Welding device and method for welding an outlet element to a packaging material

摘要

The invention is based on a welding device (10a; 10b) for welding an outlet element (12a; 12b), in particular a valve, to a packaging material (14a; 14b), with at least one, in particular self-supporting, anvil (16a; 16b) which comprises at least one receiving area (18a; 18b) for receiving the outlet element (12a; 12b) to be welded, and with at least one welding stamp (20a; 20b), in particular a sonotrode, which is used for welding the outlet element (12a; 12b) to the packaging material (14a; 14b) is set up to interact with the anvil (16a; 16b). It is proposed that the welding device (10a; 10b) comprises at least one magnet unit (22a; 22b) which is set up to hold the anvil (16a ; 16b) at least temporarily in a welding position in which the welding die (20a; 20b) is set up to weld the outlet element (12a; 12b) to the packaging material (14a; 14b).
