Abstract

1,204,814. Rolling. STAHLWERKE BRUNINGHAUS G.m.b.H. 25 Oct., 1968 [4 Nov., 1967], No. 50694/68. Heading B3M. A tapered metal bar 1 is formed by rotating a cylindrical bar about its axis and traversing a group of rolls 2 along the bar while progressively moving the rolls radially inwards. The rolls are radially adjustable by means of a transverse arm 6 whose free end follows a fixed template 5. The arm rotates a housing portion 11 which by means of cam surfaces 14, pivots the rolls radially. The rolls are skewed relative to the bar, and are conveniently mounted in the carriage of a lathe, the bar being rotated by chucks of the lathe.
