Abstract
1,249,215. Transverse rolling. TOYOTA CHUO KENKYUSHO K.K. 28 Feb., 1969 [1 March, 1968], No. 10745/69. Heading B3M. Cylindrical stock 5 is profiled by transverse hot-rolling it between a pair of identical rolls 1, 1<SP>1</SP>, each roll having helical projections 3 and 4 formed on its surface. The projections 3 serve to feed the stock axially and have a lead angle equal to the degree of skew of the rolls relative to the stock axis. If successive profiled workpieces are to be severed from the stock, the projections are provided with cutting edges 321, Fig. 5, at their trailing ends. The projections 4 are wedge-shaped and may have a portion 43 of uniform cross-section at their ends for finishing a workpiece. The bodies of the rolls may be hyperboloids, or frusto-conical shape rather than cylinders. The projections 4 may be provided with serrations for gripping the stock, and several overlapping projections may be used for rolling more complicated profiles.
