Abstract
A belt construction and method of making the same are provided, the belt construction comprising a tensile member intermediate the opposed sides of the belt construction, 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 and is substantially free of fibers therein, the material of the backing member having a surface that joins with a surface of each tooth whereby the joining surfaces define an interface line therebetween, the interface line for each tooth extending from the tensile member at a point inboard of one of the opposed sides of the respective tooth into the medial portion of the respective tooth and then back to the tensile member at a point inboard of the other of the opposed sides of the respective tooth whereby part of the material of the backing member defines part of the medial portion of each tooth, the surface of the backing member also joining with a surface of the first material in each land area whereby the joining surfaces in each land area define an interface line therebetween, the interface line in each land area having a portion thereof disposed spaced from the tensile member on the side thereof opposite to the side thereof that faces toward the teeth.
