Abstract (en)
[origin: EP2006427A2] A fiber bundle concentrating apparatus includes a guide member (31) having a pair of guide surfaces (35a) which face each other and guide a fiber bundle so that the width of the fiber bundle is narrowed, and an excitation device (32) for vibrating the guide member to generate sound pressure. The guide member includes a pair of guide portions (35) which are placed to face each other, so that the guide surfaces are formed. Each guide portion has a straight portion (35b) and a tapered portion, which are made continuous by a connection portion. The straight portions are formed so that the distance between the two guide surfaces is constant, and the tapered portions are formed so that the distance between the two guide surfaces gradually becomes greater toward a direction opposite to the advancing direction of the fiber bundle. The straight portions (35b) form an outlet (35d) through which the fiber bundle is fed out from the guide member. The shape of the guide portions is set so that when the guide member is vibrated at a predetermined frequency by the excitation device, the outlet (35d) and the connection portions (35e) are located in locations different from the nodes of vibration.
