  • the enlarged illustration clearly shows how the heating coil is placed in closely spaced windings in order to form a welding zone 14.
  • the heating coil is formed above the welding zone 14 in such a way that contact areas 16 are formed, via which energy can be supplied. This is preferably done using a pair of pliers, similar to that shown in WO 02/11973 AI, which, however, is guided to the contact areas 16 in a robot-controlled manner in the present case, so that a holding piece provided in accordance with WO 02/11973 AI is identified there with the reference number 16 , is no longer required.
