Patent ID: 6915971

Claim:
A comminuting unit of a comminuting machine for comminuting material, the comminuting unit comprising: a plurality of knife carriers having a longitudinal axis, respectively, wherein the knife carriers are arranged along a comminution path of the comminuting unit and have a leading longitudinal edge, respectively; wherein the knife carriers are aligned with the longitudinal axes transversely to the comminution path and parallel to one another; wherein the knife carriers have an axis-parallel slicing knife, respectively, arranged at the leading longitudinal edge; wherein the slicing knives have a cutting edge, respectively, extending at a predetermined angle and with a predetermined projecting length into the comminution path; wherein axial passage slots are formed between the knife carriers allowing passage of material comminuted by the slicing knives, wherein a rearward longitudinal edge of a preceding one of the knife carriers and the slicing knife of the following one of the knife carriers together define the axial passage slot, respectively, in the comminution path; and wherein the passage slots are in the form of a three-dimensional guide channel, respectively, in order to produce a three-dimensional holding of a strand in the region behind the cutting edge of the slicing knife, the guide channel having longitudinal sides widening in a direction of passage of the material comminuted by the slicing knife, the longitudinal sides defining an opening angle of maximally 20°.
