CUT AND SEAL WELDING DEVICE AND METHOD FOR THE JOINING AND SEPARATING OF AREAS OF WELDABLE FOIL WEBS WITH A CUT AND SEAL WELDING DEVICE

摘要

The invention relates to a separating welding device for the area-wise joining and area-wise separation of heat-sealable film webs (2, 3) with a temperature-controllable working surface (4) for supporting film webs (2, 3) to be joined and separated, comprising an electric heating device (11, 12, 13), as well as with an anvil (15) for the partial introduction of compressive forces on the film webs (2, 3), the work surface (4) a variably adjustable working gap (32, 33, 34) limited and the two spaced from each other Joining punches (29, 30) and between the joining punches (29, 30) arranged separating punch (31), wherein the separating punch (31) and / or at least one joining punch (29, 30) are movably received on the counter-holder (15). According to the invention, a force sensor (45) and / or a respective motion sensor (44), in particular a displacement sensor, for determining a separation profile determined by the separating punch (31) are provided to the separating punch (31) and / or the joining punch (29, 30) and / or one of the joining die (29, 30) certain joining course are assigned.
