Abstract

Abstract Apparatus is disclosed for restraining and controlling the edges of a mass of material, especially a package of particulate metal, as the material enters the bite of a rolling mill. The apparatus contains two wear block members adapted to fit into the bite region of the rolling mill and to guide and restrain the edges of the material being rolled. The wear members are supported at corresponding ends of substantially parallel frame members, with one wear block on each frame. The frame members are joined together by one or more tie rods and caused to pivot slightly about the tie rods, which act as fulcrums, by means of hydraulic cylinder and piston so as to maintain substantially uniform force through the wear blocks on the material being rolled.
