Abstract

PURPOSE:To eliminate the useless loss of material, and to shorten the working process and working time, by employing rolling rolls provided with a wedge form roll gap for rolling a straight strip so as to warp it. CONSTITUTION:A strip 2 is rolled by work rolls 1, 1' whose roll gap is narrowed in the direction of breadth of strip 2; hereupon, the draft percentage is gradually increased from one edge to another edge. By this rolling pass with a draft percentage varied in the direction of breadth, the strip 2 is formed to a fan shape. This fan shaped strip 2 is bent in the direction of thickness by a bender comprising the work rolls 1, 1' and a block 3; hereby, a conical ring is obtained.
