  • Toothed belt
    Patent number: 5529545
    Abstract: A toothed belt (1) having a woven fabric (5) adhered to its meshing face, wherein the woven fabric (5) has longitudinal yarns (9) extending in the longitudinal direction of the toothed belt (1) and formed of covered yarns (15), each of which is prepared by turning a high tensile strength and heat resistance fiber yarn (17) on a core (16) made of an elastic yarn and by further turning a synthetic fiber yarn (18) on the high tensile strength and heat resistant fiber yarn. The high tensile strength and heat resistance fiber yarn (17) is restrained by the covering synthetic fiber yarn (18) so that it does not protrude in the form of large loops, thereby reducing the bulkiness of the woven fabric (5). As a result, the toothed belt is excellent in wear resistance and durability.
