上），徑向部件112a、112b之傾斜邊緣用以將卷丨5^導引至 一大約居中位置。然後，徑向部件112b(其位置係可調節 的）可以一合作方式向外移動以便接觸卷15〇之内表面156 以將卷150推動至一居中位置中以使該卷之圓柱體軸線與 可旋轉心軸109之旋轉軸線B吻合。當已用光一捲之片材 1 50時’徑向部件1丨2b可向内徑向伸縮。 圖3圖解說明一支撐輥軸總成1〇4之一側剖視圖，該支撐 輥軸總成包含經由適合的軸承支撐支撐輥軸1〇6之一内部 支#部件110及一外部支樓部件108。如圖3中所圖解說 明’圓錐形支撐輥轴106各自具有帶有一寬端及一窄端之 一圓錐形形狀’其中圓錐形支撐輥軸106中之每一者具有 154829.doc 201200449 各自旋轉轴Ce圓錐形支撑親抽i〇6經定向以使其各自旋 轉軸線C徑向指向可旋轉心軸之旋轉軸線B(亦即，指向卷 150之一中心）且相對於垂直於可旋轉心軸之旋轉軸線b之 一水平方向上以一角Θ定向，以使接觸卷15〇之底部之圓錐 形支撐輥軸106之部分大致水平配置。圓錐形支撐輥軸1 % 之此定向準許沿每一支撐輥轴1〇6之長度支撐卷15〇之平坦 底部。每一支撐輥軸總成1〇4亦可包括其旋轉軸線平行於 外部支撐部件108所支撐之旋轉軸線B而定向之一側輥軸 111，其中側輥轴111可提供橫向支撐以防止捲之片材i 5〇 徑向向外移位經過支撐輥軸1 〇6之一外部邊緣。 可基於預期捲之片材之預料大小來選擇圓錐形支撐部件 106之尺寸。一典型卷15〇可具有（例如）約24吋之一内直 徑、約40吋之一外直徑及約36吋之一高度。一般而言每 一圓錐形支撐輥軸106之長度應至少與卷15〇之内半徑與外 半徑之間的差一樣大，亦即，每一圓錐形支撐輥軸1〇6之 長度應至少與卷150上所捲繞之片材之半徑寬度一樣大。 為容納典型大小之捲之片材，圓錐形支撐輥轴106可係約 12.3吋長，其中一窄端直徑係約2 25吋且一寬端直徑係約 5-3吋。支撐輥軸1〇6之窄端可定位於離可旋轉心軸1〇9之 旋轉軸線B(亦即，離卷15〇之圓柱體軸線）約9吋之一距離 處，且支撐輥軸106之寬端可定位於離旋轉轴線B約123吋 之距離處。應根據關係式R1/R2=A1/A2來選擇圓錐形支 撐輥軸106之寬端及窄端直徑，其中A1係輥軸1〇6之窄端處 的一直徑，A2係輥軸106之寬端處的一直徑，R1係旋轉 154829.doc 201200449 轴線B離直徑A1處輥轴106上之一接觸點的一距離，且R2 係旋轉軸線B離直徑A2處輥軸106上之一接觸點的—距 離，諸如圖3中所顯示。根據滿足此關係式來選擇該等支 撐輥軸尺寸確保在離旋轉軸線B之任一給定距離處，片材 在支撐輥軸106上之運載線速度匹配彼點處支撐輥軸1 〇6之 表面之線速度。因此，R1及R2可經選擇以適應卷之預料 大小，A1可經選擇至一期望值（例如，足夠大以達成期望 的結構強度，諸如例如，2.2 5叫*、2.5 σ寸、3 11寸等），且然後 可基於Rl、R2及Α1來計算Α2。如自圖3可見，可藉由 sine=Al/(2.Rl)=A2/(2.R2)給出角Θ。熟習此項技術者可馨

捲開器不具備一夾持機構，則一大的c形夾具可適當定位 並夾緊至卷150之内表面及外表面以便鬆開某一長度之片 材以使得其可饋送至一毗鄰機器中並有效地固持以防止解 開。若捲開器包括用於驅動支撐輥軸1〇6中之一者或多者 之一驅動機構，則彼驅動機構可經操作以促進最初將來自 154829.doc 201200449 卷之片材饋送至一眺鄰機器中。 與習用捲開系統相比，根據本發明之捲開器可具有各種 優點’該等捲開器經建構以使得卷之圓柱形軸線在使用期 間定向於一水平方向上。舉例而言，藉由如本文所繪示垂 直疋向捲開器’可在考量到用於金屬形成之其他器材將靠 近捲開器100、200而定位時提供相當程度的總密實度。藉 由提供一垂直定向之捲開器，其他金屬形成設備亦可與傳 統水平定向相反地垂直定向，以使得可在一裝輪拖車之平 臺上有效放置更多ϋ材。對於其中建築構造器材須運輸至

OBJECTS OF THE INVENTION: FIELD OF THE INVENTION The present invention relates to apparatus for constructing metal construction at a work site, and more particularly to feeding metal sheets for use in the manufacture of metal construction panels. The roll-off system of the device. The present application claims priority to U.S. Patent Application Ser. [Prior Art] In the construction process of a metal building, the metal sheets can be rolled and bent into a metal building board, and then the building boards can be fastened together to form a metal building. Metal sheets of various sizes (thicknesses) are usually manufactured, shipped and stored in the form of large diameter rolls. The rolled metal sheets are unrolled so that they can be fed into equipment that performs various roll forming operations. Various devices for unwinding sheets are known in the related art, such as U.S. Patent Nos. 4,160,531, 2,020,889, 2,762,418, 6,691,544, RE 20,000, 2,757, 880, 2, 899, 145, 2, 653, 643 and 4, 094, 473 The application is disclosed in 2〇〇7〇17〇3〇1. One of the conventional devices is typically characterized in that it is constructed to horizontally support a roll of sheet material (i.e., such that the axis of rotation of the sheet of the roll (i.e., the cylinder axis of the roll) is oriented relative to a vertical direction ( The vertical direction is oriented horizontally along one of the directions of gravity. Conventional devices may include a horizontal mandrel or shaft to support the roll from inside a cylindrical hollow core of the roll. Conventional devices may also include horizontally supported roller shafts. The length of the horizontal support roller shafts spans the width of the roll I54829.doc 201200449 and its axis of rotation is oriented horizontally to support the roll from the outermost surface of the roll. The inventors have observed a need for a roll-off device that can support and unwind a roll, wherein the roll's axis of rotation (cylinder axis) is oriented generally vertically. SUMMARY OF THE INVENTION According to an exemplary embodiment, a device for unrolling a roll of paper includes a support frame supported by a supportable rotatable mandrel that is configured to be positioned In a hollow core of a roll of sheet material, the rotatable mandrel has an axis of rotation that is oriented in a generally vertical direction; and a plurality of conical support roll shafts supported by the support frame. The plurality of conical support reels are constructed as one of the bases of the sheet of the roll, each conical support has a conical shape with a wide end and a narrow end, and each conical support roll has a The axis of rotation, each conical support roll axis is configured such that its respective axis of rotation is directed toward the axis of rotation of the rotatable mandrel, each cone-shaped support roll axis being configured to position its narrow end toward the rotatable mandrel. According to another exemplary embodiment, the apparatus can include an adjustable frame assembly that supports the support frame, wherein the adjustable frame assembly is configured to controllably change one of the orientations of the support frame. [Embodiment] FIG. 1 illustrates an exemplary unwinding device 1 (also referred to herein as a reel) in accordance with an exemplary embodiment. As shown in FIG. 1, the unwinder 1A includes a frame 102 (eg, a horizontal metal platform) and a plurality of support roller axle assemblies 104 supported by the frame 1〇2, each supporting roller axle assembly 1 The crucible 4 includes a conical support roller shaft 106, an outer support member ι 8 and an inner support member 154829.doc 201200449 110. The inner and outer support members 11() and 108 support each of the stick shafts 106 via suitable bearings. In the example of Figure 1, there is one of four support roller axle assemblies 104' that are blocked. The reel 100 also includes a central rotatable mandrel 109 for centering a roll of sheet material on the unwinder 1 . 2 illustrates a reel 100 with a roll of sheet 15 positioned thereon, wherein the roll of sheet 15 has an outer surface 152, a hollow core 154, and an inner surface 156 of the hollow core 154. . By comparing Figures 1 and 2, the rotatable mandrel 109 is positioned to mate with the bottom opening of the hollow core 154 of one of the rolled sheets 150. Also shown in Figures 1 and 2, the dashed line "B" indicates the axis of rotation of the rotatable mandrel 1 〇 9 which coincides with the cylinder axis of the roll 150. The axis of rotation "b" of the mandrel 〇 9 is oriented perpendicular to one of the horizontal planes associated with the frame 102 (e.g., 'one of the platforms', as shown in the examples of Figures 1 and 2). The axis of rotation b is oriented substantially perpendicularly in the Z direction when the reel is in use. As used herein, "substantially perpendicular" means that the axis of rotation B of the winder is within a few degrees of gravity (e.g., < 1 to 2 degrees or less). In other words, when the support frame 102 is oriented horizontally within a few degrees (e.g., 1 to 2 degrees or less) of the "horizontal plane", the axis of rotation B will be oriented substantially vertically. Referring again to the example of FIG. 1, the rotatable mandrel i 〇 9 can include a rotating platform 114 (eg, a "metal disc"), a set of radial members 112a and 112b supported by the rotating platform 114, and a vertical shaft 116 ( And associated housing and bearing) and a cap 118 that secures and/or guides one of the radial members 112a, 112b. The rotatable mandrel 109 can include an adjustable mechanism in which some of the radial members 112b are movable inwardly and inwardly of the 154829.doc 201200449 via a scissor mechanism in a radial direction perpendicular to the axis of rotation B, while other radial directions The part U2a has a fixed position. A suitable scissor mechanism can be provided, for example, by attaching a lower linkage of the scissor mechanism to a vertical sleeve at the center of the mandrel 1G9 and on the outer surface of the rotating shaft. When the sleeve is pushed up (eg, via hydraulic pressure), the upper and lower scissor linkages are brought closer together to radially move the radial member 112b outwardly, and vice versa... the control switch 170 can control the hydraulic pressure ( It is further explained below to expand or expand the radial component 11. Of course, the position of the control radial member 丨i 21? can also be controlled via a wedge mechanism rather than a scissor mechanism and will be driven by one skilled in the art to understand one hand crank instead of liquid waste. The radial members 112&, U2b are preferably shaped to have a sloping upper edge as shown in the figures for when a roll of sheet 15 is positioned to the reel (eg, 'hanged from a crane or forklift) The cable descends to the unwinder J )) and the slanted edges of the radial members 112a, 112b are used to guide the rim 5 to an approximately centered position. The radial member 112b (which is positionally adjustable) can then be moved outwardly in a cooperative manner to contact the inner surface 156 of the roll 15 to urge the roll 150 into a centered position to bring the cylinder axis of the roll The axis of rotation B of the rotating mandrel 109 coincides. When a roll of sheet 1 50 has been used, the radial members 1 2b can be radially expanded and contracted inward. 3 illustrates a side cross-sectional view of a support roller axle assembly 1B including an inner support member 110 and an outer branch member 108 supported by a suitable bearing support roller shaft 1〇6. . As illustrated in Figure 3, the conical support roll shafts 106 each have a conical shape with a wide end and a narrow end, wherein each of the conical support roll shafts 106 has 154829.doc 201200449 respective rotational axes The Ce conical support protons 6 are oriented such that their respective axes of rotation C are directed radially to the axis of rotation B of the rotatable mandrel (ie, to the center of one of the rolls 150) and to the axis perpendicular to the rotatable mandrel One of the axes of rotation b is oriented at an angle 水平 in the horizontal direction such that a portion of the conical support roller shaft 106 at the bottom of the contact roll 15 is substantially horizontally disposed. This orientation of the conical support roller shaft 1% permits the flat bottom of the roll 15〇 to be supported along the length of each support roller axis 1〇6. Each of the support roller shaft assemblies 1〇4 may also include a one-side roller shaft 111 whose rotation axis is parallel to the rotation axis B supported by the outer support member 108, wherein the side roller shaft 111 may provide lateral support to prevent the roll The sheet i 5 移位 is displaced radially outward through one of the outer edges of the support roller shaft 1 〇6. The size of the conical support member 106 can be selected based on the expected size of the sheet of the desired roll. A typical roll 15 can have, for example, a diameter within one of about 24 inches, an outer diameter of about 40 inches, and a height of about 36 inches. Generally, the length of each conical support roller shaft 106 should be at least as large as the difference between the inner radius and the outer radius of the coil 15〇, that is, the length of each conical support roller shaft 1〇6 should be at least The sheet wound on the roll 150 has the same width as the radius. To accommodate a sheet of typical size, the conical support roll 106 can be about 12.3 inches long, with a narrow end diameter of about 2 25 inches and a wide end diameter of about 5-3 inches. The narrow end of the support roller shaft 1〇6 can be positioned at a distance of about 9吋 from the rotation axis B of the rotatable spindle 1〇9 (ie, the cylinder axis from the roll 15〇), and the support roller shaft 106 The wide end can be positioned at a distance of about 123 离 from the axis of rotation B. The wide end and the narrow end diameter of the conical support roll shaft 106 should be selected according to the relationship R1/R2=A1/A2, wherein a diameter at the narrow end of the A1 type roll shaft 1〇6, and the width of the A2 type roll shaft 106 A diameter at the end, R1 is rotated 154829.doc 201200449 A distance of the axis B from a contact point on the roller shaft 106 at the diameter A1, and R2 is a point of contact of the axis of rotation B from the roller shaft 106 at the diameter A2 - distance, such as shown in Figure 3. The support roller shaft dimensions are selected according to the satisfaction of this relationship to ensure that at any given distance from the axis of rotation B, the carrier linear velocity of the sheet on the support roller shaft 106 matches the support roller axis 1 〇 6 at the point. The line speed of the surface. Thus, R1 and R2 can be selected to accommodate the expected size of the roll, and A1 can be selected to a desired value (eg, large enough to achieve the desired structural strength, such as, for example, 2.2 5 *, 2.5 σ, 3 11 inch, etc. ), and then Α2 can be calculated based on R1, R2, and Α1. As can be seen from Fig. 3, the angle Θ can be given by sine=Al/(2.Rl)=A2/(2.R2). Those skilled in the art will be able to select a suitable size for supporting the roller shaft to accommodate other roll sizes, as explained above. The materials used to make the various components of the reel 100 and other unwinding devices described herein can be selected based on the anticipated size and weight of the roll to be adapted. The sheet of sheet 1 50 may be, for example, a galvanized steel sheet metal, other types of steel, hot keys (four), (d), words, or other sheets. The thickness of the sheet may be between about 0.035 leaves and about 〇. Between the breaks. As noted above, a typical roll for metal construction can have, for example, an internal material (i.e., the diameter of the center 124 is about (4)), about (4) - the outer diameter, and the force. 36 degrees of π degrees. The weight of such rolls can generally be, for example, between about 〇 〇 and 9 _ 碎. The materials used in the manufacture of the various components of the reel according to the present invention should be selected to accommodate the weight of the roll being used. For example, the frame piece can be made of, for example, a thickness of 5 New Zealand (4), a non-recorded steel or a thin alloy sheet, and a 'building roller shaft can be made of non-recorded steel, and the connecting rod and the coupling can be tied. Made of stainless steel or hardened steel, the bearings and gears can be made of hardened steel. Figure 4 shows additional details regarding the rotatable mandrel 1〇9 and associated components. As shown in Figure 4, the radial position of the adjustable radial member ii2b can be controlled via a scissors mechanism. In the example of FIG. 4, a first scissor arm i26=- is rotatably mounted to an inner support member 丨2 2 via a fastener 130 (eg, a bolt, bolt, etc.) at the upper end, wherein the inner support member i 2 2 has a vertical slot in its ^. One of the opposite ends of the first scissor arm 126 is freely seated in the vertical slot of the radial member 112b as it is guided by a fastener 130 through a scissor arm seated in one of the vertical slots of the support member 12. Move down. A second scissor arm 128 is rotatably mounted to an upper portion of the radial member 112b via a fastener 13 其 at an upper end thereof, and a lower end of the second scissor arm 12\ is rotatably Mounted to a sleeve 124 that can be moved up and down, for example, under the control of a hydraulic mechanism. As further shown in Fig. 4, the rotatable mandrel 1 〇 9 is supported by a bearing housing 138 including a bearing housing and associated bearings and a shaft 14 ,, wherein the bottom flange 139 of the bearing housing 138 can be assembled! One of the frames 1〇2 shown in the horizontal sheet component. The bearing housing 138 has a hydraulic cylinder 136 associated with a vertical hydraulic shaft that can move up and down the upper and lower drive shafts 116 under the control of a hydraulic control mechanism. The upper end of the shaft jig driven by the hydraulic cylinder 136 is via A bearing drives the bottom portion of the sleeve 124 upwardly such that the entire rotatable mandrel 109 is rotatable about the shaft 116 such that the shaft 116 itself does not need to be rotated. By moving the shaft 116 upward using the liquid red 136, the radial member 112b can be moved outwardly in a radial direction to center and hold the roll 15 in place. By reversing the pressure in the hydraulic cylinder or by lowering the shaft 116, the radial member 112b can be moved inward in the radial direction to release the radial member 112b and/or change its position. To accept a new volume bo. The reel 100 can also include a tensioning mechanism for resisting rotation of one of the rotatable mandrels 1〇9 to permit tensioning of the sheet as it is fed from the roll 150. As shown in FIG. 4, for example, the tensioning mechanism can be provided by mounting to one of the disk members 144 of the rotating disk 114 that rotates with the rotatable spindle, and a brake can be applied via a hydraulic cylinder 142. The shoe 144 or other device is pressed against the disk member to provide a controllable friction against the disk 144 against rotation of one of the rotatable spindles 109. Each of the hydraulic cylinders 136 and 142 can be actuated by a control panel (not shown) having a plurality of valves for controlling the pumping of hydraulic fluid from a hydraulic pump to the respective hydraulic cylinders 136 and 142. The control panel and hydraulic pump can be supplied to the detachment structure of the detachment of the detachment (for example, the trailer can be towed - behind the truck - the action trailer). An exemplary roll-up FIG. 5 illustrates an outer device 200 having an adjustable frame structure that permits adjustment of one of the reelers (for example) for use in the support frame 2 of the reel 200 2 is rotated by almost 9 degrees to position the winder 200 in a non-use position for transport to or from a work location. The reel 2 is similar in many respects to the reel 100 described above and includes a rotatable member with an expandable radial member U2b. A shaft (10), a plurality of support roller shaft assemblies HM having a _-shaped field, a controllable hydraulic control for the adjustable spindle 1〇9, a control switch 17〇, etc., such as the above The device is closed. In addition, as shown by comparing Figures 5 and 6, the unwinder fan also includes 154829.doc -11 - 201200449 containing a frame assembly that permits the support frame 202 to be rotated by almost 90 degrees. This aspect will now be further elaborated. Specifically, referring to FIGS. 5 and 6, the support frame 2〇2 of the unwinder 2〇〇 further includes a first frame member 250, a first hinge frame arm 252, a second frame member 254, and a second One of the frame assembly arms of the hinged frame arm 256. The first frame member 250 and the second frame member 254 can be mounted (e.g., welded or otherwise fastened) to a support structure 290 (e.g., one of the steel frame members of a wheeled trailer). The frame assembly also includes first and second hydraulic cylinders 258 and 260' each including a vertical shaft rotatably coupled to the support frame 202 via a suitable hinge mechanism. By actuating the hydraulic cylinders 258 and 26〇 shown in Fig. 5 by means of a control switch (not shown), the associated vertical shafts of the hydraulic cylinders 258 and 26〇 can be translated upwards, and the rear side of one of the support frames 202 is also hydraulically The shafts of cylinders 258 and 260 are upwardly moved to translate upwardly to position the winder 200 in the orientation shown in FIG. As shown in Figure 5, the winder 200 can also include a set of guide rollers 272, 274, 276 supported by a frame (e.g., frame member 256 in this example) to self-wind with one of the sheets. It is guided around, wherein the guide rollers 272, 274, 276 have an axis of rotation oriented parallel to the axis of rotation B of the rotatable mandrel 1〇9. Of course, the guide rollers 272, 274, 276 can be positioned at other locations on the reel 200 and can be branched by other frame portions. Referring again to FIG. 5, the reel 200 can also include a radially adjustable clamping mechanism 280 that can include a radially inward and outward movement relative to the volume 150. The outer sheet is positioned to prevent it from unwinding one of the vertically oriented pinch rollers 282 when the retaining sling of the roll is released. In the example of FIG. 5, 154829.doc • 12·201200449, the gripping roller shaft 282 of the adjustable clamping mechanism 180 can be controlled via a one-hand crank mechanism having a socket that accepts one hand crank as shown in FIG. The position ' is such that the hand crank is rotated such that the rotation is blocked by one of the screws to translate the vertical pinch roller shaft 282 radially inwardly and outwardly in a direction that is viewed in the direction in which the hand crank is rotated. Unrolling the H2GG may also include a drive mechanism to drive at least at least of the conical pivot shaft 1G6 to rotate the roll, for example, to facilitate feeding the sheet from the roll 15 to the alt-o-metal forming apparatus. Fig. 7 shows a detailed view of the reel, and in particular shows a drive mechanism 3 for driving one of the conical support rollers 1〇6 which will be further explained with reference to Fig. 8. As shown in FIG. 8, the drive mechanism 300 includes a socket assembly 302 that can receive a hand crank, a shaft 306 that can be driven by a crank, and a variety of other sprockets, shafts that rotate a pair of conical support rollers 106. gear. In particular, the rotational motion of the shaft is transferred to a sprocket 308 that rotates one of the two sprocket wheels 3ι via a chain 312. Each sprocket 31 is coupled to and drives a shaft 314 that drives a bevel gear 310. Each of the bevel gears 316 in turn drives another bevel gear 318 that is coupled to a shaft 320 (since the left hand side supports the roller shaft ι6, the shaft 320 is blocked by the bevel gear 322 to the shaft 32 (), which then Another bevel gear 324 that is coupled to the roller shaft 106. Thus, in this example, the winder 200 includes a pair of opposed conical supports that can be rotated to assist in rotating about the axis of rotation B of the rotatable mandrel 109. One of the rolls 15 驱动 drive mechanism 300. It will be appreciated that the features of the reel 2 图 illustrated in Figures 5 and 6 can also be used in conjunction with the reel 1 图 shown in the figures. Such as a tensioning mechanism for 154829.doc -13-201200449 against rotation of the rotatable mandrel 109, a drive system for driving one or more conical support rollers 1〇6, for self-winding The sheet removes the sheet and the guide sheet guides the parent axis and a radially adjustable gripping mechanism including the vertically oriented grip roller shaft. The reel 1 can be operated in a manner that is always available. And 2〇(). First, in the case where the cylindrical axis of the coil is vertically oriented (a One end of the sling is threaded through the hollow core 56 of the roll 150 and the other end of the same sling is directed upward along the outer surface of the roll 150 by winding three or four slings on the sheet And a roll of sheet 150 is lowered to the unwinder 1 〇〇, 2 使用 using a crane or a car to lift the roll 15 自 from above via a sling, and then the roll 15 〇 is lowered to the unwinder 150 If the reel has four support rollers (10), the use of four slings can be advantageous 'this is because the slings can be positioned between the support rollers. Similarly, if the reel It is advantageous to have three support rollers 106' using a two-stay sling. This roll will still have a metal grip sling around one of them to prevent the sheet from unraveling (by means of such gripping slings) Rolling to prevent uncoupling. If the reel has a clamping mechanism (such as clamping mechanism 280), the clamping mechanism can be positioned to cause the vertical clamping roller shaft 282 to push the outer sheet of the roll (see, for example, Figure 5) ^ With the clamping roller shaft 282 properly positioned, the metal clamping slings present on the roll can be removed. With a clamping mechanism, a large c-shaped clamp can be properly positioned and clamped to the inner and outer surfaces of the roll 150 to release a length of sheet so that it can be fed into an adjacent machine and effectively Hold to prevent unraveling. If the unwinder includes a drive mechanism for driving one or more of the support roller shafts 1〇6, the drive mechanism can be operated to facilitate the initial roll from 154829.doc 201200449 The sheet is fed into a neighboring machine. The reel according to the present invention can have various advantages over conventional roll-off systems. The reels are constructed such that the cylindrical axis of the roll is oriented during use. In the horizontal direction, for example, by means of a vertical twister as illustrated herein, a substantial degree of total compactness can be provided when considering that other equipment for metal formation will be positioned close to the winders 100, 200. degree. By providing a vertically oriented unwinder, other metal forming equipment can also be oriented vertically opposite the conventional horizontal orientation so that more coffins can be effectively placed on the platform of a wheeled trailer. This is a significant advantage for mobile applications where building construction equipment must be transported to a work location. In addition, the vertical unwinder according to the present invention naturally avoids undesired displacement of one of the layers of the "stacked" axially wound material so that one end of one or several layers extends beyond the roll. One end. The retraction in the conventional reel can cause alignment problems and, in severe cases, can make a roll unusable so that the operator must manually level the S before the roll can be used. The vertical reel according to the present invention avoids collapsing, however, by gravity causing the bottom edge of all layers of the sheet of the roll to remain desirably against the support axis supporting the weight of the roll. The present invention has been particularly described and illustrated with reference to the exemplary embodiments thereof, and it will be understood by those skilled in the art that the details of the invention may be described or illustrated without departing from the spirit and scope of the invention. make change.
