ABSTRACT:
A belt construction and method of making the same are provided, the belt construction having opposed sides and comprising a plurality of teeth defining one of the opposed sides of the belt construction and being mainly formed of a first polymeric material that has reinforcing fibers therein, each tooth having opposed sides that are disposed in spaced relation to adjacent sides of adjacent teeth, the belt construction having a land area between adjacent teeth, and a backing member defining the other of the opposed sides of the belt construction, the backing member being mainly formed from a second polymeric material that is initially separate from the material of the teeth. The method comprises the steps of providing a grooved drum, disposing the first polymeric material in a non-cured form thereof about the drum, then subjecting the drum to heat and pressure to cause the first material to be forced toward the drum and exude into the grooves to at least partially form the teeth, then substantially immediately cooling the first material and the drum to stop the curing of the first material so that the first material is generally in a non-cured condition, then disposing the second material in a non-cured form thereof about the first material on the drum, and then again subjecting the drum to heat and pressure to cause the first and second material to be forced toward the drum to complete any remaining unfinished portion of the teeth and be cured together to form the belt construction.
