ABSTRACT:
The apparatus utilizes a mandrel in a substantially ring or cylindrical shape about which is disposed inwardly pressure supplying means, an annular cavity disposed between the mandrel and pressure means, and means for supplying heat to the mandrel to initiate its thermal growth during curing of the belting. The metal of the mandrel has a high coefficient of thermal expansion which during use applies radial outward pressure against the belt body being cured.
