ABSTRACT:
Bags for packaging cut tobacco are severed from a continuous longitudinally moving film sheet along transverse welding seams 28 which are made by a thermal welding unit 29 having three, transverse-welding jaws, during each working cycle. The welding unit can be moved to and fro and is movable with the film sheet 25 for a part section (conveying section). During the return movement of the welding unit to its starting position, the film sheet is conveyed onwards by a special draw element, until a conveying cycle has been completed.
