The cutter wheel 55 is rotatably mounted in a bracket 49 pivotably mounted relative to a stationary bracket 61 on which the anvil wheel is rotatably mounted; the wheels are rotated by a motor 65 via gears 67 and respective spindles 53, 59. Resilient feed rollers 57, 63 are mounted on the spindles. The anvil wheel is urged towards the cutter wheel by a spring 73, Fig. 4, the gap between the cutting edge and groove being determined by an adjusting screw 75.
