AI Technical Summary
In existing twisting machines, the yarn's position on the bobbin changes during the twisting process, resulting in uneven stretching distance. This may cause the yarn to be pulled out too much or become loose, affecting the quality of the twisted yarn.
The yarn is squeezed by the first and second pressure rollers, which converts the yarn tension into the driving force of the pressure rollers, keeping the yarn taut in the twisting machine and preventing it from loosening.
It effectively solves the problem of yarn loosening caused by uneven stretching during the twisting process, ensuring that the twisted yarn quality meets the requirements.
