Abstract

943,615. Making tubing; coiling; bending. BABCOCK & WILCOX Ltd. Oct. 29, 1962 [Oct. 30, 1961], No. 40716/62. Headings B3A and B3E. A method of forming a curved tube length of asymmetrical lenticular crosssection comprises giving a tube length of elliptical cross-section the desired curvature by passage past rollers so peripherally grooved as to impart to the tube the desired cross-section. Tubing of elliptical cross-section is bent or coiled by passage between a bending roller and a pair of bearing rollers, the bending roller being so grooved as to produce the profile 2 and the bearing rollers the profile 3. Other asymmetric lenticular profiles may be formed. Return bends may be formed in a similar manner.
