DEVICE FOR TRANSFER AND CUTTING OF SHEET MATERIAL HAVING SURFACE SUPPORTED BY SUCTION OF VACUUM PRESSURE

摘要

PURPOSE: To surely minimize the inflow of the outside air to a vacuum layer formed under a support surface with the low cost by mounting a sealing means for sealing a side surface of a knife-edge penetration permission layer of a conveyor segment. CONSTITUTION: The end rotary units 22, 24 are driven to move a conveyor, a multilayered sheet material 18 is properly positioned to a cutter head, and vacuum pump 48 is started to form a vacuum layer in the bristle of the conveyor segment 60. A control unit simultaneously starts a driving cylinder 164 for moving a first seal assembly 168 and a second seal assembly from a refused position to a sealing position. Whereby the first seal assembly 168 moves upwardly, and the second seal assembly is brought into contact with an exposed bottom surface of the conveyor segment 60 projecting from a vacuum duct 54 toward an end part 109 of an upper conveyor section 26.
