<p>The method is of the kind whereby a number of strips of packing material is conducted through a cross section shaping station, through a filling station at which articles are arranged on the strips, through a longitudinally extending welding station at which each strip of material is welded into tube form, through a cross welding station wherein cross welding seams are made between the articles arranged in the packing tubes, and through a separation station for separating the finished packings from the strips of material. In order to obtain registration of the cross welding seams with respect to a pre-printed pattern on the strips of material, the cross welding means are individually controlled as regards their disengagement from the strips of material by means of pulses issued by indication marks arranged along the strips of material and arranged with a pitch corresponding to the length of the packings to be produced. The invention also relates to an apparatus for carrying out the method.</p> |
