Abstract
The present invention is designed to wind a long continuous fiber around a rotor and to cut the fiber in prescribed lengths by blades positioned at intervals on the circumference of a rotor. Scrapers rotate together with the rotor in order to scrape out the cut fibers displaced between the blades in accordance with the reciprocal movement of the rotor in the axial direction. The use of scrapers makes it possible to prevent the over packing of the cut fibers disposed between the blades, as seen in the case of conventional apparatuses, and to forcibly discharge the cut fibers from between the blades. Consequently, the cutting ability improves remarkably, specifically in cases where the fiber to be cut is especially short.
