Abstract

1434207 Profiling metal rod TETRACERO SA 7 Sept 1973 42305/73 Heading B3M Apparatus for cold rolling ribs on steel rod includes a cylindrical housing 6 which supports skewed rolls 10 and rotates about a fixed tube 7 through which the rod 5 passes. The rolls, of which there may be two or four, define a pass, Fig. 5, such that helical ribs 14 are formed on the rod. Slots in the bottoms of the roll grooves also form transverse ribs on the rod. The rolls are adjustable towards and away from the pass line. Traction apparatus pulls the rod through the rolling apparatus and also through an initial straightening and pickling assembly.
