Two rolls are supported laterally in bearings in two pairs of side-by-side members with the members being supported by a frame. Adjustment of synchronization and registration is accomplished by adjusting the relative positions of the side-by-side members in or against the rolling direction. The relative positions of the rolls can be adjusted by use of notches engraved in the ends of the rolls; and can be continuously monitored with the aid of a stroboscope light. Magnetic signal devices and other sensors are also suitable for monitoring. Continuous adjustment of roll position is accomplished through low-pitch screws or through hydraulic or electric positioning motors.

Process and apparatus for regulating the synchronization of a pair of

A method of rolling angle structural shapes in which a bar of rectangular ofile is rolled in a first step to form a blank having a rounded convex protuberance on one side and a flat opposite side. In at least one subsequent state, the blank is rolled to transform the protuberance or hump into a triangular protuberance or ridge with flanks lying substantially at a right angle, whereupon the blank is bent, after rounding the edges of the flat surface, to form the angle profile.

Method of rolling angle structural shapes

A method of rolling angular structural shapes with flanges of equal width, specially from steel, in which a substantially round bar or billet is rolled in a first pass to a generally flat intermediate shape having a planar side and a side formed centrally with an upstanding triangular cross-section protuberance. Thereafter, in one or more passes, preferably no more than three passes, the blank is rolled to the angular profile in which the vertex is formed by the protuberance.
