Continuous stacking of sheets

摘要

When a main stack 1 is to be withdrawn, it is lowered and one or more wedges 12 are rotated about shaft 6 until they lie on top of the stack to form between the stack and subsequently arriving sheets 4 a space into which a rake 14 is inserted. Further lowering and withdrawal of the stack permits the wedge(s) to assume normal rest position (pointing vertically downwards). A new pallet is brought up to the level of the rake 14, which is then retracted. A sheet catcher 10 may be inserted during the initial stage of stack withdrawal.
