Abstract
A belt (1), and a method of forming a belt (1), with at least one row of teeth (5) formed on at least one surface of the betling (1). To improve the tooth formation of the belting (1), and the abrasion of the belting (1), the outer surface of the teeth (4) are formed with the disclosed bi-directional stretch woven fabric (7). The warp (10) and weft (11) yarns are formed of a core yarn (12) about which is helically wrapped at least one yarn (13 or 14), forming a scaffold construction. The bi-directional stretch characteristics of the fabric (7) permit greater deformation of the fabric (7) while forming the belt teeth (5).
Claims16
An improved drive belt (1), the belt (1) being comprised of at least one row of transversely extending teeth (5), and a fabric layer (7) reinforcing the outer surface of the teeth (4), the belt (1) being character by:
- the fabric (7) being a woven bi-directional stretch fabric (7) comprising warp (10) and weft (11) yarns;
- each warp (10) and weft (11) yarn comprising a first core yarn (12) with at least one second yarn (13) wound about the core yarn (12).
A method of forming an improved drive belt (1) for industrial application comprising providing a resilient elastomer belt (1) body, forming at least one row of transversely extending teeth (5), and reinforcing the teeth (5) with an abrasion fabric (7), the method characterized by:
- forming the abrasion fabric (7) from a woven bi-directional stretch fabric (7) comprising weft (11) and warp (10) yarns, each warp (10) and weft (11) yarn comprising a first core yarn (12) with at least one second yarn (13) wound about the core yarn (12).
