ABSTRACT:
Method and apparatus for spin-welding thermoplastic articles in which two axially mating sections are driven in rotation relative to each other and then axially abutted in mating relationship. One of the two mating sections is chucked to an inertia member which is brought up to speed by a rotary drive. The rotary drive is uncoupled as the sections are moved into axial abuttment and the braking of the inertia member by the axial abuttment of the sections is transformed into frictional heat which welds the sections to each other. Apparatus for spin welding sections on a production line basis is disclosed.
