ABSTRACT:
In a chopper, at least one cutter rotates about an axis moving over a retaining wall of a chopper housing and past an opposing knife edge located at the inlet opening into the chopper. The opposing knife edge is adjustably supported on a support relative to the plane or circle of revolution of the cutter. An adjustment device actuatable at a location exterior of the chopper housing effects the adjustment of the opposing knife edge when a locking device is released. The locking device includes a clamping device for pressing the opposite ends of the opposing cutting edge against the support. A force accumulator provides an elastic force for maintaining the clamping action. The locking device also includes a releasing device acting against the force accumulator for releasing the clamping action.
