PROBLEM TO BE SOLVED: To cut a sheet-like continuous material always at right angles or at a fixed angle by using servo motors having a function of varying the magnification of a command pulse to an input pulse for the drive of an advancing sheet-like continuous. material and the drive of an advancing cutter, respectively, and electrically synchronizing the motors with each other. SOLUTION: When the advancing speeds of a sheet-like continuous material and a cutter are taken to be V, v, and the angle made among the advancing direction of the sheet-like continuous material, the right-angled direction and the advancing direction of the cutter is taken to beθ, at the time of cutting the sheet-like continuous material 1 at right angles, the relation is expressed by V=vsinθ. The diameter of a driving feed roller 3 for the sheet-like continuous material is equal to the diameter of a cutter driving pulley 6, the command pulse magnification of the servo motors 2, 4 for driving the sheet-like continuous material and the cutter is set to 1, 1/sinθ, and the respective servo motors 2, 4 are wired in parallel to the input pulse. By this arrangement, even if the advancing speed of the sheet-like material is changed or varied, the sheet-like continuous material 1 can be cut always at right angles.
