Abstract
A toothed belt wherein the toothed portion is covered with a cover cloth consisting of a weft and a warp. The weft consists of weft yarns defined by an elastic core yarn and by at least one composite yarn wound about the elastic yarn; and each composite yarn comprises a high thermal and mechanical resistance yarn and at least one covering yarn wound about the high thermal and mechanical resistance yarn. To improve adhesion of the cloth to the elastomeric material of the belt body and teeth, to improve abrasion resistance and to extend the average working life of the belt, according to the present invention, the cloth is treated with an adhesive composition comprising resorcinol, formaldehyde, a highly saturated and carboxyl groups containing nitrile and conjugated diene copolymer latex, and epoxy resins.
