ABSTRACT:
A knife holder unit combined with a rotary knife pair includes a frame composed of an upper frame part and a lower frame part; and an upper and a lower knife holder assembly supported in the upper and the lower frame part, respectively. Each knife holder assembly includes a bearing shaft composed of a first bearing shaft part having a longitudinal axis and an adjoining second bearing shaft part. The first bearing shaft part is received in a recess of a respective frame part for turning motions therein about the longitudinal axis. A first securing arrangement immobilizes the first bearing shaft part relative to the respective frame part. A rotary bearing surrounds the second bearing shaft part and has a rotary axis which is offset relative to the longitudinal axis to define an eccentricity therewith. A rotary knife is mounted on the rotary bearing. The rotary knife of the first knife holder assembly and the rotary knife of the second knife holder assembly cooperate with one another and together define a cutting plane which passes through the rotary bearing of the upper and lower knife holder assemblies. A second securing arrangement affixes the rotary knife to the rotary bearing.
