Document Type and Number:

WIPO Patent Application WO/2015/098044

Kind Code:

A1

Abstract:

　A receiving jig for supporting the central part of a plate material to be molded is attached to a rotating shaft in a spin-molding apparatus from a single side surface, the area of the plate material to be deformed being pressed by a processing tool and locally heated by a heater for performing induction heating. The heater includes an electrically conductive pipeline through which a coolant flows, the electrically conductive pipeline having a double-layer arcuate coil part that is aligned with the plate material and extends in the circumferential direction of the rotation shaft, and a pair of leads extending from the coil part radially outward from the rotation shaft. The pair of leads retract at the end on the coil part side so as to be further from the plate material than the coil part.
