Favored on the slide from the welding device. The carrier 10 is fastened to the clamping jaw 12, which extends the hold-down device, which presses the film in the direction from top to bottom io transversely to the path of movement of the film to be processed, and also extends the cutting 13 in a simplified manner. The clamping jaw is attached to the carrier 11 by the separating knife because it is fastened by this force 14. Both clamping jaws 12 and 14 have exercised the cutting process favored, so that to- at a distance one behind the other equally thick films cut in a simple manner- welding surfaces 15 α and 15 b. Both clamping jaws can be th. 15 are provided with a heating device in the form of

Next to the pair of take-off rollers, between the pressure exerted by the hold-down device on the film, the welding and separating device generates a tension on the film that simplifies the two superposed and cutting them with the knife, where welding device Serving clamping jaws are 65 in the cut part of the film, one of which is pulled out a movable area of the clamping jaws in a groove and has a separating knife arranged there, the upper side cannot be welded, but instead of a clamping jaw on one and Slidable only a bottom seam weld.
