Abstract
469,004. Angular bending; coiling helices. MANNESMANNROHRENWERKE. Jan. 9, 1937, No. 720. Convention date, Jan. 17, 1936. [Class 83 (iv)] Tubes for bends, coils, &c. are bent to the required curvature and the flattened tube is then re-shaped in cross-section by pressing in dies to an oval shape with the major axis e in the plane of the bend. The difference in lengths of the major and minor axes may be from 5 to 25 per cent of the length of the minor axis d.
