<p>Joining of thermoplastic parts (2, 4) of indeterminate thickness to each other is effected by application of heat to selected surface areas thereof (42, 44) by intense focussed infrared heat lines produced by parabolic-elliptical-reflection heat sources (22, 24) displaced by a reciprocating linear actuator (26), removable by a robotic controller (36) after completion of heating to enable intermediate pushing together of the parts by further actuators (32, 34) for bonding.</p> |
