Process to eliminate yarn breakage in ring spinning machine - by sucking non-spun slubbing into yarn breakage suction pipe and attaching it to yarn

摘要

Process involves sucking slubbing not spun into a yarn into a yarn breakage suction pipe. The slubbing is sucked onto a yarn to be attached by means of a slubbing sucking device of a yarn attaching unit that moves along the work stations of the ring spinning machine. For the purpose of maintaining of the optimum ratio of the suction effect of the slubbing sucking nozzle to the suction effect of the yarn breakage suction pipes associated with the individual work stations, the height of the suction effect of the nozzle is controlled in accordance with the distance between the prevailing operating area of the yarn attaching device and the suction generator of the ring spinning machine. USE/ADVANTAGE - For automatic elimination of yarn breakages on a ring spinning machine. The process and associated installation increase the success quota of the joining processes and the quality of the joints.
