Abstract

A device for cutting fibres into pieces, wherein a fibre (10) is divided into pieces (11) by pressing a knife (7) against the fibre (10), said device including a knife roller (2) comprising several substantially axially oriented knives (7) and pressure ribs (8) which are present between the knives (7), and a pressure roller (3), which rollers (2, 3) can be driven in opposite directions at the same peripheral velocity, wherein the knife roller (2) is provided with substantially axially extending mounting sections (19), and in that the pressure ribs (8) are provided on the radially inward side with a recess corresponding to the mounting section (19), which engages round said mounting section (19). <IMAGE>
