Abstract

624,169. Curving; rolling. SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES DU SUD-EST. Oct. 19, 1945, No. 27604. Convention date, Nov. 21, 1944. [Class 83 (iv)] In machines for curving section-bars by thinning the flanges by inclined rollers, means is provided for varying the inclination of the rolls during the bending operation. For curving a Z bar, Fig. 13, a roller 3 has a generatrix inclined to a supporting roller 2. Rollers 2, 3 and a conical roller 4 are geared together and rotated by an electromotor to thin uniformly the flange and to thin progressively the web. Modifications are described for curving channel and angle sections. Rollers 2, 3, 4 are rotated from an electromotor 9 through gearing 8, Fig. 12. Angular adjustment of the roller 4 is allowed by mounting a shaft 19 and associated gears in a casing adjustable about a bevel drive 23 by a hand-wheel and screw mechanism.
