摘要：
A taper rod producing process by which a taper rod having a profile very near to an aimed profile can be produced with high accuracy. According to the process, during working of a wire diameter gradually decreasing portion of a taper rod in which the diameter of a stock gradually decreases in a feeding direction of the stock, the drawing length of the stock from starting to ending of acceleration of variable speed feeding means is made greater than an aimed length of the wire diameter gradually decreasing portion, and during working of a wire diameter gradually increasing portion in which the diameter of the stock gradually increases, the drawing length of the stock from starting to ending of deceleration of the variable speed feeding means is made smaller than an aimed length of the wire diameter gradually increasing portion of the taper rod.
