Abstract
PURPOSE: To prevent cutting length error from occurring dependent on the thickness of the materil to be cut through obtaining the optimum circumferential speed of a cutting blade and starting timing signal and through making computation on the basis of the thickness of said material.
CONSTITUTION: Cutting at the cutting point of the material to be cut 4 is made by the cutting blade 2 provided on a cutter drum 1. In this case, the circumferential speed of said cutting blade 2, i.e. of said cutting drum 1, is determined in consideration of the distance l1 between the center of said cutting drum 1 and a material detector 5, the cutting length l2 and feed speed VB of said material 4, and the circumferential distance lSO between the starting position of said cutting blade 2 and said cutting point. However, the contacting position of said material 4 with said cutting blade 2 deviates forward over distance ΔlB and in angle ΔlS due to the thickness h of said material 4. For eliminating cutting length error, the timing of said cutting blade 2 is determined by making computation in consideration of values of said distance ΔlB and abgle ΔlS.
