摘要： A skew-toothed belt includes tension members, a tooth portion, and a back portion. The tooth portion and the back portion are located on opposite sides of an array of the tension members. The tooth portion is covered with a tooth cloth, which is arranged such that the weft thread extends substantially perpendicular to the tooth trace direction of each skewed tooth. A method for manufacturing the skew-toothed belt includes the steps of: cutting an elongated tooth cloth material obliquely to the weft direction so as to obtain a tooth cloth sheet; bonding the opposite end portions of the tooth cloth sheet extending along the warp together to form a cylindrical tooth cloth; fitting the cylindrical tooth cloth onto a cylindrical die on which tooth-profiled grooves are formed; sequentially winding the tension members and an unvulcanized rubber compound sheet onto the fitted cylindrical tooth cloth; subjecting the resultant assembly to forming and vulcanization in a pressure chamber; and cutting the resultant cylindrical body into annular toothed belts, each having a predetermined width.
