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

A welding device (10a;

• 10b) for welding an outlet element (12a;
• 12b) to a packaging material (14a;
• 14b), the welding device (10a;
• 10b) comprising:
• at least one anvil (16a;
• 16b) including at least one receiving region (18a;
• 18b) for receiving the outlet element (12a;
• 12b) that is to be welded;
• a holding element (20a;
• 20b) on which the anvil (16a;
• 16b) is arranged;
• at least one welding die (22a;
• 22b), which is configured to interact with the anvil (16a;
• 16b) to weld the outlet element (12a;
• 12b) to the packaging material (14a;
• 14b);
• and
• at least one support unit (24a;
• 24b) for supporting the anvil (16a;
• 16b), the support unit (24a;
• 24b) including at least one movably supported support element (26a;
• 26b), which is configured to exert a holding force onto the anvil (16a;
• 16b) when the welding die (22a;
• 22b) is in a welding operation state,
• wherein the movably supported support element (26a;
• 26b) has a movement axis (72a;
• 72b) along which the movably supported support element (26a;
• 26b) is movable relative to the anvil (16a;
• 16b).
