ABSTRACT OF THE DISCLOSURE A sheet steel poly-V-grooved pulley having a special cross-sectional contour is made optionally by any one of three different cold working manufacturing procedures. Special physical properties of characteristics are developed in the pulley by the manner in which the metal in the V-groove body and single and double walled terminal flanges are cold worked. The cold working involves forming in stages of manu- facturing from a cup-shaped blank to the finished pulley pro- duct a stepped inner body wall surface equivalent to a tapered surface with improved substantially uniform torque transmitting strength in the grooved body from web wall to open end. Also involved in the cold working is an increase in pulley diameter in certain portions of the finished pulley and a decrease in diameter in other portions from the diameter of the side wall of the cup shaped starting blank.
