Abstract
Apparatus for cutting fibrous reinforcement material in relationship with an ejector nozzle. The apparatus comprises at least two feeding rollers and a rotary cutter which is provided with a substantially cylindrical mantle surface with attachments for a number of knives. These cooperate with a support roller with an elastic surface layer for forming a thread nip. The mantle surface of the cutter is provided with slot-shaped recesses for the fiber thread, which recesses extend peripherally along the mantle surface and between successive knives. The recesses enable the thread to be fed forward by means of the feeding rollers at a feeding rate which deviates from the speed of the cutter, for adaptation of the cutting length of the fiber thread.
