ABSTRACT:
A method and assembly for making a power transmission belt having driving teeth on opposite surfaces thereof and a tensile member embedded therein. The disclosure also relates to a belt made by the method and apparatus. The method includes providing separate toothed belt portions which will form the two halves of the belt, positioning the first belt portion on a grooved mandrel with the teeth of the first portion disposed within the grooves of the mandrel, applying a tensile member over the outer periphery of the non-toothed surface of the first portion, positioning the other belt portion over the tensile member with its toothed surface facing outwardly of the mandrel; aligning the teeth of the second portion in a predetermined position relative to the teeth of the first portion, retaining the configuration of the teeth of the second portion relative to the teeth of the first portion; and curing the belt portions into a molded integral structure with teeth on opposite surfaces and preferably having a wear-resistant facing covering the opposite toothed surfaces. The disclosed assembly includes means such as a grooved mandrel for maintaining the tooth configuration in the first belt portion and a flexible grooved matrix of special construction for maintaining the tooth configuration in the second belt portion.
