Abstract: 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.

Abstract: The invention relates to an adhesive transfer roller (1) of an adhesive application device, preferably in a tube extruding machine, to transfer adhesive to a sizing roller, whereby the adhesive transfer roller (1) is mounted with bearings in lever arms (6, 10) so that it can rotate, it being possible to use these lever arms (6, 10) so that the adhesive transfer roller (1) can be moved toward and away from the sizing roller and whereby the lever arms (6, 10) are mounted so that they can rotate in the machine frame, beyond the side walls (2) of which the adhesive transfer roller (1) extends. The invention is characterized in that the bearings (5), with which the adhesive transfer roller (1) is mounted in the lever arms (6, 10), are accessible from the outside of the machine frame side walls (2).

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.
