Abstract

1393926 Rolling mills POMINI FARREL SpA 8 Sept 1972 [10 Sept 1971] 41878/72 Heading B3M A continuous roughing train for rolling bars includes alternate vertical rolls stands (Fig. 2) and similar horizontal roll stands (Fig. 3, not shown), driven from a common shaft 15, each stand having a pair of cantilevered rolls 31 carried in housing halves 21 and 22. The rolls are driven via bevel and spur gearing from the shaft 15, and are adjustable towards and away from each other by asymmetrically arranged rods 32 (Fig. 5, in plan). Each rod is oppositely threaded at its two ends such that rotation of the rod adjusts the roll gap. An hydraulic or mechanical overload assembly 37 is associated with each rod for protecting it against excess stresses. One roll 31 of each pair (Fig. 2) is carried in a support 42 which is adjustable at 43 to move the roll axially relative to the other roll.
