Abstract

PURPOSE:To obtain a good package with no cob-webbing in high-speed winding by providing yarn restricting guide bars for preventing the release of yarns near both ends of a driver stroke between upper and lower directions of the first and second traverse means. CONSTITUTION:Guide bars 15R and 15L are fitted to brackets 11R and 11L respectively so that yarns conveyed by vanes 16R, 16L, 17R and 17L from the traverse end to the center between the first and second traverses are applied against the direction to be released from the vanes 16R, 16L, 17R and 17L. Tips of the guide bars 15R and 15L are molded in a dogleg shape so that the yarns conveyed from the center of the traverse to ends can be easily guided. The guide bars 15R and 15L are coupled with the yarns at least before and after the yarns are released from the vanes 17R and 17L and prevent the yarns from being swayed in the X and Y directions and conveyed to the first traverse when the yarns are traversed. As a result, the positions where the yarns are released from the vanes 17R and 17L are stabilized, and cob-webbing can be prevented.
