Patent number: 4110396Abstract: A method for the production of curved tubular elastomeric articles such as hose is described which uses a heat recoverable mandrel which when heated above its transition temperature range undergoes a transformation and reverts to a preselected curvilinear shape.

Patent number: 4095480Abstract: 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 supplying means, an annular cavity disposed between the mandrel and pressure means, and means for supplying heat to the mandrel to intitiate its thermal growth during curing of the belting.Type: GrantFiled: September 29, 1975Date of Patent: June 20, 1978Assignee: The Gates Rubber CompanyInventor: Nile L.
