  • Patent number: 4157752
    Abstract: The disclosure is of impression surface conveyor belting and a method for its manufacture. The belting comprises a plurality of substantially parallel textile yarns of a specific character, integrated (in a unitary structure) with a layer of consolidated staple fibers and encapsulated in a matrix of flexible elastomer or resin. Included in the integral structure is an impression wear surface of partially isolated matrix material containing a portion of the consolidated staple fibers (a fiber bundle) which are continuously anchored in a portion of the non-isolated belting matrix. The belting of the invention is useful to manufacture non-laminated, impression surface, conveyor belts which exhibit advantageous properties of wear resistance, stability in running and structural integrity.
