During the advance and after the end position has been reached, a winding band (18) is maintained by pneumatic means in a loop form determined essentially by the sliding surface (16), during the band pull-back is drawn out of the band guide (12) without the movement of any mechanical parts and is laid round the packaging articles. The band guide (12) with the sliding surface (16) and lateral guides (36, 38) for maintaining the winding band (18) in a loop form has exclusively pneumatic means. (Figure 2)
