Abstract

133,142. Edwards, E. A., and Wells, A. Oct. 1, 1918. Drawing-dies. - In the manufacture of metal tubes by drawing strip metal, previously heated to welding temperature, through a bell, so that the strip is brought to tubular form and the butting edges welded together, the bell has two tapered portions 1, 3 connected by a cylindrical portion 2. The portion 1 brings the strip to the form of an openjointed tube, the portion 3 closing the joint and welding the edges.
