PURPOSE:To improve a speed response characteristic (cutting accuracy, high speed cutting performance), by constituting a knife cylinder driving gear by a torque compensator, power amplifier, motor torque detector and a speed compensator or the like. CONSTITUTION:A knife cylinder driving gear is constituted by arranging in parallel plural sets of motor torque control devices, comprising a torque compensator 892 by proportional control, power amplifier 93 using a transistor on the market, motor torque detector 94 ad a brushless motor 70, and providing in addition a set of speed compensator 91 and motor speed detector 8. Speed response performance is improved by using the transistor in the amplifier 93. |
