Abstract
A controller for cutting sheet material so that inferior or incomplete sheet material is eliminated is characterized by the provision of means for detecting a length of sheet passing through a rotary cutter which continuously cuts the sheet material, means for calculating a length of sheet moving until the sheet is cut after a shear is started, and means for controlling the start timing of the shear so that a cut portion of sheet cut first by the shear coincides with a cut portion of sheet cut by the rotary cutter.
