Abstract

Metallic tubes are cold-drawn by being pulled through a series of swiveling reducing dies each followed by a motor-driven wheel around which the tube forms at least one convolution. The speed of the motors is regulated to insure that the tube is subjected to tensional stresses downstream as well as upstream of each die. The tensional stressing upstream of the dies reduces the resistance which the tube offers to a reduction of its diameter and/or wall thickness during passage through the dies.
