A guide mandrel adapted for positioning and intermittently positively moving a tube, mounted on a common frame of the apparatus, is hollow and has a port on the side of a charging pipe telescopically connected with a means adapted for cutting through the tube wall, with such means being a movable continuation of the charging pipe and connecting the latter via the cut in the tube wall and the port with the hollow of the mandrel in the course of filling a sack.
