ABSTRACT:
In the high speed driving of a ring spinning frame provided with a plurality of ring-spinning twisting-winding units, to compensate for the possible loss of thickness of yarn produced, when the drive speed of the spindles reaches more than a predetermined rotation speed, such as 16,000 rpm in the case of spinning a cotton yarn of 40's, a total draft ratio of each drafting part of the ring spinning frame is regulated to maintain the expected yarn count according to a predetermined compensation program.
