Abstract (en)
[origin: EP2009151A1] A fiber bundle guide surface of an introduction channel 32 is configured to include a first surface 78 ranging from an inlet 70 side of the introduction channel 32 to an outlet 71 of the introduction channel 32, a second surface 79 connected to the first surface 78 at a downstream side of a swirling direction of a swirling airflow and ranging from the inlet 70 side to the outlet 71, and a third surface 80 connected to the second surface 79 at the downstream side of the swirling direction and ranging from the inlet 70 to the outlet 71. Each of an angle between the first surface 78 and the second surface 79 and an angle between the second surface 79 and the third surface 80 is set to be almost right angle. If a fiber bundle fed from a draft device is introduced into the introduction channel 32, the fiber bundle is sharply bent and surely constrained by the introduction member, thereby making it difficult to separate fibers from the fiber bundle and making it possible to reduce fibers causing fiber loss ( Fig.3 ).
