SYSTEM FOR WELDING FILMS WITH AN INSERT PIECE AND WELDING METHOD

摘要

The system has a central electrode holder (1) and a bag gripper (2) provided in a component, where the system is extended a lengthwise manner. The holder and the gripper comprise a swingable part. A linear transport unit is provided on two system sides. The transport unit i.e. transportation belt, is reversed at a front side (16) of the holder between the two system sides, so that entire transportation is performed by using a single transport unit. A welding station is arranged on one system side and a filling station is arranged on another system side. An independent claim is also included for a method for welding a film with an introduction piece to a bag.
