Abstract
This is a fancy yarn spinning device with the number of counts and twisting varying according to the variation of waveforms, designed with pre-defined waveforms, working with fixed cycles, fixed amplitudes, or random cycles, and random amplitudes, which serve as drafting and twisting parameters for the ring spinning machine. This device involves a servomotor and a inverter, for respective control of the revolutions of front, middle, and rear rollers of the ring spinning machine and the spindle, so the drafting rate and twisting of all areas of the ring spinning machine can change continuously with pre-defined settings, to produce yarns with variable number of counts and twisted conditions. The design of variable waveforms can also achieve different touch and visual feelings. Compared with the conventional models that can only produce slub yarns with drastic change of counts, or twisted yarns with simplified twist changes, this device combines the features of the two, and is capable of producing new yarn types with more variations, better hand touch and better comfort.
