Title:
YARN WINDING MACHINE
Document Type and Number:
Japanese Patent JP2005231823
Kind Code:
A
Abstract:

To resume winding while giving tensile force for suppressing kinky thread to joined yarns when traverse width is large.

This yarn winding machine is provided with a yarn joining device 17 provided with a yarn guide channel 47 on a winding side, a suction mouth 18 for forming a lower yarn passage R2 between a winding part 12 and it, and a yarn bring-close lever 49 for guiding the lower yarn passage R2 into the yarn guide channel 47 on the winding side. A left side yarn bring-close guide 55 and a right side yarn bring-close guide 56 are arranged between the yarn joining device 17 and the winding part 12. The yarn bring-close guides 55, 56 can advance and retract freely from each stand-by position K on the left and right outer sides of the lower yarn passage R2 having traverse width W before moving to the yarn guide channel 47 on the winding side to each advance position L forming one lower yarn passage R2 in front of the yarn guide channel 47 on the winding side. They advance after forming the lower yarn passage R2 by the suction mouth 18, come into contact with a yarn passage R until the winding part 12 after joining yarns reaches predetermined winding speed to give tensile force for suppressing kinky thread, and retract after the winding part 12 reaches the predetermined winding speed.
