Abstract
A leveling apparatus having a movable frame which supports a plurality of back-up roller assemblies, each of which is individually positionable to vary the penetration of a portion of the work rolls it contacts such that the penetration of the entry work rolls can be varied independently of the penetration of the exit work roll. Each back-up roller assembly includes an elongate back-up block having a longitudinal slot and a rearwardly-positioned concave surface, an elongate support member positioned within the slot and including a rearwardly-positioned convex surface positioned to matingly engage the concave surface, and a plurality of back-up rollers positioned along the support member. The support member is urged against the back-up block by a resilient connection, and the assembly includes an adjusting screw mechanism mounted on the adjustable frame for pivoting the support member relative to the back-up block. The concave and covex portions of the back-up block and support member, respectively, have centers of curvature which coincide with the rotational axis of the rearmost associated work roll so that pivoting movement of the support member by the jack screw mechanism does not affect the penetration of the rearmost work roll.
