Method for joining reinforced glass fiber polytetrafluoroethylene films by ultrasound, involves arranging reinforced glass fiber polytetrafluoroethylene films in overlapped manner

摘要

The method involves arranging reinforced glass fiber polytetrafluoroethylene films in overlapped manner, and arranging perfluoroalkoxy copolymer film between two slides in the welding area. The ultrasound sonotrode is supplied with a defined pressure, a defined ultrasound amplitude and a defined traverse speed over the two overlapped reinforced glass fiber polytetrafluoroethylene films. The sonotrode is supplied continuously by the welded and overlapped reinforced glass fiber polytetrafluoroethylene films. An independent claim is included for a sonotrode for joining reinforced glass fiber polytetrafluoroethylene films by ultrasound.
