Abstract
The cutting mechanism comprises a driving shaft and a driven shaft. A motor is connected to the driving shaft and rotates the driving shaft in a first direction. A gearing arrangement interconnects the driving and the driven shafts so that rotation of the driving shaft causes concomitant rotation of the driven shaft in a direction opposite to the first direction. Coacting cutting means are provided on the driving and the driven shafts for cutting material received therebetween. A motor is connected to the driven shaft and rotates the driven shaft in a direction opposite to the normal direction of rotation of the driven shaft to eliminate backlash between the coacting gears. Thus, the clearance between the cutting edges of the rotary cutting means is always constant and uniform.
