ABSTRACT:
A flat belting includes a plurality of individual layers of fabric that extend throughout the length and width of the belting. The layers are joined together by reinforcing elements which extend substantially in the direction of the thickness of the belting. The individual layers and reinforcing elements are encapsulated in a matrix of polymeric elastomeric resin, for example, polyvinylchloride. The individual layers are saturated with a liquid elastomer-forming polymeric resin prior to their being joined together. The reinforcing elements may be inserted, for example, by tufting, sewing, or stitch-bonding. One or more of the individual fabric layers may be a woven or other cloth having a plurality of substantially parallel yarns which extend in the lengthwise direction of the belting. One or more of the individual fabric layers may be a non-woven fabric.
