Abstract
It is an object of the present invention to provide a hairiness controlling device that can start, simultaneously with the start of spun yarn running, stabilizing a spun yarn run through disks. According to the present invention, a rotation speed of each disk 6 is varied depending on a running speed of a spun yarn Y run as a drive drum D rotates, thereby setting the tension of the spun yarn Y at an appropriate value when the spun yarn starts to run.
Claims4
A hairiness controlling device for rotating a plurality of disks to falsely twist a spun yarn run through the disks while applying a feeding force to the spun yarn, the hairiness controlling device comprising a means for controlling the rotation of the plurality of disks which provides for simultaneously varying the rotational speed of each of said disks, depending on a running speed of said spun yarn, with the start of running of said spun yarn.
