Abstract

A method for making a ball for sports comprises providing a round rubber tube, forming a reinforcing layer of a yarn wound about the tube, forming a rubber cover layer formed on the reinforcing layer, and vulcanizing the rubber cover layer to provide a carcass. In the method, the reinforcing layer is formed by winding, in combination, a covered yarn made of a urethane elastomer core thread wound thereabout with a synthetic resin filament or in combination with the synthetic resin filament and a yarn made of a member selected from the group consisting of cotton, polyesters and polyamides. The carcass may be attached with a skin layer made of a natural or artificial leather. Alternatively, the round rubber tube having the reinforcing layer may be attached with a skin layer.
