A flow pack machine has at least two transverse sealing jaws, which are arranged on opposite sides of a film tube to be sealed on in each case one jaw carrier, which revolves cyclically at least approximately on circular paths and can be engaged on and separated from one another, the jaw carriers being in each case mounted in rotary manner on at least one guide rod and the latter is fixed to a rotary shaft mounted in a bearing wall. There is also a first toothed belt wheel (19, 19'), traversed by the rotary shaft (15, 15'), located on the bearing wall (17), and a second toothed belt wheel (12, 12') fixed to the jaw carrier (7, 7') and which are interconnected in rotation by means of an endless, closed toothed belt (20).
