PROCESSING DEVICE OF IRREGULAR COMPOSITE SHEET AND MANUFACTURING METHOD OF IRREGULAR COMPOSITE SHEET

摘要

PROBLEM TO BE SOLVED: To provide a processing device of irregular composite sheets, which can reduce a risk of mixing of a contaminant of a roll and can improve the productivity.SOLUTION: A processing device 1 of irregular composite sheets includes a center roll 10 having an irregularity processing part 13 of a sheet to be transferred, which is formed by disposing a plurality of projecting bar parts 12 in a roll peripheral direction at a definite distance in a roll width direction and an engagement part 14 of the sheet disposed on both sides of the irregularity processing part 13 on a roll peripheral surface 10S, an indentation roll 20 having indentation projection bar parts 22 connecting in the roll peripheral direction on a roll peripheral surface 20S, a seal portion 32, and an anvil roll 30, the anvil roll 30 being provided with a heating means 41, the center roll 10 and the anvil roll 30 making an irregularity imparted sheet by the center roll 10 and the indentation roll 20 and both end parts of the sheet correspond to step parts 33, 34, and by isolating both side portions from the step parts 33, 34 to seal the sheet between the irregularity processing part 13 and the seal part 32.SELECTED DRAWING: Figure 1
