Description

（４）上記したいずれかの形態のフィラメントワインディング装置において、前記繊維束案内体は、前記供給を受けた前記繊維束の幅より拡幅の凹状をなして該凹状の底面にて前記繊維束と繊維長手方向に沿って接触し、該接触した繊維束を案内すると共に、前記凹状の底面の中央域を前記繊維長手方向に沿った凸条とし、該凸条の両側を下降傾斜面とするようにできる。こうすれば、上下に重ねた積層繊維束の状態で給糸ローラーから繊維束案内体まで送り出された繊維束は、繊維束案内体がなす凹状の底面に接触することで、中央域が凸条でその両側が下降傾斜面の凹状底面に倣うよう更に拡幅する。よって、この形態のフィラメントワインディング装置によれば、繊維巻回対象物の外表面の繊維束巻回軌跡をより幅広とできる。しかも、凹状底面に倣った繊維束の拡幅は、凹状の両端凸部位にて制限されるので、拡幅後の繊維束の形状安定化が可能となり、巻回品質の向上にも寄与できる。 (4) In any one of the above-described filament winding apparatuses, the fiber bundle guide body has a concave shape wider than the width of the supplied fiber bundle, and the fiber bundle and the fiber are formed on the bottom surface of the concave shape. contacts in the longitudinal direction, as well as guides the fiber bundle was the contact, and the concave ridge along the central region before Symbol fiber length side direction of the bottom surface, the both sides of the convex strip and the descending inclined surface You can In this way, the fiber bundle fed from the yarn feeding roller to the fiber bundle guide body in the state of laminated fiber bundles stacked one above the other is in contact with the concave bottom surface formed by the fiber bundle guide body, so that the central region is convex. Then, both sides are further widened so as to follow the concave bottom surface of the descending inclined surface. Therefore, according to the filament winding apparatus of this embodiment, the fiber bundle winding locus on the outer surface of the fiber winding object can be made wider. Moreover, since the widening of the fiber bundle following the concave bottom surface is limited by the concave convex portions at both ends, it becomes possible to stabilize the shape of the fiber bundle after widening and contribute to the improvement of the winding quality.
