Document Type and Number:
Japanese Patent JPH0367951
Kind Code:
B2
Abstract:
This invention relates to a procedure for splicing yarns, whether textile or otherwise, with a join made by coupling two single untwisted yarns and thereafter retwisting them, wherein the single yarns are untwisted beyond a substantially nil twist value and are then coupled and retwisted so as to impart to the single yarns a desired twist at least the same as the twist comprised in the original yarn, the untwisting phase being carried on beyond the nil value until a negative twist value has been imparted which is equal to at least 15-20% of the initial twist value comprised in the single yarn, and the value of the negative twist being at least in proportion to the desired reciprocal thrust induced between the yarns at least in the transitory phase when the fibers are parallel to the axis of the single coupled yarns during retwisting. The invention also relates to a splice made by the above procedure.
