[Paper binding tool 1]
First, a paper binding tool 1 according to the present invention will be described with reference to FIGS. 1 to 3.
The paper binding tool 1 is formed from a laminated paper 101 (see FIG. 5) in which two relatively thick papers (about 0.5 mm) are stacked and bonded together, and a plurality of ring portions 2, 2 and the belt-like margin part 3 which connects the one end side of this ring part 2 * 2 ....

  The laminated paper 101 is composed of an outer paper 2a that is an outer peripheral surface of the ring portion 2 and an inner paper 2b that is also an inner peripheral surface. In this embodiment, the outer paper 2a is heated on the surface facing the inner paper 2b. An adhesive made of a sealing agent is pasted, and both sheets 2a and 2b are pasted together. That is, an adhesive layer 2d (see FIG. 2) made of a heat sealing agent is provided between the outer paper 2a and the inner paper 2b, and can be easily obtained by pressing and heating the ring portion 2 of the laminated paper 101. Molding is possible.

  Here, the method of adhering the outer paper 2a and the inner paper 2b is not limited to this. For example, the heat sealing agent is applied to the opposing surfaces of the two papers 2a and 2b, respectively, so that the adhesive force is stronger. It may be a thing. Further, the adhesive is not limited to the heat seal agent, and may be other glue or glue, for example. In particular, molding can be easily performed by using a thermoplastic adhesive or an adhesive that cures by overheating. In addition to the application of the liquid heat sealant, the adhesive layer may be configured by sandwiching a sheet or tape-like heat sealant therebetween.

  As will be described later, the ring portion 2 is a portion obtained by bending a comb-tooth-like tooth portion to be formed on one end side of the laminated paper 101 into a cylindrical shape, and the tip portion thereof is formed in a semicircular shape in plan view. Further, a flat portion 2c that is bent in a direction opposite to the cylindrical curve direction is formed at the tip of the ring portion 2, and the tip of the inner paper 2b is removed from the flat portion 2c. As a result, the heat sealing agent that is the adhesive layer 2d is exposed at the tip of the ring portion 2.

  The band-shaped margin 3 is a part that supports the bases of the ring portions 2, 2... In parallel at one end of the plurality of ring portions 2, 2. Are provided opposite to the flat portions 2c, 2c. That is, the belt-like margin part 3 is also formed by being bent in a direction opposite to the cylindrical curve direction, like the flat part 2c, and its plane width is slightly larger than the length of the flat part 2c. .

  The paper binding tool 1 having such a shape is used for bundling one end of a plurality of sheets 51, 51,..., Such as a desktop calendar 50 and a notebook as shown in FIG. It is done.

  That is, the upper ends of the plurality of sheets 51, 51,... Are provided with a plurality of binding holes 51a, 51a,. The width dimension of the binding holes 51a, 51a,... Is larger than the width dimension of the ring portion 2 of the paper binding tool 1.

  That is, the flat portion 2c of the ring portion 2 inserted through the binding hole 51a of the sheet 51 faces the strip-shaped blank portion 3 with the inner surface side of the exposed outer paper 2a, that is, the surface to which the heat sealant is applied. The ring portion 2 of the paper binding tool 1 is bound by superimposing the flat portion 2c and the belt-like margin portion 3 so as to join each other and simultaneously performing heat pressing.

  As described above, the paper binding tool 1 is used for bundling a calendar or a booklet composed of a plurality of sheets 51, 51,... Having binding holes 51a, 51a,. Thus, unlike a conventional calendar using a metal or plastic binding tool, the paper product can be made 100%, and the cost at the time of disposal can be reduced, which is economical.

  Here, as will be described later, the paper binding tool 1 according to the present invention is formed to have a certain length in which a plurality of ring portions 2, 2,... Are continuously connected in a band shape. Is used by cutting the paper binding tool 1 wound in a roll shape on a bobbin or the like into an appropriate length.

  That is, the laminated paper 101 is a belt-like paper wound in a roll shape, and continuously cuts one side portion of the laminated paper 101 into a comb-like shape and further shapes it into a curved shape. The ring portions 2, 2... Connected to the strip-shaped paper pieces can be configured. And since it is a strip-shaped paper piece having a plurality of continuous ring portions 2, 2..., The range of the number of continuous ring portions 2. Compared with the strip-shaped one having the ring portions 2, 2..., The ring portions 2, 2. .. Can be arbitrarily determined when binding a plurality of sheets 51, 51..., So that it is possible to easily cope with sheets 51 of all sizes in a large variety and small quantity production.

  In this way, the paper binding tool 1 is composed of the laminated paper 101 configured by laminating paper sheets, and has a bonding layer 2d between the paper sheets and is continuously provided along the extending direction. And a plurality of tooth-like portions (ring portions 2, 2...) Extending in one direction orthogonal to the extending direction from the connecting portion, and the connecting portion is the ring portion 2. 2 is an end portion opposite to the extending side, and between the sheets of the laminated paper 101 in the connecting portion is bonded along the extending direction, and the ring portions 2 and 2 Since the adhesive layer 2d is exposed at the tip of the paper, the necessary number of the ring parts 2, 2 ... need not be set in advance before the paper binding tool 1 is produced. When the binding tool 1 is produced, the paper binding tool 1 can be produced by arbitrarily selecting the number of the ring portions 2. Therefore, the paper binding tool 1 having the ring portions 2, 2... Capable of binding sheets 51, 51. Can be provided.

  In addition, a plurality of continuous ring-shaped portions are formed by bending a two-ply laminated sheet 101 having a substantially band-like room (band-like room part 3) on one end side and the other end side being cut into a substantially comb-like shape by curving into a cylindrical shape. In the paper binding tool 1 formed to include (ring portions 2... 2), the laminated paper 101 has an adhesive layer on one facing surface of the laminated paper 101 and has the adhesive layer. The laminated paper is the outer peripheral side (outer paper 2a), and the laminated paper 101 on the inner peripheral side (inner paper 2b) is the outer paper 2a at the tip (flat portion 2c) of the laminated paper 101 cut into a comb shape. The adhesive layer 2d of the laminated paper 101 of the outer paper 2a is exposed at the flat portion 2c, which is shorter than the laminated paper 101, and is cut into a comb-teeth shape (flat portion 2c) of the laminated paper 101, and the belt-like margin Fold both sides of the section 3 outward from the curved surface Since each flat part is molded, when binding the tip part of the ring part 2, it is not necessary to apply an adhesive or the like to the opposite surface of the flat part 2c again. 3 can be press-bonded.

[Manufacturing process of paper binding tool 1]
Next, the outline of the manufacturing process of the paper binding tool 1 according to the present invention will be described with reference to FIGS. 4 and 5.
The manufacturing process of the paper binding tool 1 is mainly constructed by the first process W01 to the sixth process W06. The application process (first process W01) and the interleaf / comb-like cutting process (second process W02) are sequentially performed. , A half-cut process (third process W03), a rewinding process (fourth process W04), a molding process (fifth process W05), and a bookbinding process (sixth process W06).

  The application step (first step W01) is a step of applying an adhesive (heat sealant) to one surface of the strip-shaped paper 100 wound in a roll shape. In this embodiment, as shown in FIG. The heat sealing agent is continuously applied to the lower surface side of the belt-like paper 100 fed out from the bobbin. The belt-like paper 100 to which the heat sealing agent is applied is then wound around a bobbin with the application surface facing inward, and is conveyed to the next slip-sheet / comb-like cutting step (second step W02).

  In the interleaf / comb-like cutting step (second step W02), the belt-like paper 100a to which the heat sealing agent is applied in the coating step and the belt-like paper 100b to which the heat sealing agent is not applied are continuously laminated and bonded. Then, it is a step of cutting one side portion into a comb-teeth shape.

  That is, as shown in FIG. 5 (b), the belt-like paper 100a to which the heat sealing agent drawn from the bobbin has been applied is guided with the application surface facing upward, and at the same time, the belt-like paper to which the heat sealing agent has not been applied is applied. The paper 100b is pasted.

  Thereafter, heat is applied to both the left and right ends of the bonded strip-shaped paper 100 (hereinafter, the strip-shaped paper 100 bonded by the slip sheet process (second process W02) is referred to as “laminated sheet 101”). The adhesive state of the left and right end portions excluding the central portion is firmly established, and a comb-like cut is made in the central portion of the laminated paper 101.

  By taking such a process, two comb-like laminated papers 101R and 101L can be formed from one laminated paper 101, and the comb-like part cut into the central portion ( In the comb-like portion), an unbonded state can be maintained. That is, in the application step (first step W01), the heat sealant is applied only to the left and right ends of the belt-like paper 100, and in the state of the laminated paper 101, the central portion is in an unbonded state. It is. In addition, by making the said comb-tooth-shaped part into an unadhered state, the ring part 2 * 2 ... formed after that can be made into an unadhered state, and a ring part 2 * 2 ... can be easily formed into a curved shape. The two formed comb-like laminated sheets 101R and 101L are then divided, wound around the bobbin again, and conveyed to the next half-cut process (third process W03).

The half-cut process (third process W03) is a process of removing one of the upper and lower laminated sheets 101R (or laminated sheet 101L) at the tip of the comb-like portion of the laminated sheet 101.
That is, as shown in FIG. 5C, the laminated paper 101R (or the laminated paper 101L) cut in the comb-teeth shape by the interleaf / comb-like cutting step is the side to which the heat seal agent is applied (laminated paper). 101a) is drawn from the bobbin with the bottom surface, and the top end 101c of the comb-like portion is cut and removed from the laminated paper 101b on the top surface side. Thereafter, the sheet is wound around the bobbin again, and one laminated sheet 101R (or laminated sheet 101L) is conveyed to the next rewinding process (fourth process W04), and the other laminated sheet 101L (or laminated sheet 101R) is It is conveyed to the molding step (fifth step W05).

  The rewinding step (fourth step W04) is a step for rewinding the bobbin again in order to unify the state wound on the roll in one direction with respect to one of the comb-like laminated sheets 101 formed at the same time.

  In other words, in the interleaf / comb-like cutting step (second step W02), two comb-like laminated papers 101R and 101L are formed from a single laminated paper 101. Since it is molded and then wound around the bobbin in the same direction, the extending directions of the comb-like portions are opposite to each other and wound in a roll shape.

  Therefore, in order to unify the extending direction of the comb-tooth-shaped portion to either one, the one laminated paper 101R (or laminated paper) cut into the bobbin again in the bobbin by the rewinding process (fourth process W04). 101L) is rewound. Note that the laminated paper 101R (or the laminated paper 101L) wound around the bobbin by the rewinding process (fourth process W04) is conveyed to the next molding process (fifth process W05).

  The forming step (fifth step W05) is a final step of bending the comb-like portion of the laminated paper 101 into a ring shape, and is composed of two work steps as described later, and is continuous as shown in FIG. 5 (d). This is a step of forming a simple paper binding tool 1.

  In the bookbinding step (sixth step W06), as shown in FIG. 5 (e), the paper binding tool 1 continuously formed by the forming step (fifth step W05) is cut to a predetermined length (number of rings). Is a step of actually binding a plurality of sheets 51.

  That is, the ring-shaped comb teeth portion is inserted into the binding holes 51a, 51a,... Of the plurality of sheets 51, 51. The paper binding tool 1 is bound by crimping the band-shaped margin 3.

  The paper binding tool 1 is continuously formed by taking the above-described plural steps (first step to sixth step), and according to the size of the sheets 51, 51,. If necessary, it can be cut by a necessary length.

[Coating process (first process W01)]
Next, details of the coating process (first process W01) will be described with reference to FIG.
The application step (first step W01) is a step of applying an adhesive (heat sealing agent) to one side of the belt-like paper, and mainly a feeding device that adjusts the feeding speed of the belt-like paper 100 wound around the bobbin 7. 4, a coating device 5 that actually applies the heat sealant to the belt-like paper 100, and a winding device 6 that winds the belt-like paper 100 that has been processed by the coating device 5 around the bobbin 17 again.

  The feeding device 4 includes a frame 8 that supports both ends of the pivot shaft of the bobbin 7 as a skeleton, and a feeding unit 9 that sets the bobbin 7 at a predetermined position. The input unit 9 includes input arms 9b and 9b pivotally supported on the lower portion of the frame 8, a drive motor 9a serving as a power source for the input arms 9b and 9b, and a drive motor 9a on the input arms 9b and 9b. It is comprised by the drive chain 9c etc. which transmit this rotational driving force.

  Two throwing arms 9b and 9b are arranged in parallel on the left and right sides with the frame 8 in between when viewed from the front, and both members 9b and 9b are inserted through a rotating shaft that is fitted at a right angle at one end. Are concatenated.

  Here, a sprocket is inserted into one end of the rotating shaft, and the sprocket is connected to a drive motor 9a via a drive chain 9c. In addition, in both the input arms 9b and 9b, a substantially U-shaped member is provided at the tip portion on the side facing the rotation shaft, and the pivot shaft of the bobbin 7 is held by this member. The

  By using the insertion portion 9 having such a structure, the bobbin 7 can be easily set on the frame 8. That is, in the initial state (before the bobbin 7 is thrown into the frame 8), the throwing arms 9b and 9b lie in the horizontal direction around the rotation axis provided at the rear lower end of the frame 8, but the "U" When the pivot shaft of the bobbin 7 is set on the character member and a switch (push button switch) (not shown) is inserted, the drive motor 9a starts to be driven, the input arms 9b and 9b are raised, and the bobbin 7 is set to the installation position. It is carried to.

  The belt-like paper 100 is drawn out from the bobbin 7 set on the frame 8, changes its traveling direction through a plurality of rollers, and is guided to the coating device 5 described later.

  Here, a gear (not shown) is fitted into one end of the pivot shaft of the bobbin 7, and a torque transmission mechanism (not shown) is provided on the frame 8. Even if the belt-like paper 100 is forcibly fed out by the coating device 5 by setting the bobbin 7 at a predetermined position of the frame 8 and applying a torque in the direction opposite to the feeding direction to the bobbin 7, The paper 100 does not slack.

  The torque transmission mechanism uses an electromagnetic clutch in this embodiment, but is not limited to this. For example, a torque transmission mechanism using a strong torsion spring or the like may be used.

  The coating device 5 mainly includes a coating unit 10 that applies a heat sealant to one side of the belt-like paper 100 fed from the feeding device 4, drying units 11 and 11 that dry the heat-sealant, and a belt-like paper 100 that has finished drying. And a cooling unit 12 that performs centralized cooling to room temperature (outside air temperature).

  Two rollers 13 and 13 that are adjacent to each other in the vertical direction are rotatably provided in the coating unit 10, and a substantially rectangular tray 15 is disposed below the (rollers 13 and 13). A liquid adhesive (heat sealant) is placed in the tray 15, and the lower part of the lower roller 13 is in contact with a roller whose lower part is immersed in the heat sealant.

  Then, the belt-like paper 100 fed out from the feeding device 4 changes its traveling direction through a plurality of rollers provided on the coating device 5 side, and is guided between the rollers 13 and 13. A heat sealant is applied to one surface.

  That is, the rollers 13 and 13 of the coating unit 10 are in contact with each other on the front surface and the back surface of the belt-like paper 100, and the rollers 13 and 13 are rotated by pulling out the belt-like paper 100. Then, when the lower roller 13 rotates, the heat sealant attached to the lower surface is carried to the upper portion and attached to the back surface of the belt-like paper 100.

  The drying units 11 and 11 are arranged in two parts along the traveling direction of the belt-like paper 100, are provided immediately after the coating unit 10, and a plurality of hot air outlets are arranged along the traveling direction. . In other words, the belt-like paper 100 that has passed through the application unit 10 passes through the drying units 11 and 11, whereby the solvent of the heat sealant attached to the back surface evaporates and is reliably attached to the back surface of the belt-like paper 100. The reason why the drying units 11 and 11 are provided in two parts is because of the transportation mode of the entire apparatus, and is not limited to this, and may be configured as an integral structure.

  The belt-like sheet 100 that has passed through the drying units 11 and 11 is then guided to the cooling unit 12. Here, the cooling unit 12 is provided immediately after the drying unit 11, and, like the drying units 11 and 11, a plurality of cold air outlets are arranged along the traveling direction to Cooling.

  By passing through the cooling unit 12, the heat sealant applied to the belt-like paper 100 is cooled and loses its adhesiveness. Therefore, even if it is rolled again by the winding device 6 described later, it does not adhere to each other. .

  In addition, a pinch roller unit 30 is provided on the downstream side of the cooling unit 12. A driving force is applied by the pinch roller unit 30, and the belt-shaped paper 100 is fed out. That is, the pinch roller unit 30 is configured by two rollers or the like adjacent in the vertical direction, and when one of the rollers is driven and rotated, the belt-like sheet 100 sandwiched between the two rollers is fed downstream. .

  The winding device 6 has a rotating shaft 6a having a cantilever structure, and an empty bobbin 17 is fitted into one end thereof, and a rotation driving unit (not shown) is provided at the other end. . Then, the belt-like sheet 100 fed out by the pinch roller unit 30 is again wound around the empty bobbin 17 by the winding device 6 in a roll shape.

  As described above, the belt-like sheet 100 fed from the feeding device 4 sequentially passes between the application unit 10, the drying units 11 and 11, the cooling unit 12, and the pinch roller unit 30 of the coating device 5, and then wound. It is guided to the take-up device 6 and taken up again in a roll shape.

Is constituted by a comb-like cutting step for continuously cutting into a comb-like shape.

  Here, the interleaf process is composed of an unwinding device 18 that holds the two strip-shaped papers 100, 100 wound in a roll shape, and an interleaf device 19 that presses the two strip-shaped papers 100, 100 together. In the comb-tooth cutting step, the comb-tooth cutting device 20 that continuously inserts a comb-tooth-like cut into the center of the laminated paper 101, and the division that separates the laminated paper 101 separated by the comb-tooth cutting device 20 The apparatus 21 and a winding device 22 that winds each separated laminated sheet 101 around a bobbin are configured. These steps are arranged in order from the upstream side to the interleaving step and the comb-like cutting step, and absorb the difference in processing time by using the slack detection device 23 provided between the two steps as described later. To do.

  The unwinding device 18 is composed of two bobbin receiving bases 18a and 18b, and is arranged in a straight line along the traveling direction of the belt-like sheets 100 and 100 and slightly shifted from each other in the vertical direction. . The bobbin receiving bases 18a and 18b are formed by a rectangular box whose longitudinal direction is the traveling direction of the belt-like sheets 100 and 100, the upper surface thereof is open, and the lateral width (short direction) is the width of the bobbins 17 and 17. It is provided slightly larger than. Therefore, in order to set the belt-like sheets 100 and 100 wound around the bobbins 17 and 17 on the bobbin receiving bases 18a and 18b, the bobbins 17 and 17 are respectively inserted from the open portions on the upper surface, and after the insertion, A fall of the box is prevented.

  In addition, two freely rotatable rollers are provided in the center of the inside lower part of the bobbin receiving bases 18a and 18b. The rollers are circumscribed by the belt-like papers 100 and 100 set on the bobbin receiving bases 18a and 18b. Holds free rotation when 100 is fed.

Is provided.

  An upper transport belt 29 is provided in the vicinity of the upper plate 27 so as to surround the upper and lower sides. When the lifting frame 25 is lowered, the lower surface of the upper transport belt 29 and the upper surface of the lower transport belt 28 come into contact with each other. It is like that. Note that the travel directions of the upper transport belt 29 and the lower transport belt 28 both coincide with the travel direction of the belt-shaped paper 100.

  When the two overlapped belt-like papers 100, 100 are guided to the interleaf device 19 having such a configuration, the belt-like papers 100, 100 are first moved to the upper conveying belt 29 by the elevating frame 25 being lowered. And the lower conveying belt 28, and then the upper plate 27 is lowered, whereby the ends of the belt-like sheets 100 and 100 are heated and the upper and lower belt-like sheets 100 and 100 are pressure-bonded.

  The crimping operation of the strips 100 and 100 is performed continuously. When the crimping operation is stopped, only the upper plate 27 rises in the elevating frame 25, and excess heat is applied to the strips 100 and 100. Is configured to prevent transmission.

The locations where the belt-like sheets 100 are pressed are limited to some regions on both the left and right sides except for the central portion in plan view. Then, the upper and lower plates 26 and 27 press the belt-like sheet with the respective conveying belts 28 and 29 interposed therebetween.

  The comb-tooth cutting device 20 includes a pinch roller unit 31 that pulls in the laminated paper 101 (that is, two upper and lower belt-like papers 100 and 100 laminated and bonded by the interleaf paper device 19), and a comb-teeth-shaped cutting device 20 at the center of the laminated paper 101. It is composed of a press section 32 and the like for cutting.

  The pinch roller unit 31 is provided on the upstream side of the press unit 32, and is mainly configured by two rollers or the like adjacent in the vertical direction, and is sandwiched between the two rollers by driving and rotating one of the rollers. The laminated paper 101 is fed downstream.

  The press portion 32 includes a base frame 32a formed in a rectangular table shape, a lower frame 32b provided freely in the vertical direction at a lower portion on the downstream side of the base frame 32a, and a lower frame 32b on the upper surface of the base frame 32a. The upper frame 32c and the like are disposed above.

  As shown in FIG. 8, a cutting blade 33 (Thomson blade) is detachably disposed on the lower surface of the upper frame 32 c, and the lower frame 32 b rises by leading the laminated paper 101, whereby the laminated paper 101. A comb-like incision is made in the center of the.

  Here, as shown in FIG. 8, the cutting blade 33 is provided with a belt-like blade 35 standing upright on the wooden board 34 while drawing a sine curve at the center of the plane of the rectangular wooden board 34. Around the periphery, there is provided a rubber plate 36 having such a thickness as to substantially hide itself (blade 35).

  Further, the tip positions on both sides of the blade 35 are slightly shifted. Specifically, in FIG. 8, the tip position on the upstream side (right side in FIG. 8) is on the X1 line, and the downstream side (in FIG. 8). Since the tip position on the left side is formed on the X2 line, an overlap amount of dimension a is provided at the tip portions on both sides. By having such a configuration, the cutting blade 33 can surely add a continuous “cut” to the central portion of the laminated paper 101. In other words, since the positions of the tip portions on both sides of the blade 35 are overlapped in advance, even if some deviation occurs in the left and right sides in the transport direction, a continuous smooth cut is formed as long as it is within the dimension a. Can do it.

  9A, a rubber plate 36 is provided around the blade 35. When the blade 35 cuts into the laminated paper 101, the lower surface of the rubber plate 36 is always applied simultaneously with the blade 35. Then, as shown in FIG. 9B, the blade 35 then cuts into the laminated paper 101 while compressing the rubber plate 36. When the blade 35 cut from the laminated paper 101 is pulled out, the laminated paper 101 is pressed against the cut blade 35 in order to press the laminated paper 101 while the compressed rubber plate 36 is elastically deformed downward. 101 can be reliably pulled out without being caught.

  A looseness detecting device 23 is provided between the interleaf device 19 and the comb-tooth cutting device 20, and the looseness of the laminated paper 101 occurring between the devices 19 and 20 is detected to detect the appropriateness of the laminated paper 101.

  That is, when the feeding speed of the pinch roller unit 31 provided in the comb-tooth cutting device 20 is slower than the conveying speed of the conveying belts 28 and 29 provided in the interleaf device 19, the laminated paper 101 is interposed between both devices 19 and 20. If this amount of slack is large, the laminated paper 101 may be bent. Therefore, when the slack of the laminated sheet 101 exceeding a predetermined level occurs, the detection is performed by the detector 23a, and the feeding speed of the pinch roller unit 31 is increased, or the conveyor belts 28 and 29 are increased. The appropriate conveyance state of the laminated paper 101 is maintained by decelerating the conveyance speed.

  The dividing device 21 is a device that separates the laminated paper 101 divided into two parts by the comb-tooth cutting device 20, and a tension that absorbs the slack of the laminated paper 101 generated between the comb-tooth cutting device 20 and the dividing device 21.

  The tension portion 37 includes a moving frame 37a that can slide in the vertical direction and an idler 37b that is pivotally supported in a direction perpendicular to the moving frame 37a. The laminated paper 101 fed from the comb-tooth cutting device 20 is an outer periphery of the idler 37b. After passing through the lower part of the surface, it is led to a pinch roller part 38 to be described later.

  And about the relative relationship of the feeding speed of each pinch roller part 31 * 38 provided in the comb-tooth cutting device 20 and the dividing device 21, for example, if the feeding speed on the dividing device 21 side is high, the idler 37b If the feeding speed on the dividing device 21 side is slow, the idler 37b is lowered to always apply an appropriate tension to the laminated paper 101 in the region sandwiched between the two pinch roller portions 31 and 38. Therefore, the slack of the laminated paper 101 generated between the two devices 20 and 21 can be removed.

  The pinch roller unit 38 is configured by two rollers or the like adjacent in the vertical direction. When one of the rollers is driven and rotated, the laminated sheet 101 sandwiched between the two rollers is fed downstream. Then, the fed laminated sheet 101 is divided into two parts on the left and right sides, and is conveyed upward and downward by a plurality of rollers 39.

  The winding device 22 is composed of two rotating shafts 22a and 22a having rotational driving, and empty bobbins are set on the rotating shafts 22a and 22a, and two sheets of laminated paper 101 and 101 fed from the dividing device 21 are loaded. Each is wound around the empty bobbin.
