In a method of trimming a width of an elongate sheet stock by a side trimmer, respective minimum widths of both side portions, i.e. a work side portion and a drive side portion, of the stock are measured in advance, and then respective trimming allowance values of the two side portions are determined on the basis of the thus measured minimum widths thereof, respectively. According to this method, the elongate stock can be kept free from insufficiency of the trimming allowance during the trimming operation. Thus the present method makes it possible to determine an optimum set value for the side trimmer to trim the elongate stock in consideration of the actual width of the stock and a desired final width of a finished stock or product. |
