Abstract

PURPOSE:To bite a strip between rolling rolls at no off-center and to prevent it from meandering and curving by copy-joining rollers set on arms to the tip part and the side parts of the strip to perform the centering of the strip. CONSTITUTION:When the tip 6a of the strip 6 is carried, each roller 11 tracks the widened part 6aA of the tip 6a through copy control under a fixed pressure. When each roller 11 reaches a steady width part 6aB and immediately before the tip 6a bites into a rolling roll 2, the hydraulic pressure of each hydraulic cylinder 12 is controlled by a servo circuit part based on a positional signal from a positional sensor 15 to perform the centering of the strip 6. After this centering is completed, a short stroke control is followed. Consequently, the strip can be prevented from meandering and curving.
