ABSTRACT:
The welding frame (3) of a film-welding device (2) is at the start of its pivoting movement motor-driven in positive manner over a few radians and is then released from the drive, so that only on the basis of its flywheel energy and weight force is it moved on to the locked closed position. Thus, accident risks can be avoided without separate control means, because for stopping the welding frame (5) it is essentially only necessary to dissipate the relatively low flywheel energy.
