Background

The false twisting is that two ends of a rope are fixed, the twisting is carried out in the middle, one side is twisted more and more, the other side is also twisted more and more, but the twisting direction is opposite, so the total twisting number on the rope is not changed and is still 0, and the false twisting is called. The false twisting machine is a machine for false twisting of ropes.

The false twisting machine has a base, on which three driven shafts are mounted, on which a plurality of friction disks are arranged, the shafts being arranged in a triangle so that the friction disks overlap in the center of the triangle. The threads are guided through the overlap region on the periphery of the friction discs, so that each disc acts on the threads to match the twist. To deform the smooth yarn, the friction discs must be driven at a high circumferential speed in order to twist the thread sufficiently. The shaft is thus driven at high rotational speeds of up to 20000U/min. If the installation of the rotating shaft is deviated, the rotating shaft and the friction discs are greatly shaken, so that the distance between the friction discs is changed, and the false twisting of the yarns by the friction discs is influenced. In this respect, a new false twisting machine is designed.
