Abstract

PURPOSE:To perform a tension-out type, stable and high-precision trimming work by utilizing a strip-steel meandering-correction device, a strip-steel side- guide device and a position controller, in the strip-steel trimmer of an acid cleaning line. CONSTITUTION:Couples of light emitters a, b and light-intensity sensors 20, 20, positoined so as to face each other near a steering roller 121, detect any offset of strip steel in the left-right direction through an area shielded by the strip-steel edge, the the offset thus obtained is processed by an arithmetic unit 30, and input to a steering-roller tilting mechanism 40, the rollers are tilted in the left or the right by a required amount of angle, and the strip steel is returned to the central position. Vertical rollers r, rotatably positioned at the guiding parts 141, 141 of a strip steel side-guide device 14, and set widths among which are adjusted corresponding to the width of the passing strip, guide the band, in contact with the strip steel edge. With this constitution, a load exerted on the trimmer is markedly reduced, tension-cut type high precision and stable trimming work is performed without using a looping pit, thereby installation cost is reduced, and energy saving effect is also resulted.
