Abstract
An apparatus for stacking double bags, which have been severed by hot-wire welding from a tubular web of plastic and have opening-defining edges adjacent to their center line, includes a wicketer having a horizontal shaft and pairs of juxtaposed spokelike radial feeding arms which are axially spaced apart and secured to the shaft and are provided with means for retaining the double bags. Stacking pallets provided with upstanding stacking pins are slidably movable between the feeding arms, by which the double bags are deposited on the pallets, e.g., on needles provided on the pallets. To permit a trouble-free stacking of the objects without an intermediate stacking and without an interruption of the manufacturing process, a pallet-handling member for guiding and retaining stacking pallets is provided, which extends approximately radially with respect to the shaft and is pivotally movable about the shaft and in a first position delivers a stacking pallet to a pallet holder, which is movably mounted on the shaft, and in a second position removes the pallet from the pallet holder and then moves the pallet to a stack-removing device.
