Abstract (en)
A drive arrangement for a cutter blade, wherein operational cutting movement of the blade (11) is arranged to be derived from a servo-type motor (9) whose output is so controllable as to provide a drive output voltage/time relationship which produces a rapid initial acceleration from rest to a value which produces such angular velocity of the output shaft (10) of the motor as to establish a pretermined torque (angular momentum) in the blade (11) sufficient to cause the blade to effect a material cutting stroke and then on completion of a blade cutting stoke a rapid deceleration to bring the output shaft and thus the blade to a rest position.
