Abstract

PURPOSE: To obtain a ring which is of uniform curvature over the entire circumference, has high roundness and has no rubbing flaws by forming a guide member which winds the steel strip formed to required curvature into a freely rotatable ring of which the center is determined by 3 or more vertical rolls.
CONSTITUTION: A dummy sheet steel 21 is inserted into a bending machine 3, and the trailing end thereof and the leading end of a steel strip coil 1 are joined. Next, the bending machine 3 is driven to unroll and form the coil 1 and advance the curved steel strip 4. The part of unstable curvature near the leading end thereof is cut off. Thence, the machine 3 is operated continuously and while the coil 1 is formed to the curved steel strip 4 of predetermined curvature, it is wound on the outside circumference of a guide ring 10. The ring 10 has a radius of curvature approximately equal to the radius of the forming curvature of the steel strip 4. The center of its rotation is determined by three vertical rolls 11 on the circumference, and the ring is supported by horizontal rollers 12. Where the steel strip 4 of a predetermined ring circumferential length is obtained, the winding is stopped and the steel strip 4 is cut, after which it is removed from the bending device by a hoisting device and the cut ends are butt-welded.
