Abstract: Feeding means for successively advancing elongated workpieces step-by-step, through the central workpiece receiving passage in a multiturn induction heating coil with a workpiece supporting slide track extending therethrough, has an elongated workpiece pusher member extending longitudinally through the passage and provided with workpiece engaging driving lugs spaced therealong. Combined transport and elevating means reciprocate the pusher member axially of the passage between a retracted and an extended position to advance the workpiece into and subsequently out of the heating coil passage and shift the pusher member between two different elevational positions in which its driving lugs are respectively located in the path of travel of the workpiece along the slide track during the advance stroke of the pusher member and out of the path of travel during the return stroke of the pusher member.
