Document Type and Number:
Japanese Patent JP7448574
Kind Code:
B2
Abstract:
To provide a technology capable of stably manufacturing a composite sheet having a through-hole by preventing contamination of an apparatus by a cut-piece of a sheet generated when the through-hole is formed by cutting the sheet.SOLUTION: A manufacturing method of a composite sheet has a post-processing step of cutting off a cut-piece of a sheet connected to a vicinity of a through-hole 5 in a composite sheet 1 manufactured in a composite sheet manufacturing step. In the post-processing step, the composite sheet 1 is transported while a surface to be processed of the composite sheet 1 is brought into contact with peripheral surfaces of a first transport roll 21 and a second transport roll 22 in the order to cut off the cut-piece from the composite sheet 1. In the post-processing step using the second transport roll 22, the roll 22 is rotated at a peripheral speed equal to or higher than a transport speed of the composite sheet 1.SELECTED DRAWING: Figure 3
