ABSTRACT:
An edge trimmer system in accordance with the present invention includes a conveyor system, a cutting assembly, and a pair of starter punches. The cutting assembly includes a pair of side trimmers each with a cutting device which trims one of the elongated edges of a raw strip of steel to produce a parent steel strip and two scrap steel strips. The method includes the steps of stopping the cutting devices from cutting the raw steel strip when only one of the cutting devices is engaged in trimming the raw steel strip; automatically punching first and second starter punch openings through the raw steel strip, each of the first and second starter punch openings being adjacent to one of the elongated edges of the raw steel strip and directly opposite each other, the first starter punch opening extending in a first distance from one of the elongated edges and the second starter punch opening extending in a second distance from the other elongated edge of the raw steel strip; and advancing the first and second starter punch openings in the raw steel strip to the cutting devices to allow the raw steel strip to realign and to re-establish trimming on both sides of raw steel strip in the cutting assembly.
