Abstract
Mounted in a frame is a welding cylinder, which is provided with a rotary drive and welding bars, which are distributed at uniform angular distances over the circumference, run parallel to the axis of rotation, can be adjusted continuously in their radial direction by means of their supports, and can be moved in and out in the radial direction relative to their supports for the purpose of activation and deactivation. For the purpose of identifying the respective welding bar, which has executed a specific weld on a film tube passing through, an embossing die, which provides the welded web with a distinct marking, characterizing the welding bar, which has executed the respective weld, is mounted in the circumferential direction in front of or behind each welding bar.
