Abstract
A conveyor system for transporting a succession of thin flexible sheets such as plastic bags from a bag forming device to a bag stacking device. The conveyor system includes a first conveyor having vacuum holes for holding the bags in place, with portions of the bags extending beyond the conveyor's edges. The system further includes bag support apparatus such as a pair of auxiliary conveyors located alongside the first conveyor and supporting the overhanginig portions of the bags. The auxiliary conveyors terminate short of the end of the first conveyor, such that for a predetermined distance the overhanging portions of the bags are unsupported, thus permitting a bag stacking device to lift the bags and deposit them onto a stack.
