Abstract
A knife carrier for a chopper drum is formed with a plurality of knife carrier segments, each designed as a circular-ring disk section of a circular-ring disk that can be accommodated on an outer diameter of a circular-cylindrical drum body of the chopper drum. The knife carrier segments each have an outer-peripheral surface having a predetermined number of knife receptacles. The knife carrier segments each have a circumferential length such that all the knife carrier segments form the circular-ring disk when placed next to one another along the circumferential length thereof. Each knife carrier segment has fixing means for the defined positioning of the knife carrier segments with respect to the drum body and for the detachable attachment of the knife carrier segment on the outer diameter of the drum body.
