Problem solved Roving Frame Workflow and Related Calculation

[fyitester]

Roving frames are crucial pieces of cotton mill production machinery that are used in the processing of combed sliver for spinning into yarn. The final phase in spinning preparation is roving manufacture.
The tasks of the roving production

(1) Drafting the sliver to a finer one whose weight per unit length is made to allow a draft at the ring frame in the approximate range of 4 to 12;

(2) Using two suspended flyers to inserting few twists to the roving to make it strong enough to sustain the tension in further processing;

(3) Winding roving into the bobbin in proper way.
