The invention relates to various aspects of RF welding methods.When welding pieces of tube (12) in films (7, 8) with a central electrode (4), it is proposed that the central electrode (4) is divided (5, 6). This makes it possible for welding in to be performed in a single operation. For tools (40) with or without a central electrode it is proposed that electrode lamellae (45, 46, 47, 49, 50, 51) lying next to one another should allow a free view between edges (61, 62) lying towards the insert piece (41). This allows a tight welded joint. |
