Abstract

A sizing press has a pair of opposed rotatably supported pressing tools for reducing the width of a flat metal slab. Piston cylinder assemblies rotatably oscillate the pressing tools relative to each other. Each pressing tool has first and second slab-contacting surfaces which extend in different planes. The invented method of this invention includes the steps of moving the pressing tools toward each other against the sides of a metal workpiece and reducing the width of an initial workpiece length. Thereafter, rotating the pressing tools to further reduce the width of only a portion of the initial workpiece length and to reduce the width of an adjacent workpiece length.
