<p>There are provided at least a rotary blade body (A) having a plurality of rotary blades, a stationary blade body (B) having a guide (7) for guiding a length of strand toward the rotary blades in a direction along a rotating axis of the rotary blades and a stationary blade (7c) disposed at the tip of the guide, take-up rollers (1, 2) disposed in a position on a root side of the guide, and a casing receiving these elements. The respective rotary blades comprise a blade plate (5) having a blade edge at its one end. The respective blade plates are disposed radially on a rotating shaft in a manner to position the blade edges thereof closest to the stationary blade in the same rotary plane and retreat in an inclined state increasingly away from the stationary blade from the blade edge toward a base portion thereof. <IMAGE></p> |
