The packaging machine has a pair of rotating shafts (10, 11) with radially projecting plates (6, 7; 8, 9), provided at their ends with welding and separating devices, e.g. glow plugs or heating wires, for the plastics packaging film. The ends of one of the rotating shafts (10) are each received by one arm (51a, 52a) of a pivoted angle lever (51, 52) which has a second lever arm (51b, 52b) cooperating with a position setting device (60), providing a counter-force which is adjustable during the operation of the machine. |
