Abstract
PURPOSE: To provide the subject method comprising the steps of causing once a turning air stream to act on both yarn ends, to intertwist both yarn ends, thereafter to pull both yarn ends and to cause the turning air stream to act thereon thereby to improve the tightness of fibers at the joint and to imcrease the yarn strength without thickening the joint of yarns.
CONSTITUTION: In joining the yarn, when a relay pipe A firstly attracts and holds the yarn end of a cone spool C and turns the same up to a position indicated by chain line, a yarn keeper 12 turns around a shaft 11 as a fulcrum and a lower yarn YL is bent as shown by dotted line in a space between a nozzle 1 and a yarn guide plate 7. Then, when a suction mouth B attracts and holds the yarn end of a package P and turns the same up to a position indicated by chain line to insert a upper yarn YU between guides 6 and 7, the upper yarn is thereafter bent between the nozzle 1 and the yarn guide plate 6. In this state, yarn keepers 9a and 9b are released, and thereafter pressure air is injected through an injection tube directed to a yarn insertion hole 21 to generate a turning air stream withih the hole 21. Then, the above described yarn keepers are restored back to the original state to regenerate a turning air stream, thus completing the yarn joining operation.
