Abstract

61. Weiss, F. Jan. 1. Flanging.-The inwardly-directed stiffening flanges of concave bodies or shells, such as the sides of cases, are strengthened by pressing or rolling the bodies in such a manner that the flange is thickened. A flat blank is first stamped into the form shown in Fig. 1, and the flange b is bent upwards and the wall pressed thinner at c, Fig. 3. The material pressed aside thickens the flange b and forms a ridge d, which is afterwards removed. In a modified process, a flat blank is acted on by a roller f, Fig. 5, the periphery of which is provided with an elevated portion h to form a thickened rim I. The blank is then clamped up into its final shape.
