Abstract

Rolling mill apparatus including a pair of roll assemblies (10,12) each constituted by a rotatably mounted support roll (14,16) and a plurality of work rolls (18,20) spaced around said support roll. So that the mill will be capable of relatively high reductions and will require only a relatively low power input, the work rolls are backed by respective cradle elements (22,24) and means are provided whereby each work roll (18,20) and its respective cradle elements (22,24) are initially positioned in readiness for a bite by the work roll into a workpiece being fed between the roll assemblies, said work roll and cradle element roll together through an arc of movement in which a bite into the workpiece is taken, and said work roll and cradle element are then caused to precess around the support roll (14,16) to their initial positions relative to said support rolls.
