<p>A rotary cutting unit includes a rotary cutter overlying a rotatable anvil. The anvil includes an axle, at least one anvil portion adapted to co-operate with a knife member of a rotary cutter, and a pair of load transmitting portions adapted to abut a pair of abutment members of the rotary cutter. The pair of load transmitting portions are arranged on each side of the anvil portion. A load receiving member is provided between each load transmitting portion and the anvil portion. Each of the load receiving members is connected to the axle via a bearing. Fluid cylinders apply upward forces to the load receiving members, wherein the total upward force exceeds the weight of the anvil.</p> |
