DEVICE FOR GUIDING YARN END OF YARN FEEDING BOBBIN, AND BOBBIN PREPARATION SYSTEM

摘要

This device for guiding a yarn end of a yarn supply bobbin includes an air injection device and a guide section (33). The air injection device injects air from a nozzle. The guide section (33) has a guide hole section (36), gaps (38), and a notch (37). The guide hole section (36) passes through the guide section (33), in alignment with the orientation of the nozzle. The gaps (38) are in communication with the guide hole section (36) and are perpendicular to a centerline (36c) of the guide hole section (36). The guide hole section (36) is configured to arrange a plurality of guide plates (34) having a first opening (34a) respectively in the order from the largest-diameter to smallest-diameter first openings (34a). The size of the first opening (34a) of the guide plate (34) on the side far from the nozzle is smaller than that of the first opening (34a) of the guide plate (34) on the opposite side therefrom.
