Abstract

PURPOSE: To greatly improve the yield in producing steel bands through reduction of trimming margin to half by providing bridle rollers before and after a trimming region to sufficiently tighten a steel band and to shear off the steel band only along the triming edge side thereof.
CONSTITUTION: A shearing machine 2 is disposed along the trimming edge 1b of a steel band. The cutter 21 of the shearing machine is engaged with the trimming edge 1b. Bridle rollers are provided before and after the trimming region so as to apply a particularly high tension to the steel band 1 passing through the shearing section. The position of the cutter relative to the edge 1b is determined on the basis of the sum of a width correcting value (e) corresponding to the size to be trimmed off and an additional error (f) which needs correction to trim the steel band into the steel band of the predetermined width, thus reducing the trimming margin to a half and improving the yield of the product.
