Abstract

A rolling stand for hot or cold rolling of bar steel or wire rod stock, including a pair of chocks for rotatably supporting a pair of rolls and means for effecting movement of one of the chocks toward and away from the other chock to effect the relative positions of the rolls. Apparatus is provided for applying a prestressing force to one chock in a direction tending to urge the chocks apart, the apparatus including at least one spring whose force remains substantially constant independent of the position of the chock.
