle portion 121 and the other edge portion unrepaired/unreplaced.
- the coupling filament 24 can form a continuous seam between the end sections 14 , 16 so that the belt 10 , 110 can be continuous or endless.
- more than one coupling filament 24 can be used to form the continuous seam between the end sections 14 , 16 , as described above, depending on the process.
- FIGS. 6-9 illustrate alternative ways of attaching first and second ends 28 , 30 and 34 , 36 of looped segments 26 , 32 to a respective end section 14 , 16 of a process belt.
- FIG. 6 shows a portion of a seam 217 , which is variation of the seam 17 , attached to one end section 14 of a process belt 210 .
- the belt 210 is of the woven type with a plurality of vertically extending filaments 220 woven about a plurality of horizontally extending filaments 222 . Different weave patterns or alternative configurations of the belt 210 could also be used.
- the seam 217 includes looped segments 226 , 232 , only looped segment 226 is shown in FIG. 6 . Since looped segments 226 , 232 are substantially similar in construction and operation to looped segments 26 , 32 , the description of looped segment 226 will suffice for looped segment 232 .
- One end 228 of the looped segment 226 is attached to the end section 14 of the belt 210 , at a first horizontally extending filament 222 .
- the opposite end 230 of the looped segment 226 is attached to the end section 14 of the belt 210 , at a different horizontally extending filament 222 as the end 228 .
- stress can be distributed and strain can be reduced on the seam 217 and the belt 210 .
- adjacent looped segments 226 can have respective ends 230 attached to different horizontally extending filaments 222 . In this manner, adjacent ends 230 of the looped segments 226 are staggered so that every other end 230 is attached to the same horizontally extending filament 222 .

- the ends 228 , 230 can extend through holes formed between adjacent filaments 220 , 222 and can be bonded together, for example.
- the ends 228 , 230 need not be attached to the belt 210 , but rather the attachment of the ends 228 , 230 to the belt 210 can be effected by the engagement of the ends 228 , 230 with the filaments 220 , 222 .
- the ends 228 , 230 can be fixedly secured to either the belt 210 , the filaments 220 , the filaments 222 or to one another.
- FIGS. 7-8 show a seam 317 , which is variation of the seam 17 , which operatively couples end sections 314 , 316 of a process belt 310 .
- the belt 310 is of the woven type with a plurality of vertically extending filaments 320 woven about a plurality of horizontally extending filaments 322 . Different weave patterns or alternative configurations of the belt 310 could also be used.
- FIG. 8 shows looped segments 326 , 332 of the seam 317 in greater detail, but only a portion of the looped segment 326 is shown.

- Each looped segment 332 includes an end portion 334 , a connecting portion 335 that connects one end of the end portion 334 to one end of an opposite end portion 336 and a connecting portion 337 that connects another one end of the end portion 336 to the other end of the end portion 334 .
- the end portion 334 is formed to have a generally arcuate configuration to receive a coupling filament 24 therethrough.
- the end portion 334 receives a coupling filament 24 in a similar manner as described above with respect to coupling filament receiving opening 41 , for example.
- the connecting portion 335 extends from the end portion 334 over a plurality of horizontally extending filaments 322 before extending below a plurality of horizontally extending filaments 322 away the coupling filament 24 to connect to one end of the end portion 336 .
- the end portion 336 is formed to have a generally arcuate configuration to contact a selected horizontally extending filament 322 .
- the connecting portion 337 extends from the end portion 336 over a plurality of horizontally extending filaments 322 before extending below a plurality of horizontally extending filaments 322 away the coupling filament 24 to connect to one end of the end portion 334 .

- looped segments such as looped segments 26 , 32 shown in FIG. 1 , for example, can be attached to the belt 410 . Ends of the looped segments can be woven about the plurality of horizontally extending filaments 22 to attach the looped segments to the belt 410 .
- the removal of some vertically extending filaments 20 can eliminate the need to form holes in the belt 410 prior to attachment of the looped segments.
- the vertically extending filaments 22 are grouped in groups of five filaments.
- every third and fifth vertically extending filament 22 (as shown left to right in FIG. 9 ) is removed from the belt 410 , thus leaving the first, second and fourth vertically extending filaments 22 to form sufficient support in the machine direction for the belt 410 .
- Other configurations are possible and can be used as well.
- each group can include more or less filaments, each group can include equal or different numbers of filaments or different filaments from each group can be removed.

Description
- This application claims the benefit of U.S. Provisional Patent Application No. 60/341,873, “Schmitt Seam,” Maguire et al., filed Dec. 21, 2001, the contents of which are incorporated herein by reference in their entirety.
- The field of the invention relates to process belts and more specifically, to process belts used in manufacturing processes, e.g., the manufacture of pressed board or other paper products.
- Generally, process belts are used in the preparation of pulp or materials in sheet or non-woven fabric, such as paper or board, in the Paper or Board Making Industry. Such process belts are typically woven wire fabric formed into continuous or endless belts by brazing or welding. For example, end sections of such process belts are generally brazed or welded together to form a brazed or welded seam between the end sections of the process belt, thereby introducing a local stiffness at the seam.
- However, brazing or welding typically degrades the strength and malleability of the wires adjacent the brazed or welded seam due to elevated temperatures. The degradation can result in premature failure of such process belts at or near the brazed or welded seam, which generally requires the process belt to be removed, repaired and reinstalled on the paper process machine or to be replaced with a new process belt.
- The accompanying drawings, which are incorporated in and constitute a part of the specification, of embodiments of the invention, together with the general description given above and the detailed description of the embodiments given below, serve to explain the principles of the invention wherein:

FIGS. 1-4 show an embodiment of a process belt, generally indicated at 10, for use in a board processing machine or other paper converting machine (FIG. 10 ) to process a board stock or other paper product. Thebelt 10 is referred to as a “process belt” herein, but can be used in processing both paper or board, oriented strand board, pressed board or joists, depending on the desired process. Theprocess belt 10 comprises a body portion, generally indicated at 12, separating afirst end section 14 and asecond end section 16. Thefirst end section 14 and thesecond end section 16 form ends of thebody portion 12. Thebody portion 12 is only partially shown inFIG. 1 . Thefirst end section 14 is operatively coupled to thesecond end section 16 by a seam, generally indicated at 17, such that thebody portion 12, thefirst end section 14 and thesecond end section 16 are substantially continuous with one another and configured to operatively engage the board processing machine or other paper converting machine, as is further described below. Theseam 17 can include at least one elongated resilient coupling filament 24 (FIGS. 2-4 ) to fixedly secure the first and 14, 16 to one another.second end sections -
FIG. 2 shows theprocess belt 10 and theseam 17 in greater detail. As illustrated, thebody portion 12 comprises a first plurality of elongatedresilient filaments 20 oriented in a vertical (or first) direction. The vertical direction can be referred to as a machine direction and each elongatedresilient filament 20 can be referred to as a warp filament, for example. Thebody portion 12 can also include a second plurality of elongatedresilient filaments 22 oriented in a horizontal direction (a second direction) transverse to the vertical (or first) direction. The horizontal direction can be referred to as a cross machine direction and each elongatedresilient filament 22 can be referred to as a shute or weft filament, for example. - The
20, 22 can be woven together, for example, using a weaving machine, or may be weaved manually, to form theindividual filaments body portion 12. Alternatively, a single beam loom or a double beam loom can be used depending on the type of weave pattern chosen for thebelt 10. In the particular weave pattern of theseam 17 shown inFIG. 3 , for example, each vertically extendingfilament 20 can be woven around each horizontally extendingfilament 22. - A first plurality of looped
segments 26 can be attached to thefirst end section 14 of theprocess belt 10, for example, by weaving, bonding or welding. For example, each loopedsegment 26 can include afirst end 28, a second end 30 (FIG. 3 ) and a loopedsection 32 extending between the first and 28, 30. The loopedsecond ends section 32 can be configured to form a coupling filament receiving opening 33 therein (FIG. 3 ) configured to receive thecoupling filament 24 therethrough. The first and 28, 30 can be attached to thesecond ends first end section 14 of theprocess belt 10, for example, by weaving (FIG. 3 ) or bonding, such as welding or fusing, so that the loopedsection 32 and the coupling filament receiving opening 33 outwardly extend away from thefirst end section 14. The weaving can be performed manually or mechanically. - Similarly, a second plurality of looped
segments 34 are attached to thesecond end section 16 of theprocess belt 10, for example, by weaving or bonding such as welding or fusing. For example, each loopedsegment 34 can include afirst end 36, a second end 38 (FIG. 3 ) and a loopedsection 40 extending between the first and 34, 36. The loopedsecond ends section 40 forms a coupling element receiving opening 41 therein (shown in substantial alignment with the couplingelement receiving opening 33 shown inFIG. 3 ). The first and 34, 36 are attached to thesecond ends second end section 16 of theprocess belt 10, for example, by weaving (FIG. 3 ) or bonding such as welding or fusing, so that the loopedsection 40 outwardly extends away from thesecond end section 16. - During manual weaving of the looped
26, 34, the loopedsegments 26, 34 may be distinguished from one another with markings, such as being painted different colors, for example. The distinguishing markings can help ensure that a sufficient number of loopedsegments 26 and 34 are attached tosegments 14, 16 of therespective end portions belt 10. - To effect weaving of the looped
26, 34 intosegments 14, 16 of therespective end sections belt 10, holes may need to be formed in the existingbelt 10. Such holes, which may be formed with a drill, an awl, a plasma arc cutter or other tool capable of forming a hole in thebelt 10, can allow 28, 30 orends 34, 36 of the respective loopedends 26, 34 to be woven into thesegment belt 10, as described above, about the horizontally extendingfilaments 22. Such holes may also be formed by displacing the 20, 22 to create a space with no need to drill or cut thefilaments belt 10 in any manner. - Alternatively, in another embodiment, one or both of the first and
28, 30 of the loopedsecond ends segment 26 can be bonded, for example, by welding or fusing, to either the vertically extendingfilaments 20 or the horizontally extendingfilaments 22. Also, thefirst end 28 can be bonded or fused to thesecond end 30 after the loopedportion 32 has been formed. The first and 34, 36 of the loopedsecond ends segment 32 can also be bonded or fused to the vertically extendingfilaments 20, to the horizontally extendingfilaments 22 or to one another. - Each individual vertically extending
filament 20, each horizontally extendingfilament 22 and the at least one elongatedresilient coupling filament 24 can be made from carbon steel, stainless steel or other sufficiently hardened material, for example, into solid filaments as shown inFIG. 4 . The 20, 22, 24 can have equal or different sized diameters. Alternatively, eachfilaments 20, 22, 24 can include a plurality of filaments braided or twisted together to form a braided or twisted filament.individual filament 20, 22, 24 can include different twist patterns, for example, a left-handed twist or a right-handed twist, to increase durability of theFilaments belt 10. Combinations of solid and braided or twisted filaments can also be used for the 20, 22, 24.filaments - Each
20, 22 and 24 can be coated, for example, to reduce corrosion and/or abrasion, through a coating process. The coating may be a low friction and contaminant resistant protective coating, for example, and may include brass or some other hardening (corrosion and abrasion resistant) material. The low friction and contaminant resistant protective coating can be applied by conventional coating techniques, such as dipping or continuously running the filaments through a bath. Alternatively, a batch dipping can be used.filament -
FIGS. 2-4 show the looped 26, 34 in greater detail. As illustrated, the loopedsegments 32 and 40 can be aligned with one another such that the at least one elongatedsections resilient coupling filament 24 can be received through theopenings 33, 41 (FIG. 3 ). End portions (not shown) of eachcoupling filament 24 can be bent in a cross machine direction (opposite to the side of thebelt 10, which engages rollers during operation) to help axially position thecoupling filament 24 in the horizontal or cross machine direction. - The looped
26, 34 can be made from a sufficiently flexible material, such as soft stainless steel, or plasticized material, e.g., a plastic, a synthetic, a thermoplastic or a polymer. Other flexible materials can also be used, such as metal wire, sewing wires, cables wire or high tensile wires. The sufficiently flexible material can be more flexible and softer than the hardened material used to form thesegments 20, 22, 24. The sufficiently flexible material allows for formation of the loopedfilaments 32, 40 described above and may determine whether respective ends of the loopedsections 26, 32 are weaved, bonded or fused to thesegments belt 10 or bonded or fused to one another. - Alternatively, as shown in
FIG. 5 , aprocess belt 110 can have aseam 117 formed into a castellated configuration. For example, thebelt 110 includes a plurality of thebody portions 12, as described above. Eachbody portion 12 has a first set of the elongated resilient filaments (not shown) oriented in a vertical (or first) direction located in amiddle portion 121 and 123, 125. Eachrespective edge portions body portion 12 also has a second set of the elongated resilient filaments (not shown) oriented in a horizontal (or second) direction. The vertically and horizontally extending filaments can be substantially similar in construction and operation as the 20, 22, respectively, described above.filaments -
Adjacent body portions 12 can be operatively connected to one another by theseam 117 to form acontinuous belt 110. Theseam 117 is substantially similar in configuration and operation as theseam 17, and includes the looped 26, 32. Because thesegments 123, 125 do not operatively connectedge portions adjacent body portions 12 together at the same plane as themiddle portion 121, theseam 117 can be referred to as castellated. - In this embodiment, one or more (e.g., three)
coupling filaments 24 can be provided to cooperate with the looped 26, 32 to one another. For example, thesegments middle portion 121 of onebody portion 12 can be operatively connected to a corresponding middle portion of anotherbody portion 12 and each 123, 125 of the oneedge portion body portion 12 can be operatively connected to corresponding 123, 125 of theedge portions other body portion 12. In this regard, themiddle portion 121 and 123, 125 of oneedge portions body portion 12 substantially act as afirst end section 14 and themiddle portion 121 and 123, 125 of anedge portions adjacent body portion 12 substantially act as asecond end section 16. - The
middle portion 121 or the 123, 125 can include equal or different numbers ofedge portions 20, 22 of equal or different diameters. Eachindividual filaments 123, 125 may extend about 4-8 inches in width in the cross machine direction of theedge portion belt 110 and about 6-18 inches in length in the machine direction of thebelt 110. Other numbers of filaments and configurations are possible for each 121, 123, 125 and the number and configuration of each group may differ from portion to portion of theportion different body portions 12. - Although
FIG. 5 shows threecastellated seams 117, more orless seams 117 can be used in thebelt 110. Thecastellated seam 117 allows for independent replacement of aparticular body portion 12, without having to replace theentire belt 110. Thecastellated seam 117 also can reduce localized stress of thebelt 110 during a board processing machine or other paper converting machine operation, which can increase the life of thebelt 110. For example, if onebody portion 12 becomes worn or damaged after repeated use, thebody portion 12 could be replaced without having to replace theentire belt 110. - The
seam 117 can be used to replace theseam 17 shown inFIG. 1 . Thecastellated seam 117 allows for independent replacement of a particular portion of theseam 117, without having to replace the entire seam. For example, if one 123 or 125 would become worn or damaged after repeated use, theedge portion 123 or 125 could be replaced leaving theedge portion middle portion 121 and the other edge portion unrepaired/unreplaced. - In either
17 or 117, theseam coupling filament 24 can form a continuous seam between the 14, 16 so that theend sections 10, 110 can be continuous or endless. To help increase the strength of the continuous seam, more than onebelt coupling filament 24 can be used to form the continuous seam between the 14, 16, as described above, depending on the process.end sections -
17, 117 have been described above as having loopedSeams 26 and 32 that cooperate with one orsegments more coupling filaments 24.FIGS. 6-9 illustrate alternative ways of attaching first and second ends 28, 30 and 34, 36 of looped 26, 32 to asegments 14, 16 of a process belt.respective end section - For example,
FIG. 6 shows a portion of aseam 217, which is variation of theseam 17, attached to oneend section 14 of aprocess belt 210. Thebelt 210 is of the woven type with a plurality of vertically extendingfilaments 220 woven about a plurality of horizontally extendingfilaments 222. Different weave patterns or alternative configurations of thebelt 210 could also be used. - Although the
seam 217 includes loopedsegments 226, 232, only loopedsegment 226 is shown inFIG. 6 . Since loopedsegments 226, 232 are substantially similar in construction and operation to looped 26, 32, the description of loopedsegments segment 226 will suffice for looped segment 232. - One
end 228 of the loopedsegment 226 is attached to theend section 14 of thebelt 210, at a first horizontally extendingfilament 222. Theopposite end 230 of the loopedsegment 226 is attached to theend section 14 of thebelt 210, at a different horizontally extendingfilament 222 as theend 228. By attaching the 228, 230 to different horizontally extendingends filaments 222, stress can be distributed and strain can be reduced on theseam 217 and thebelt 210. To further distribute stress and reduce strain, adjacent loopedsegments 226 can haverespective ends 230 attached to different horizontally extendingfilaments 222. In this manner, adjacent ends 230 of the loopedsegments 226 are staggered so that everyother end 230 is attached to the same horizontally extendingfilament 222. - Alternatively, adjacent groups of looped
segments 226 can haverespective ends 230 contacted with different horizontally extendingfilaments 222, with looped segments of each group having anend 230 contacted with the same horizontally extendingfilament 222. - In this embodiment, ends 228, 230 can be attached to one or more horizontally extending
filaments 222 by weaving one or both of the 228, 230 about one or more horizontally extendingends filaments 222 or by bonding, such as welding or fusing, to one or more horizontally extendingfilaments 222. Alternatively, the 228, 230 can extend through holes formed betweenends 220, 222 and can be bonded together, for example. In this configuration, theadjacent filaments 228, 230 need not be attached to theends belt 210, but rather the attachment of the 228, 230 to theends belt 210 can be effected by the engagement of the 228, 230 with theends 220, 222. For example, thefilaments 228, 230 can be fixedly secured to either theends belt 210, thefilaments 220, thefilaments 222 or to one another. -
FIGS. 7-8 show aseam 317, which is variation of theseam 17, which operatively couplesend sections 314, 316 of aprocess belt 310. Thebelt 310 is of the woven type with a plurality of vertically extendingfilaments 320 woven about a plurality of horizontally extendingfilaments 322. Different weave patterns or alternative configurations of thebelt 310 could also be used. -
FIG. 8 shows looped 326, 332 of thesegments seam 317 in greater detail, but only a portion of the loopedsegment 326 is shown. Since looped 326, 332 are substantially similar in construction and operation to loopedsegments 26, 32 described above, the description of loopedsegments segment 332 will suffice for loopedsegment 326. - Each looped
segment 332 has ends thereof bonded, fused or connected together so that each loopedsegment 332 substantially forms a ∞ shape. Each loopedsegment 332 includes anend portion 334, a connectingportion 335 that connects one end of theend portion 334 to one end of anopposite end portion 336 and a connectingportion 337 that connects another one end of theend portion 336 to the other end of theend portion 334. - In this embodiment, the
end portion 334 is formed to have a generally arcuate configuration to receive acoupling filament 24 therethrough. Theend portion 334 receives acoupling filament 24 in a similar manner as described above with respect to couplingfilament receiving opening 41, for example. The connectingportion 335 extends from theend portion 334 over a plurality of horizontally extendingfilaments 322 before extending below a plurality of horizontally extendingfilaments 322 away thecoupling filament 24 to connect to one end of theend portion 336. Theend portion 336 is formed to have a generally arcuate configuration to contact a selected horizontally extendingfilament 322. The connectingportion 337 extends from theend portion 336 over a plurality of horizontally extendingfilaments 322 before extending below a plurality of horizontally extendingfilaments 322 away thecoupling filament 24 to connect to one end of theend portion 334. - When the connecting
portion 335 extends from one end theend portion 334 over a plurality of horizontally extendingfilaments 322, the connectingportion 337 extends below the same plurality of horizontally extendingfilaments 322 to connect to another end of theend portion 334. Similarly, when the connectingportion 335 extends below a plurality of horizontally extendingfilaments 322, the connectingportion 337 extends from one end of theend portion 336 above the same plurality of horizontally extendingfilaments 322. Because of this intersection, each loopedsegment 332 can be referred to as being in a ∞ shape. - To distribute stress and reduce strain on the
belt 310, adjacent loopedsegments 332 can haverespective end portions 336 contacted with different horizontally extendingfilaments 322, as shown inFIG. 8 . Alternatively, adjacent groups of loopedsegments 332 can haverespective end portions 336 contacted with different horizontally extendingfilaments 322, with looped segments of each group having anend portion 336 contacted with the same horizontally extendingfilament 322. -
FIG. 9 shows abelt 410, which is substantially similar in construction and operation as thebelt 10 shown inFIG. 1 , but with certain vertically extendingfilaments 20 removed from thebelt 410. Some vertically extendingfilaments 20 can be removed from thebelt 410 to allow easier formation of theseam 17, for example. With some vertically extendingfilaments 20 removed, looped segments, such as looped 26, 32 shown insegments FIG. 1 , for example, can be attached to thebelt 410. Ends of the looped segments can be woven about the plurality of horizontally extendingfilaments 22 to attach the looped segments to thebelt 410. The removal of some vertically extendingfilaments 20 can eliminate the need to form holes in thebelt 410 prior to attachment of the looped segments. - As illustrated, the vertically extending
filaments 22 are grouped in groups of five filaments. In eachgroup 412, every third and fifth vertically extending filament 22 (as shown left to right inFIG. 9 ) is removed from thebelt 410, thus leaving the first, second and fourth vertically extendingfilaments 22 to form sufficient support in the machine direction for thebelt 410. Other configurations are possible and can be used as well. For example, each group can include more or less filaments, each group can include equal or different numbers of filaments or different filaments from each group can be removed. -
FIG. 10 shows theprocess belt 10 operatively engaged with a processing machine, which can be a board processing machine or other paper converting machine, generally indicated at 500, for example in a paper production facility. In general, theboard processing machine 500 includes a plurality of belts suspended from a plurality of rollers, some of which can be driven, to effect transport of paper or board material or stock from one point in the production facility to another. - As illustrated in this embodiment, the
board processing machine 500 is a pressed board machine configured to process press board. In this embodiment, theboard processing machine 500 can include theprocess belt 10 trained around a series of processing rolls 502 and anotherprocess belt 504 which together pull a board product or other paper product (not shown) therethrough. The board product can include two or more board layers, which are to be joined to one another by a suitable adhesive in theboard processing machine 500. The board layers are brought together at one end of theboard processing machine 500 and are pulled across a hot roll 506 (or a series of hot plates) by thebelts 10, 102 to dry and/or to cure the adhesive which bonds the board layers together. Abelt 508 operatively associated with thehot roll 506 can carry the finished board product to another part of the paper production facility. - The
board processing machine 500 is not limited to pressed board machines, but can be any processing machine capable of exerting high machine speeds or high stresses onto the belt and requiring a high number of operational cycles. For example, theboard processing machine 500 may be able to process oriented strand boards or joists in addition to pressed board. -
FIG. 11 shows a flow chart illustrating a method of manufacturing a process belt for use in a board processing machine to process a board stock or other paper product. The method starts at 600. At 602, a body portion of the process belt is formed to have a first end section and a second end section. The body portion can be formed in many ways, one of which includes positioning a first plurality of elongated resilient filaments in a first direction and positioning a second plurality of elongated resilient filaments in a second direction transverse to the first direction. The first plurality of elongated resilient filaments and the second plurality of elongated resilient filaments can be woven together in a conventional manner, for example, manually or mechanically, in any known weave pattern or may be bonded or fused together. - At 604, at least one first looped segment is attached to the first end section of the process belt and at least one second looped segment is attached to the second end section of the process belt. The first and second looped segments extend between the first end section and the second end section of the process belt and can be aligned to receive at least one coupling filament therethrough. The first and second looped segments can be attached to the first and second end sections of the process belt in various ways, for example, by weaving or bonding as described above with respect to
FIGS. 1-9 . Other ways of attaching the first and second looped segments to the respective first and second end sections of the process belt can be used as well. - At 606, at least one coupling filament operatively connects the first end section to the second end section. For example, the coupling filament can be inserted, for example, manually or mechanically, through the first and second looped segments to form a continuous seam between the first end section, the second end section and the body portion. That way, the first end section, the second end section and the body portion are substantially continuous with respect to one another. End portions of the coupling filament can be bent over a number of the first and second looped segments to fixedly secure the coupling filament within the first and second looped segments. At 608, the method ends.
- While the present invention has been particularly shown and described with reference to the preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details can be made therein without departing from the spirit and scope of the invention.
