<p>An apparatus for cutting fibrous reinforcement material (10) in relationship with an ejector nozzle (19). The apparatus comprises at least two feeding rollers (11, 12) and a rotary cutter (16) which is provided with a substantially cylindric mantle surface with attachments for a number of knife means (22). These cooperate with a support roller (17) with an elastic surface layer (17a) for forming a thread nip. The mantle surface of the cutter (16) is provided with slot-shaped recesses (24) for the fibre thread (10), which recesses extend peripherally along the mantle surface between the knife means (22). The recesses enable the thread to be fed forward by means of the feeding rollers (11, 12) at a feeding rate which deviates from the speed of the cutter (16), for adaption of the cutting length of the fibre thread.</p> |
