Abstract
A horizontal or vertical roll stand for a rod or bar rolling mill comprising a pair of work rolls having a plurality of grooves spaced axially along the surfaces thereof, each work roll being journalled between bearings contained in bearing chocks, with the bearings being adapted to accommodate axial adjustment of the work rolls in relation to the bearing chocks. The bearing chocks are supported in a housing with the work rolls in parallel relationship and with the grooves defining a plurality of roll passes. An axial roll adjustment means is associated with each work roll. Both of the axial adjustment means are driven by a common axial adjustment drive. A clutch is connected between one axial adjustment means and the axial adjustment drive. When engaged, the clutch permits the axial adjustment drive to operate through both axial adjustment means, thus axially adjusting both work rolls simultaneously. When the clutch is disengaged, the axial adjustment drive operates through only one axial adjustment means, with the result that one work roll is adjusted axially in relation to the other work roll. The work rolls are additionally acted upon by roll parting adjustment means driven by …
