ABSTRACT:
A tool with opposing lower and upper dies and opposing lower and upper plates disposed in spaced-apart relation to the lower die and the upper die, respectively. The dies and plates define opposing profile surfaces that conform to an exterior cross-sectional profile of a plastic member for being received and held therebetween. Movable mount means connects the lower plate to the lower die and the upper plate to the upper die independently for lateral movement of the plates relative to the dies between a first distally spaced position to a second closely spaced position. During the welding process, the plates move laterally between the first position and the second position to seal the weld material that melts from the distal ends of the members from flowing to the exterior of the joint being formed between the plastic members. The plates seal the exterior profile and force the weld material to flow inwardly of the joint. An apparatus using two of the tools is disclosed together with a method of welding a pair of plastic members while reducing the excess plastic on the exterior of the weld joint.
