Description

Pre-cut adhesive coated tapes and dispensers for heavy workloads {HEAVY DUTY PRE-CUT ADHESIVE COATED TAPES AND DISPENSER}

This technique provides a sufficient structure for an adhesive coating sheet suitable for connecting or bonding one side to another side. Tapes from the # 810 MAGIC trademark clear tape, available from 3M, St. Paul, Minn., Are widely used for a variety of purposes and are commonly used in US Pat. No. 4,928,864 and US Patent No. 116,599. Dispensed from a tape roll on a roll type dispenser such as the dispenser disclosed in the call. Such tape rolls must be cut by hand by cutting means located in the dispenser. It is difficult for the user to cut the adhesive coated tape from the roll into a precise and uniform length by hand because it is difficult to accurately measure the length each time. Such a combination of tape and dispenser is not suitable when the adhesive coated tape must be dispensed quickly and efficiently with accurate and uniform precut length.

South African patent application ZA903889 discloses a separate strip of adhesive coated tape that is mounted to a backing tape. The backing tape, on which the individual strips are attached, is wound and put into the dispenser. Individual tape strips of predetermined length can be easily removed by pulling the backing tape from the dispenser and peeling the tape strip from the dispenser. However, such a solution causes a large amount of backing tape to be consumed and it is also difficult to remove the tape strips by hand.

British Patent No. 2181992 discloses a block overlaid with a plurality of individual adhesive tape strips, wherein the edge area of each adhesive tape strip is provided with adhesive so that the individual tape strips can be easily lifted and removed one by one from the block. Not covered. Edges not covered with adhesive should be removed after removing the tape strip from the block, which is cumbersome. In another embodiment, a non-adhesive element is provided to cover at least the edge region of the adhesive layer. This is also a nuisance and requires the use of two hands, which makes it impossible to attach tapes quickly, such as gift wrap.

Similarly, US Pat. No. 5,153,043 discloses a roll of adhesive tape having a plurality of cuts extending parallel to the longitudinal axis of the roll and allowing the tape to be divided into a plurality of tape strips cut laterally. A portion of the tape, and thus each individual tape, has an adhesive free area adjacent one edge to serve as a leading edge that facilitates removal of the tape strip. This patent also does not provide for quick and easy dispensing of individual tape strips. Moreover, the individual tape strips vary in width throughout the roll, with the tape strips near the core of the roll having a minimum width.

It is also known to dispense transparent tape from pads of tape strips as described in US Pat. No. 4,650,706. U. S. Patent No. 4,650, 706 discloses a tape strip pad in which the length of the tape tab formed at one end of each of the tape strips extending from one end to the opposite end increases gradually from one side of the pad to the other. The U.S. Patent No. 4,650,706 describes that a tape strip with the longest length of the tape tab is separated by holding the tape tab and peeling the strip away from the pad, without subsequent stripping. Therefore, a person who needs a sheet must peel off the sheet by separating the upper sheet from the remaining sheets of the stack by hand, especially when the sheet is to be removed by one hand. Such laminates are not suitable when the user must use both hands for tasks other than dispensing tape, such as gift wrapping.

U. S. Patent No. 4,895, 746 discloses a stack of adhesive coated sheets, such as labels, comprising release means and attachment means that provide a means for easily detaching the top sheet in the stack of sheets. have. U. S. Patent No. 4,895, 746 does not disclose the placement of the release means to fit the alternating opposing edges of the sheets in the stack. Thus, like the tape strip disclosed in U.S. Patent No. 4,650,706, a person in need of a sheet may separate the edge of the upper sheet with his hand and remove the sheet from the rest of the stack, especially if the sheet is to be removed by one hand. Peel off the sheet. U. S. Patent No. 4,895, 746 does not disclose a container for an adhesive coated sheet suitable for wrapping and protecting the sheet.

US Pat. No. 5,401,547, US Pat. No. 5,086,946 and US Pat. No. 5,518,144 are laminates of precut adhesive coated sheets having release means and attachment means that alternate between both ends through the laminate. Is disclosed. These patents also disclose dispensers for easy dispensing of individual sheets. Thus, individual adhesive sheets can be easily dispensed by hand one by one from the laminate. However, the number of sheets in such a laminate is generally limited, because the number of sheets of the laminate is such that the gap between the distribution window of the distributor and the laminate becomes too large when the ends of the laminate are once approached. Because. This makes it difficult to separate the last sheet from the stack. Accordingly, the laminate of adhesive coated sheets in these patents is somewhat inadequate for use by many users who wish to be able to easily and conveniently use multiple adhesive coated sheets.

The present invention relates to a "pre-cut adhesive coated sheet" for joining one side to another and a dispenser particularly suitable for dispensing such multiple sheets.

Detachably adhered to each other to thereby detachably adhere to each other to form a laminate; The sheets may also have the adhesive layer 2, 2A, the surface of the adjacent sheet in the laminate to which the adhesive layer is detachably attached so that the surface of the adjacent sheet can be easily separated along the first end portion 15. First release means providing a first adhesion level along the first end portion 15 of each sheet adjacent to the first end 19 between 2B), and the surface of the adjacent sheet in the laminate; A second release means for providing a second adhesion level along the second end portion 17 of each of the sheets adjacent to the second end 20 between the adhesive layers 2, 2A, 2B; The second adhesive planes 9, 9A, 9B provide a release force greater than the release force that occurs along the first end portion 15, while peeling the sheet from the stack along the second end portion 17. A stack set 70 of adhesive coated sheets is provided which firmly attaches the sheet to adjacent sheets in the stack while separating the sheet along the first end portion 15.

In another embodiment, the present invention provides a dispenser for tape flags and / or page markers such as those sold by 3M Corporation.

In addition, the present invention is a dispenser for distributing a sheet from a sheet stack, which is a stack coming out of a stack of stacks of adhesive coated sheets, to which each stack is attached to a substrate, the walls defining the shape of the dispenser, and the sheet as a stack. Dispensing means comprising openings 42, 82, 92, 126, 132, 142 in one wall passing when dispensed from, and conveying means for causing each stack of the laminate set of adhesive coated sheets to be conveyed under the opening of the dispensing means. There is also provided a distributor comprising (49, 89, 99, 129, 135, 145).

The present invention also provides a dispenser for dispensing a sheet from a sheet laminate, which is a laminate coming out of a laminate set of adhesive coated sheets, comprising walls defining a shape of the dispenser and a cavity for receiving a laminate set of adhesive coated sheets ( adhesive coating sheet as dispensing means 159 including a cavity, a wall 153 having an opening 156 which allows access to the cavity, and a window 152 which passes when the sheet is dispensed from the stack. There is also provided a dispenser comprising transferable dispensing means 159 such that each laminate of the set of laminates can come under a window 152 which is this dispensing means.

The laminate set of dispenser and adhesive coating sheet of the present invention enables the adhesive coating tape to be dispensed quickly and efficiently with a uniform precut length. In addition, the laminate set of the dispenser and adhesive coating sheet of the present invention is particularly suitable for users of heavy rain where there is a need to use a large amount of pre-cut adhesive coating tape without consuming much time in filling the dispenser. The dispenser of the present invention only needs to be filled less frequently than conventional dispensers, and is also easy to fill, making it easier, faster and more reliable to use a larger amount of precut adhesive coated tape than with conventional systems. . In addition, each pre-cut adhesive coating tape is entirely coated with an adhesive, thereby eliminating the need to remove portions that do not contain adhesive as in the prior art.

The present invention provides a laminate set of precut sheets coated with an adhesive. The laminate is typically attached to a rigid or flexible substrate to form a continuous series of laminates. As used herein, the term "flexible substrate" refers to a substrate that can be easily and repeatedly bent without damaging the substrate. Examples of flexible substrates are plastic films, lightweight cardboard and paper. As used herein, "rigid substrate" means a substrate that is not easily bent without damaging the substrate. Examples of rigid substrates are rigid plastic bodies, wood, or thick metals. When the substrate is a rigid substrate, the substrate is preferably substantially non-planar. In one example, the rigid substrate may consist of an arcuate or cylindrical substrate. The laminate is attached to the substrate such that the laminate does not normally deviate from the substrate while each of the precut sheets is dispensed from the laminate. In the context of the present invention, the substrate may also include a combination of substrates. For example, each laminate is attached to a backing sheet having substantially the same dimensions as the laminate, and these laminates are then for example by an adhesive strip that crosslinks the backing sheets of two neighboring laminates to each other. Are connected to each other. In such a case, the substrate comprises a backing sheet of each laminate and an adhesive strip connecting the laminates to each other so that a laminate set of adhesive coated sheets can be formed.

Since flexible substrates can be used in all of the various dispensers of the present invention, it is preferred to use flexible substrates in connection with the present invention. When the laminate set of adhesive coated sheets is used in a dispenser comprising a transportable carrier, the laminate set of adhesive coated sheets preferably includes means for firmly attaching the laminate set to the transportable carrier. According to one embodiment, the substrate is provided with attachment means on the side of the substrate opposite to the side receiving the stack of adhesive coated sheets. In one example, a repositionable adhesive may be provided on the side of the substrate opposite the side to which the laminate is attached. Instead of the repositionable adhesive, other attachment means may be used, such as hook and loop attachments under the trade name SCOTCH, available commercially from 3M, or connecting fasteners, also available from 3M. . In addition, the surface of the transferable carrier is provided with a cloth or nonwoven surface, and on the substrate side of the laminate set of the adhesive coated sheet opposite to the side to which the laminate is attached, the trade name SCOTCH available from 3M Corporation. A fabric cubicle grip is provided. According to an alternative embodiment, a leading edge and / or a distal edge without an adhesive coated sheet stack is provided on the stack set of adhesive coated sheets, such that the stack set has one or more leading and / or end edges on the carrier. It is firmly attached to the transportable carrier by inserting it into the slot. As another embodiment that can be used with a transportable carrier in the form of a rotating wheel or shim to securely attach a set of stacks of adhesive coated sheets to a transportable carrier, the stack of stacks of adhesive coated sheets can be used as a belt. The belt has a diameter large enough to allow the stack of adhesive coated sheets to slide over the transportable carrier so as to be able to mount the stack of stacks thereon and also to allow the transportable carrier to move, i.e., rotate. It has a diameter small enough to allow the set of stacks to slide against the transportable carrier. As a variant of this embodiment, the belt is provided with a diameter smaller than the diameter of the transportable carrier, and the substrate of the laminate set of adhesive coated sheet is capable of stretching the diameter of the belt so that the belt can be fitted over the transportable carrier. It may comprise an elastic material.

When a laminate set of adhesive coated sheets is used in a dispenser that includes a transfer channel that allows each laminate to be transferred to a dispensing window, a dummy pad is attached to the substrate after the final laminate of the laminate set. Is generally preferred. The provision of such a mock pad substantially improves dispensing of the adhesive coated sheet from the last stack of the laminate set of adhesive coated sheets, because if there is no mock pad, the final laminate is undesirably up and down in the dispenser. Because it happens to move. As an alternative to the use of the mock pad, means are provided in the dispenser to temporarily block the substrate of the laminate set of adhesive coated sheets. Such means include, for example, a lever or plunger. It is preferable that the laminated body set of the adhesive coating sheet provided with a flexible base material is provided in the form of a roll, or as a belt.

Each stack in the stack set is a stack of pre-cut sheets, one on top of the other, each sheet comprising a backing, the first and second opposing major sides and a sheet of each sheet. First and second opposing ends, the first ends of which are aligned with the second ends of adjacent sheets in the stack, and an adhesive layer permanently attached to the first major side of the sheet, the adhesive of each sheet The layers are releasably attached along the second side side of the adjacent sheet (lower sheet) in the stack. Each sheet is provided to provide a first adhesive plane along a first end portion of each sheet adjacent to the first end of the backing between the adhesive layer and the second major side of the adjacent sheet (lower sheet) in the stack. 1 means of leaving. The first adhesive plane is sufficiently low between the adhesive coating and the adjacent sheet (lower sheet) to allow separation (including "slide movement") between the sides of the adjacent sheet along the first end portion. Provide a force of release (eg, less than 1.97 g / mm (50 g / inch) is preferred). The adhesion plane can be conveniently understood by the method described in US Pat. No. 5,401,547, column 21, lines 31 to 47 ("leaving force").

The second release means is a second end portion of each sheet adjacent to the second end of the sheet between the adhesive layer and the second major side of the adjacent sheet (lower sheet) in the laminate to which the adhesive layer is detachably attached. Thus providing a second adhesive plane. The second adhesive plane is higher than the low release force along the first end portion and firmly attaches the sheet to adjacent sheets (lower sheets) in the stack while the sheet is separated for adjacent sheets along the first end portion. While providing a release force (preferably in the range of 5 g / mm to 17 g / mm (4 ounces / inch to 15 ounces / inch)) that causes the sheet to peel off (eg by hand) along the second end portion. .

The first release means providing the first adhesion plane and the second release means providing the second adhesion plane comprise (1) a low adhesion backsize on the upper surface portion of each sheet along only the first end portion; Provide a uniform coating of the same pressure-sensitive adhesive of each sheet with a coating of or otherwise provide a low sticking backside on the top surface of each sheet along the first end portion and the second end portion, the first end portion The low-adhesive backside of S is a structure that has the largest release factor, i.e., the lowest release value, and (2) the coating of the pressure-sensitive adhesive along each sheet, discontinuously along the first end portion. Continuously formed along the second end portion, or discontinuously formed along both end portions, and formed along the first end portion, along the second end portion; A plurality of structures including, but not limited to, a structure that forms more discontinuously than is formed, and / or (3) a structure using other pressure-sensitive adhesives along two end portions thereof, including but not limited to It includes a branch structure. In one example, the stack of sheets may comprise an adhesive layer covering over the entire first major side of the backing of each sheet, the second release means covering over at least a portion of the second major side adjacent to the second end of the sheet. And a layer of medium release low adhesion backsize (LAB), wherein the first release means includes an excess release coated over a portion of the second major side adjacent the first end of the sheet. premium release (LAB) layer of low adhesion backsize (LAB). In this embodiment, the sheets in the stack have a length along the longitudinal axis and a width along a direction perpendicular to the longitudinal axis of the stack. The layer of excess release low-adhesive back pool (LAB) is continuous and extends from the first end of the backing along the length of the sheet and comprises an area in the range of 10-80% of the area of the backing side of each sheet in the stack. do. Preferably, the excess release low tack back pool (LAB) layer preferably comprises approximately 37.5% of the area of the backing side of each sheet in the stack.

Preferably, each laminate of the laminate set of adhesive coated sheets has a tab detachably attached to the first sheet of the laminate. The tab has opposing first and second ends and includes a backing. An adhesive layer is provided on the major side of the backing portion along the first end, and at least a portion of the major side of the backing portion along the second end of the tab is free of adhesive. Preferably, the tab has a length less than the length of the adhesive coating sheet in the laminate. Preferably, the tab has a length that is about one half of the length of the adhesive coating sheet. The tab is preferably attached to the stack such that the first end of the tab containing the adhesive layer can be aligned with one end of the stack. Tabs detachably attached to each laminate are provided to facilitate slicing the first adhesive coated sheet of the laminate.

In general, the term "sheet material" as used herein generally means a flat flexible structure, preferably an acetate glossy film, matte acetate film, thermosetting film, thermoplastic film, polyester, polypropylene, Polyethylene, vinyl, paper, metal foil, non-woven or a combination of the above materials. The sheet material is preferably transparent in order to allow the user to see the underlying substrate, which may be opaque.

Low-adhesive backside pools represent materials that are easily released from the layer of pressure-sensitive adhesive, including, but not limited to, silicon, fluorocarbon, acrylate, urethane, chromium composites, grafted or block siloxane hydrocarbons, these A mixture of materials. Examples of various low tack backing pools can be found in US Pat. Nos. 4,421,904, 4,313,988 and 4,279,717, all of which are expressly incorporated herein by reference. Still other low-adhesive backside pools used in accordance with the present invention are described in US Pat. Nos. 2,607,711, 2,876,894 and 2,532,011, the entirety of which is also incorporated herein by reference.

In general, the term "premium release low adhesion backsize" as used herein refers to the interaction of adhesive / back pools with a maximum release force of less than or equal to 100 g / inch (39.4 g / cm). By “medium release low adhesion backsize” is meant the interaction of adhesive / back paste with a release force of at least 59.1 g / cm (150 g / inch). The pressure sensitive adhesive consists of acrylic, silicone, rubber-resin, or any other suitable composition. In one example, the adhesive comprises acrylic adhesive IOA (95%) / AA (4.5%) iso-octyl acrylate / acrylic acid. Adhesives used in the present invention are described in US Pat. Nos. 4,699,842, 3,578,622, 3,331,729, 2,926,105 and 4,835,217, the entire disclosures of which are expressly incorporated herein by reference. Acrylic microspheres (IOA-ammonium acrylate) are also contemplated as adhesives used according to the present invention. In one example, the readhesive adhesive may be prepared according to US Pat. No. 3,691,140, which is incorporated by reference herein in its entirety.

The present invention also provides various embodiments of dispensers for use in the laminate set of the adhesive coated sheet of the present invention. The dispenser of the present invention may generally receive a set of laminates of adhesive coated sheets containing at least four laminates, preferably at least eight laminates, more preferably at least 16 laminates. The dispenser of the present invention should include a dispensing window that penetrates as each sheet is dispensed from the stack. In addition, the stack set of dispensing window and adhesive coated sheet must be movable relative to each other so that each of the individual stacks can be below the dispensing window once one stack of the stack set is exhausted. Preferably, such movement is incremental, and means are provided to allow individual stacks in a temporarily fixed position to be held relative to the dispensing window.

According to one embodiment, the dispenser comprises one or more walls defining the shape of the dispenser and dispensing means comprising an opening in one of the walls. The opening of the dispensing means, hereinafter also referred to as dispensing window, generally has a width slightly larger than the width of the stack of adhesive coated sheets and a length slightly smaller than the length of the stack of adhesive coated sheets. In one example, the width of the distribution window can range from 100 to 120% of the width of the laminate, and the length of the distribution window can range from 20 to 90% of the length of the laminate. While it is generally important that the length of the dispensing window is smaller than the length of the stack of adhesive coated sheets, the width of the dispensing window is less important, while the width of the dispensing window allows the dispensing in multiple laminates to occur simultaneously. It may be made large enough to accommodate two or more laminates in the window.

According to an embodiment of the present invention, the openings in the wall that allow each sheet to penetrate therethrough have a substantially larger width and length than is required for dispensing the adhesive coated sheet. In this embodiment, the size of the opening in the wall can be adjusted by superimposing a second opening having a smaller dimension on the opening. Thus, in this embodiment, the dispensing means comprises an opening in one of the walls and an opening overlying this opening and having a smaller dimension than the opening in the wall of the dispenser. Dispensing windows superimposed over larger openings in the wall can be used in particular to enable different sets of adhesive coated sheet laminates having laminates of different widths and / or lengths. In yet another alternative embodiment, a shuttling dispensing window is provided at the top of the opening in the wall of the dispenser. The reciprocating dispensing window generally includes a small slot (slightly larger than the thickness of the sheet) that allows the sheet to extend through during dispensing operation, the reciprocating dispensing window from one edge over the opening along the length of the opening to the other. Reciprocate to the edge. This optional embodiment has the advantage that the sheet is always positioned upwards and therefore easy to hold. Although the distribution window is preferably rectangular, other shapes may be used, such as circular openings, elliptical openings, or openings with one or more straight edges or one or more rounded edges. The dispensing window in these embodiments is fixed, i.e., does not move relative to the set of stacks of adhesive coated sheets, so that the stack of stacks of adhesive coated sheets with respect to the dispensing window in order for the stack to reach the dispense window. You must move. Thus, the dispenser comprises conveying means for transferring the individual stacks of the stack set to the dispensing window. The conveying means may comprise a conveying channel capable of selectively connecting to a cavity in which the stack of adhesive coated sheets is stored therein, or may comprise a conveying carrier such as a rotating wheel, a rotating core or a belt. . The conveying direction of the laminate set of the adhesive coated sheet is preferably parallel to the longitudinal direction of the laminate set of the adhesive coated sheet.

In a dispenser having a conveying channel, it is preferred that the laminate set of adhesive coated sheets is a flexible substrate. By moving the leading edge of the laminate set of adhesive coated sheets, for example by hand, the other laminate after one laminate is transferred to the dispense window of the dispenser. In a dispenser with a transfer carrier, a stack of stacks of adhesive coated sheets is firmly attached to the carrier, by pulling the stack of sets each of the individual stacks of the stack set to a dispensing window whereby From the laminate.

As an alternative to moving the stack of adhesive coated sheets to the dispensing window, the dispenser may receive the stack of stacks of adhesive coated sheet in a cavity in a fixed position, and then the movable dispensing window is provided.

This stack 51A comprises only a single layer 1A of low-adhesive back pool along the second major surface 5A of the backing portion 10A of the sheet 11A. Optionally, the first release means 8A for providing the first adhesion plane and the second release means 9A for providing the second adhesion plane are provided on the backing portion 10A of each sheet 11A. A discontinuity (not shown) that forms the covering of 2A) is included in both portions, wherein the discontinuity of the first end portion 15A is larger than the discontinuity of the second end portion 17A.

Referring to FIG. 4C, there is shown a third optional embodiment of another sheet stack in the present invention, which is generally represented by reference numeral 51 and is substantially the same as the members of the stack 51 of sheet 11. Members, which are labeled with the suffix "B". In FIG. 4C, the first release means 8B for providing the first adhesion plane and the second release means 9B for providing the second adhesion plane are used to define the first end portion 15B and the second end portion 17B. Therefore, the structure which changes the composition of the coating | coated part of pressure-sensitive adhesive 2B is included. Like the stack 51A, the stack 51B includes only a single layer 1B of low sticky backside pool along the second major surface 5B of the backing portion 10B of the sheet 11B. The adhesive 13 used along the first end portion 15B as an example of the laminate 51B may be a relatively weak or low aggressive adhesive as described in US Pat. No. 3,691,140. Adhesives particularly suitable for use along the first end portion 15B include acrylic adhesives or acrylic microspheres. The adhesive 13B used for the second end portion 17B may be a relatively active or strong adhesive such as acrylic adhesive, rubber resin, or the trade name KRATON. Adhesives for use in the present invention are prepared according to US Pat. Nos. 4,699,842 and 4,835,217.

The pre-cut sheet of the present invention is generally used for tasks other than dispensing tape, such as for gift wrapping, packaging, wrapping books, sealing boxes, winding medical tape, marking and highlighting wires, and the like. This is especially useful for doing things that require using both hands. In addition, in dispensing the adhesive coating tape separately, no cutting operation is required, thereby facilitating and dispensing the adhesive coating tape easily. Further, according to the laminate set and dispenser of the adhesive coated sheet of the present invention, the user can secure a large number of pre-cut sheets.

The substrate 50 to which the laminates 51, 51A, 51B are attached may be a flexible substrate as well as a rigid substrate. The flexible substrate is preferably used with the dispenser of the present invention having a dispenser or transfer channel of the present invention comprising a transferable carrier which brings a new stack under the dispense window of the dispenser. When the dispenser comprises a transportable carrier to which a stack of laminates of adhesive coated sheets is attached, the substrate 50 is repositionable adhesive on a side opposite to the side receiving the stack of adhesive coated sheets. " The term " repositionable adhesive " in connection with the present invention allows the substrate 50 to be firmly attached to the transferable carrier during dispensing operations, but the stack of laminates of adhesive coating sheets is exhausted. Once it has been done, it means that the substrate can be removed from the transportable carrier without leaving a substantial residual amount of adhesive .. Examples of suitable adhesives include pressure-sensitive adhesives used in post-it notes. Optionally, the substrate 50 has a leading edge and / or on a substrate 50 free of the stack 51 of adhesive coating sheet. It is firmly attached by providing a distal edge .. A stack set of adhesive coating sheets comprising a distal edge 53 is shown in Fig. 5. Such distal edge and / or distal edge may then be distal or distal. It is inserted into one or more slots configured in the transportable carrier to receive the edges, and also for use with a dispenser of the invention using a repositionable adhesive or having a dispenser window that has a distal and / or distal edge. The laminate set of adhesive coated sheets can then be preferably held in a fixed position.

In the case where the substrate 50 is a flexible substrate, it is generally desirable to provide a laminate set of an adhesive coating sheet in roll form or belt form as shown in FIG. Also shown in FIG. 5 is a dummy pad provided attached to the substrate 50 behind the last laminate of the laminate set of adhesive coated sheets. In general, the dummy pad 52 is a pad having substantially the same dimensions as each laminate of the laminate set but not including the adhesive coating sheet. Examples of mock pads 52 include hollow plastic rods. The use of imitation pads works advantageously in distributors employing transfer channels. In such a dispenser, the dummy pads can substantially avoid movement of the stack set when the sheet is dispensed from the last stack of the stack set of adhesive coated sheets.

Examples of flexible substrates to which the laminate is attached include polyethylene films, cellulose acetates, polypropylene films, polyester films, nonwovens, woven fabrics, polyethylene or polypropylene coated papers, plain papers, and light cardboards. do. The thickness of the flexible substrate is usually 0.05 mm to 1 mm, preferably 0.15 mm to 0.5 mm. Each of the laminates 51, 51A, 51B is preferably attached to the flexible substrate with the length of these laminates aligned with the width of the flexible substrate. The stacks 51, 51A, 51B are preferably attached to the flexible substrate by the adhesive layer of the last sheet in the stack. However, it is also possible to attach the last sheet in the laminate to the backing, which is then attached to the flexible substrate with an adhesive such as a pressure sensitive adhesive, for example.

When the substrate 50 is provided with a rigid substrate, it is preferred that the set of adhesive coating sheets is not substantially planar. If the rigid substrate is substantially planar, neighboring stacks in the stack set will adhere to each other, causing difficulties in dispensing each sheet from the stack. The rigid substrate is preferably arcuate or a core, for example a cylindrical shim, with each laminate attached to the outer peripheral surface of these arched substrates or shims.

The laminate set of adhesive coated sheets according to the present invention is made by forming each adhesive coated sheet laminate as illustrated in the examples of US Pat. No. 5,401,547. In this case, each adhesive coating sheet is laminated in a Z shape on the back sheet having the same dimension as each adhesive coating sheet. Therefore, such a laminate includes a back sheet as a bottom sheet. In order to obtain a laminate set of the adhesive coated sheet of the present invention, each such laminate is attached to the substrate with an adhesive such as a pressure sensitive adhesive or a hot melt adhesive. Optionally, another second release means is employed to attach each stack to the substrate 50. This second release means includes hook or loop attachments under the trade name SCOTCH, commercially available from 3M, or connecting fasteners, also available from 3M. According to a particular embodiment of the invention, each laminate is attached to the adhesive tape by placing them in successive rows next to each other on the adhesive coated side of the adhesive tape.

According to an alternative embodiment for making a laminate set of adhesive coated sheets of the present invention, a single pad of adhesive coated sheet of length L and width W is generally subjected to the procedure illustrated in the examples of US Pat. No. 5,401,547. Are manufactured accordingly. As mentioned above, the lowest sheet in this pad of adhesive coated sheet will be the back sheet and each adhesive coated sheet is stacked in a Z-shape so that the first release means 8 and the second release means 9 are pads. It will be filtered one by one between the edges defining the width of. In order to obtain a laminate set of the adhesive coated sheet of the present invention, the pad of the adhesive coated sheet is cut at a regular distance R along the length L. However, the cutting of the pad is carried out in a manner called so-called kiss-cutting in which each of the adhesive coated sheets is cut in its entirety but the back sheet does not cut completely through. The term "not completely cut through" means that at least 10%, preferably at least 20%, of the back sheet is not cut. Thus, n stacks of width R (the product of R and n correspond to the length L of a single pad excluding potential residues) and width W (corresponding to the width of a single pad) are obtained. The back sheets serving as the substrate 50 remain attached to each other. Kiss-cutting of the pad is performed in several ways. In one example, the contact cutting is performed with a knife that cuts completely through a portion of the back sheet along the width W while leaving other portions along the width W partially uncut. For example, cut through the back sheet completely at both edges of the pad, leaving the back sheet uncut at the center along the width W of the pad, or vice versa with the back sheet partially cut at the edges. A knife can be used which cuts completely through the back sheet in the center along the width W, leaving behind. An advantage of partially cutting through and partially not cutting through the back sheet is that the flexibility of the substrate 50 is further increased.

As an alternative to the embodiment described in the previous paragraph, to provide a set of laminates of adhesive coated sheets having a rigid shim as a substrate, a single pad of Z-shaped laminated adhesive coated sheets is wound around the shim and then the single The pads are kiss-cut at regular intervals around the seam.

The conveying channel 49 holds a stack set 70 of adhesive coated sheets. The laminate set 70 of the adhesive coating sheet preferably includes a tip portion in which the substrate 50 does not receive the laminate 51. The length of this tip should be at least equal to the length of the conveying channel between the opening 42 and the discharge opening 43. Although a stack set 70 of adhesive coated sheets can be fed into the transfer channel 49 via an inlet opening 44, at least one sidewall of the two side walls 48 is movable so that the stack of adhesive coated sheets is movable. It is desirable for the conveying channel 49 to be accessible from one of the sides of the dispenser so that the set 70 can be easily mounted in the dispenser. The transfer channel 49 should have at least a width and a height so that the stack of sets 70 of adhesive coated sheet can be easily fastened into the transfer channel. Typically, the conveying channel 49 has a slightly larger width and height than the width and thickness of each of the stack set 70 of adhesive coated sheets. However, as shown in FIG. 7B, the height of the portion of the conveying channel 49 between the opening 42 and the discharge opening 43 is only slightly larger than the thickness of the substrate 50 of the laminate set 70 of the adhesive coating sheet.

The operation of dispensing the adhesive coating sheet from the laminate set of adhesive coating sheets in the dispenser 90 is shown in FIGS. 6A-6D. 6A and 6B are partial cross sectional views through the distribution window of the dispenser 90. As can be seen from these figures, when the sheet 12 is pulled from the stack, the sheet 14 below it is released from the sheet 16 under the sheet 14, and the sheet 12 is subsequently removed. When pulled out, the edge 20 of the sheet 14 eventually emerges through the opening 92. Subsequently pulling the sheet 12 causes the sheet 12 to be detached from the sheet 14 while leaving the sheet 14 detachably attached to the sheet 16, which separation operation may be repeated. Once one stack of the stack set is exhausted, the next stack of stack set is below the opening 92 once the substrate is pulled. This operation is convenient, quick and easy. Thus, a heavy duty user can obtain a large number of adhesive coated sheets without frequent filling the dispenser as in the case of the dispensing system described in US Pat. No. 5,401,547, for example.
