In order to produce bags from continuously run film tubes, heated pairs of tools are used, the carriers of which rotate around an axis in such a manner, that they are pressed against each other at the distance of the bag length, acting on the film tube. During the duration of the process the tools run synchronously with the flow of the material. In order to achieve a higher throughput the number of tools used can be raised according to this invention, maintaining the same sealing time by mounting the tools (6,16) correspondingly their carriers (1,11) via cranks (2,12) on drive shafts (3,13 correspondingly 4,14) in a cantilevered manner, i.e. freely sticking out. Through this tools on opposing sides can mesh and be run independently from each other.
