  • Method of controlling a rotary cutter
    Patent number: 4724732
    Abstract: A method of controlling a rotary cutter in which material of long size such as steel plate or corrugated cardboard moving between a pair of rotating shears each having a shearing edge on its peripheral surface is cut in a predetermined cut length by controlling a motor for driving the shears, wherein the provision of steps of calculating an optimum shear position with minimum energy on the basis of moving quantity of the material, calculating minimum optimum shear velocity and optimum motor current on the basis of the moving quantity of the material and moving velocity of the material, and rotating the shears so that the calculated condition is realized. The shear position and the shear velocity of the rotary cutter and the drive motor current are selected to the optimum condition with minimum energy and operation can be made under the condition of minimum energy.
