Abstract: A process of producing a rubber article which is economical and environmentally beneficial in that it provides for the recycling of ground cured rubber into uncured rubber compositions which need only be molded or shaped into their final form.

Abstract: A belt of integral unitary construction for transmitting power at low tensions and the method of making the belt. The belt includes a continuous body having top and bottom surfaces which are equally spaced apart across the width and throughout the continuous length thereof. The body comprises a neutral axis section extending throughout the length of the belt with a tension section on one side thereof extending toward the top surface of the belt and a compression section on the other side thereof. The tension section extends transversely across the entire width of the belt and at least one groove is provided in the compression section extending from the bottom surface through the compression and neutral axis sections into a portion of the tension section to form a plurality of power transmitting ribs extending longitudinally of the belt to provide a tension section, compression section, and neutral axis in each individual rib.
