<p>METHOD AND APPARATUS FOR MAKING POWER TRANSMISSION BELTING The method involves assembling an uncured belt body having a stable length tensile section adjacent an inwardly disposed mandrel made of a metal having a high coefficient of thermal expansion, heating the mandrel whereby its thermal properties are utilized to maintain the tensile member in tension, also pressurizing the belt body in a direction toward the mandrel thus sandwiching it, and while maintaining the tensile member in tension, curing the belt body from which one or more endless power transmission belts may be formed. The apparatus utilizes the mandrel in a substantially ring or cylindrical shape about which is disposed inwardly pressure supply 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.</p> |
