METHOD AND DEVICE FOR BUTT JOINTING TUBES MADE FROM PLASTIC MATERIALS

摘要

According to the invention, two tubes (11), (12) made from plastic material the ends (111), (121) of which are closed, may be butt-jointed by compression and welding or gluing of the tube wall, axial alignment and abutment of the two closed ends (111), (121) of the tubes (1 1),(12), remote non-contact heating of the two closed ends (1 11), (121) butting the tubes (11), (12) and axially bringing the two ends (111), (121) of the tubes (11), (12) together such as to swage and butt weld the ends (111), (121) of the tubes (11), (12), whilst maintaining said ends (111), (121) constantly abutted.
