Abstract

1. Method for forming a longitudinal welding or sealing seam on the jacket of a tube of foil in a tubular bag-making machine, whereby a welding or sealing head (7) is moved at the same speed as the tube (5) along a predetermined path in contact with the jacket and thus generates the welding or sealing seam, whereby the welding or sealing head (7) is subsequently raised off the tube (5) and is returned to the initial starting position, whereby the next welding or sealing seam is applied to the tube (5) so that it overlaps the first for a short distance, characterised by the fact that the tube (5) is moved continuously along its axis by a mechanism in contact with the jacket of the tube and the welding or sealing head (5) is driven by its own drive mechanism during the welding or sealing process and its return run.
