<p>Apparatus for cutting and/or shearing elongate lengths of fibre into shorter lengths has two adjacent rollers (7) and (8), and means for supplying an elongate length of fibres to the rollers. The rollers (7) and (8) are disposed in a housing (1) and define a nip therebetween. One roller (7) is a pressure roller and the other a blade housing roller. Blades are advanced through slots in the housing of the blade housing roller (8) to cut fibre into shorter lengths and projected towards a delivery slot. Air jets through apertures (20 and 21) in the wall of housing (1) guide shorter fibres out of the housing.</p> |
