A cylindrical tube provided with a longitudinal seam is formed in a tubular bag machine from a flexible film unwound from a roll. The filling material (15) is filled into the tube in weighed quantities. Bags (13) are formed by means of transverse seams (21). In order to compress the bag contents before forming the top seam, spring-suspended stripper jaws (7) are present, which are associated with transverse sealing jaws (3). During stripping, the stripper jaws (7) are pressed against the tube (2), which is moved downwards continuously, and moved downwards with a speed which is high in relation to the tube advance. Subsequently, the top seam is produced on the bag (13) by pressing the transverse sealing jaws (3) together. As a result of this, the bag contents - for example potato crisps - can be compressed in a particularly simple manner and thus the consumption of tube material reduced. <IMAGE> |
