Abstract

1258. Delecroix, C. A. M. J. Jan. 21, 1908, [Convention date.] Angular bending. -Tubes are made from sheet metal by rolling the blank when hot or cold into the shape shown in Fig. 4, the portions 1, 1 being of the curvature of the tube and in the right direction while the portion 3 is reversed, so that by another rolling the portion 3 is turned outwards to the right curvature as shown in Fig. 6. The blank is then submitted to a further rolling which curves the flattened portions 2, 2, and finishes the tube. For lined tubes, a blank as shown in Fig. 9 may be used.
