Abstract

PURPOSE: To manufacture a fan-shaped strip in a high yield through a single rolling pass, by rolling a straight strip with a draft percentage gradually increased from one edge to another edge of the strip.
CONSTITUTION: A straight strip 1 with breadth W0, total length L0 and thickness T0 is rolled with a draft percentage increased from its one edge to another edge. Hereupon, the strip 1 is rolled by two rolling rolls 2, 3 whose axis lines make an angle α. The left and right axial distances of two rolls 2, 3 are adjusted by operating an adjuster such as bolt, wedge,etc., in order to adjust the angle α made by roll axes of the rolls 2, 3 and to adjust the left and right thicknesses t0, t1 of the rolled strip. A fan-shaped strip 1' obtained by this rolling pass can be formed from a straight strip 1 as the blank material so that the yield is improved and the material is saved, which reduces the material cost; and besides, the fan-shaped strip 1' can be obtained by a single rolling pass so that the working man-hour is reduced.
