Abstract
It is aimed to provide a composite sheet manufacturing device and a composite sheet manufacturing method capable of maintaining high cutting performance of a cutter by suppressing the adhesion of an adhesive of an adhesive surface to the cutter. A first sheet (42) introduced to between a cutter roller (2) and an anvil roller (3) is cut into strips (42a) while these rollers (2, 3) are rotated relative to each other, adhesive surfaces (a) of the strips (42a) are adhered onto a second sheet (43) for compounding, and at least one of a cutter (12) of the cutter roller (2) and the anvil roller (3) is cooled by a refrigerant by a cooling unit (20, 21).
Claims9
A composite sheet manufacturing device for compounding strips produced from a first sheet and a second sheet, the first sheet having an adhesive surface, the device comprising:
- a cutter roller configured to rotate about a predetermined axis and including a cutter;
- an anvil roller configured to cut the first sheet into strips by introducing the first sheet to between the cutter roller and the anvil roller by rotating relative to the cutter roller;
- and
- a cooling unit configured to cool at least one of the cutter of the cutter roller and the anvil roller by a refrigerant.
A composite sheet manufacturing method for compounding strips produced by cutting a sheet-like first sheet having an adhesive surface and a sheet-like second sheet, comprising:
- a cutting step of cutting the first sheet between a cutter provided on a cutter roller and an anvil roller to produce the strips by introducing the first sheet to between the anvil roller configured to rotate about a predetermined axis and the cutter roller configured to rotate relative to the anvil roller about a predetermined axis;
- and
- a cooling step of cooling at least one of the cutter of the cutter roller and the anvil roller by a refrigerant, the cooling step being performed at least during the execution of the cutting step.
