Title
(EN) TOOL FOR RF WELDING ARRANGEMENT OF A CENTRAL ELECTRODE AND USE OF A CENTRAL ELECTRODE
Abstract
(EN)
The invention relates to various aspects involved in RFwelding methods.In the process of welding pieces of tubing (12) into films(7,8) with a central electrode (4) it is proposed that thecentral electrode (4) is divided (5,6). This facilitatesthe welding in a single process.In the case of tools (40) with or without a centralelectrode, it is proposed that electrode lamellae(45,46,47,49,50,51) lying next to one another have a freevisual connection between edges (61,62) lying towards theinsert piece (41) . This enables a tight welded joint to beobtained.
