Abstract
A stack of sheets is formed in a paper cutter by feeding spaced sheets from a first conveyor to a second and slower conveyor to overlap the sheets which are then fed onto a pallet, the latter being lowered as more sheets are fed. When a stack is near completion the first and second conveyors are decelerated and some sheets diverted from the first conveyor to form a gap in the flow of sheets, the second conveyor only is then accelerated for a period of time to enlarge the gap and then decelerate, both conveyors then being accelerated to normal speed. An auxiliary support is then moved into the path of the sheets falling on to the pallet in the gap previously created. While the completed stack is being removed a new stack is forming on the auxiliary support. The full pallet is replaced by an empty one and the auxiliary support is withdrawn to permit the new stack to drop onto the pallet. The gap may be created without diverting any sheets from the first conveyor and the stack may be changed without the use of the auxiliary support.
