Abstract
Method comprises forming >=2 tubular film strips from a flattened tubular film strip of a single - or double layer strip of film by longitudinal cutting and longitudinal weld seams, forming side pleats in the tubular film strips and carrying out transverse bottom seaming, and bag-separating as well as bag-opening separating cuts. After forming the longitudinal weld seam and longitudinal cut, the subdivided tubular films are transported in different planes relatively to each other overlapping the doubled side pleat width and are brought back into one plane and closely side by side, after inserting the side pleats and before reaching the transverse welding and cutting station.
