An adhesive application device, preferably in a tube extruding machine, for transferring adhesive to a sizing roller using an adhesive transfer roller that is mounted with bearings in lever arms so that it can rotate. The adhesive transfer roller can be moved toward and away from the sizing roller using the lever arms which are mounted so that they can rotate in the machine frame. The bearings, with which the adhesive transfer roller is mounted in the lever arms are accessible from the outside of the machine frame side walls so that the bearings can be replaced without removing the transfer roller from its position between the side walls.

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.
