24 are engaged around the looping rollers 20 and are stored in the film storer 11 the looping rollers 20 continue to move around the deflection rollers 22 of the continuous belts 19 so that the looping roller 20 previously on the upper stretches moves to the lower stretches and the looping roller 20 previously on the lower stretches moves to the upper stretches fig5 the looping rollers 20 are moved further along the upper stretches and the lower stretches toward the center of the film storer by corresponding movement of the continuous belts 19 resulting in the position illustrated in fig6 the partial film sections 24 situated or stored in this manner in the film storer 11 have a total length that is considerable and easily enough to reach from the top to the bottom of a relatively tall object or stack 1 after the desired length of film has been stored fig6 the film feeder 8 and the continuous belts 19 are stopped the bars 14 for welding the film section 13 are then closed and the film section 13 is separated from the remaining film 2 by the film blade 12 this is followed by rotation of the rotatable support 7 or the rotation of the guide ring 10 of the rotatable support 7 the rotatable support 7 is advantageously rotated by 90 u00b0 during the welding process and during cooling of the produced weld seam rotation of the support 7 with the storer 22 therefore aligns the stored tube 2 with the crosswise workpiece 1 as shown in fig1 and 2 for the covering operation the film section 13 is opened by the opener 15 or by the suction side plates 16 and as the result of.
