Spliced joint of spun yarn and method for producing same

摘要

Broken ends of a spun yarn are introduced into a hole of an air nozzle device from upper end and lower end of the hole respectively and the yarns are doubled. The doubled yarns are slightly slacked and subjected to air jetting by the air nozzle device to produce a spliced joint. The distribution of twists inherent of spun yarns is changed in the region of the spliced joint by twists imparted to the yarns by the air jet nozzle and at least one fixed portion of the new twist distribution is formed in the spliced joint.
