ABSTRACT:
Continuous extrusion apparatus includes a rotatable wheel, the rotatable wheel including a circumferential groove. Continuous extrusion apparatus includes a shoe including an arcuate tooling bounding a radially outer portion of the groove provided with an exit aperture in a die body and an abutment displaced in the direction of rotation from the exit aperture. The shoe includes a heater body assembly including an electrical induction heating coil assembly arranged to be energisable to co-act with a magnetisable element to effect electrical induction heating thereof; and an element is provided to thermally induce movement of co-acting members for one of expanding and contracting to adjust clearances between the rotatable wheel and the abutment and the shoe within requisite limits.
