Abstract
The invention relates to a knife assembly for slicing woodwool, comprising a knife with a chip surface (1), a clearance surface (2) and a cutting edge (3), defined by the intersection between both surfaces. The knife assembly is characterized by guiding ribs (4) extending perpendicularly to the cutting edge (3) and joining the chip surface (1) with an end (5) that substantially coincides with the cutting edge (3) and with the guiding surface joining said end and rising there towards. The guiding ribs (4) can be formed integrally with the knife.

A knife assembly for slicing woodwool, comprising:
- a knife with a chip surface, a clearance surface and a cutting edge defined by the intersection between said chip and cutting surfaces;
- and
- a plurality of guiding ribs extending perpendicularly to the cutting edge, each said rib joining the chip surface with an end that substantially coincides with the cutting edge and having a guiding surface joining said end and rising there towards to form a non-cutting region adjacent said cutting edge.
