ADHESION BREAKER FOR SHEET STACKS

摘要

An apparatus 10 transports sheets of material and breaks the adhesion between first and second sheets 28, 30 when sheets are fed from a stack 14 one at a time. The apparatus 10 includes a gripper 24 which is mounted on a gripper arm 26, 82 and grips the first sheet 28. The arm 26, 82 repeatedly and cyclically moves the leading edge 32 of the first sheet 28 to be fed while the first sheet 28 is held by the gripper 24. The arm 26, 82 moves the leading edge 32 of the first sheet 28 both horizontally and vertically. The vertical cyclical motion causes air pockets to travel between the first and second sheets 28, 30 and the horizontal cyclical motion translates the first sheet 28 relative to the second sheet 30 to break the adhesion.
