- the width W A1 of the application execution area A1 is determined by the width of the supply port 35X formed in the chamber 35C, here, as shown in FIG. 6, the two masks member 39M to align in the width direction sides of the transport path R, the width W A1 of the application execution area A1 is narrower than in the case of not using the mask member 39M.
- the width direction of the transport path R is a direction orthogonal to the transport direction.
- the delivery device 10 sequentially sends out the sheets S to the conveyance path R (see FIG. 2).
- the sheet locking control unit 22 has a sheet locking tool 21 between the locking execution state (see FIG. 4A) and the locking release state (see FIG. 4B). Are switched at a predetermined timing. Accordingly, the plurality of sheets S sequentially sent out from the sending device 10 are partially overlapped and conveyed to the coating device 30.

- the position change control unit 37 keeps the relative positions of the roll 31 and the roll 32 at the application retracted position (see FIG. 5).
- the position change controller 37 moves the backup roll 31 closer to the conveyance path R and sets the relative positions of the roll 31 and the roll 32. Then, the application switching position (see FIG. 5) is switched to the application possible position (see FIG. 3A).
- the rotation of the backup roll 31 moves the circumferential surface of the backup roll 31 in the application execution area A ⁇ b> 1 in the same direction as the conveyance direction of the sheet S, so the sheet S is conveyed in the conveyance direction.
- the peripheral surface of the coating roll 32 in the application execution area A ⁇ b> 1 moves in the direction opposite to the conveying direction of the sheet S.
- the coating unit 35 supplies the adhesive C to the rotating coating roll 32.
- the adhesive C coming out of the supply port 35X is filled in a groove formed on the peripheral surface of the coating roll 32, and approaches the transport path R by the rotation of the coating roll 32.
- the adhesive C filled in the groove of the coating roll 32 is transferred to the sheet S in the application execution area A1.
- a groove 32S that can be filled with the adhesive C is formed on the peripheral surface 32A of the coating roll 32, so that the adhesive C supplied from the coating unit 35 has a bottom 32SB and an opening 32SX. And both are filled.
- the adhesive C filled in the opening 32SX is transferred to the sheet S, but is filled in the bottom 32SB.
- the adhesive C is not transferred to the sheet S and remains filled in the bottom 32SB.
- the adhesive applied to the coating roll is applied to the sheet as it is.
- the amount applied to the coating roll (the thickness of the coating film) remains as it is of the sheet S. It will be thick. As a result, it is very difficult to perform thin coating (for example, the thickness of the coating film is 10 ⁇ m or less).
- the coating amount of the sheet S is likely to fluctuate depending on the rotation speed of the coating roll.
- the application amount of the adhesive C can be adjusted depending on the physical properties of the adhesive C, the formation density of the openings 32SX on the peripheral surface 32A, and the like.
- the formation density of the openings 32SX can be adjusted by the shape and formation density of the grooves 32S. Therefore, when the coating roll 32 having the grooves 32S is used, the adhesive C can be thinly applied to the sheet S more easily than the conventional one. Further, it is not necessary to control the coating roll 32 at a high rotational speed in order to adjust the coating amount on the sheet S.

- the film sending machine 51 sends out the belt-like film F.
- the crimping machine 52 bonds the belt-like film F sent out from the film sending machine 51 to the sheet S coated with the adhesive C.
- a plurality of sheets S that are partially overlapped by bonding with the belt-like film F are continuous (see FIG. 7A). In this way, a laminate T in which the partially overlapping sheet S and the film F are integrated is obtained.
- the cutting machine 61 cuts the film F at the cutting position set by the cutting position setting machine 62.
- the laminated body T in which the partially overlapped sheet S and the film F are integrated by cutting the film F becomes a workpiece U in which the individual sheets S and the cut film F are integrated (see FIG. 7 (B)).
- the aligner 71 stacks the workpieces U so that the ends of the individual workpieces U are aligned (see FIG. 8).
- the punching machine 72 collectively performs the punching process on the plurality of workpieces U whose ends are aligned by the cutting machine 61.
- the laminated body L (refer FIG. 1) stamped by the desired shape can be obtained.
- the front side of each sheet S (the downstream side in the transport direction) is a protruding portion V that protrudes from the film F, so that the film F does not get in the way when the front ends of the sheets S are aligned.
- the upstream sheet S0 preferably overlaps the reference sheet S1 as an aspect of the partially overlapping sheet S.
- the rear side (upstream side in the conveyance direction) of each sheet S projects from the film F. Since the portion V is formed, the rear ends of the sheets S may be aligned.
- the adhesive C is applied to the partially overlapped sheet S using the coating roll 32 that moves in the direction opposite to the conveying direction of the sheet S (see FIG. 3A), uneven coating (for example, The adhesive C can be applied without generating the above-mentioned streaks of the adhesive C). For this reason, air does not remain between the sheet S and the film F in the partially overlapping state in the laminate T, and finally, in the laminate L, it is possible to suppress appearance defects due to the adhesive streaks.

- the relative positions of the roll 31 and the roll 32 may be switched by the movement of.
- the adhesive C is not applied to the portion of the sheet S that passes through the application execution area A1 that does not directly contact the coating roll 32 by the mask member 39M.
- an extra adhesive is provided by placing the mask member 39M at a predetermined location. C is not applied to the sheet S.
- the surplus adhesive C does not protrude from the film F.
- the surplus adhesive does not adhere to the side in the width direction when the workpiece U is formed, the ends of the workpiece U can be accurately aligned (see FIG. 8). As a result, it is possible to perform punching alignment with high accuracy.
- an example of the adhesive C is an aqueous synthetic resin emulsion, but the present invention is not limited to this.
- an adhesive composition that does not contain an organic solvent such as an aqueous synthetic resin emulsion can be used as the adhesive C in terms of safety and environmental aspects.
- the water-based synthetic resin emulsion has a higher viscosity than other adhesive compositions. For this reason, when coating is performed using a normal coating apparatus (for example, a coating apparatus in which both the coating roll and the backup roll rotate in the same direction as the sheet S conveyance direction), stringing of the adhesive C occurs. End up.
- the coating roll 32 rotates in the direction opposite to the conveying direction of the sheet S as in the coating apparatus 30, even with the adhesive C having a high viscosity such as an aqueous synthetic resin emulsion, stringing occurs. Hateful. Therefore, by using the coating device 30, the adhesive C can be applied while preventing stringing regardless of the viscosity of the adhesive C.
