The ring spinning frame, commonly called the ring, is the conventional spinning system. It transforms the roving from the roving frame into spun yarn using the operations of: -Drawing -Twisting -Winding The ring frame developed from the throstle frame, a descendant of Arkwright's water frame. Ring spinning is a continuous process. Drafting Mechanism To attenuate roving until the desired fineness is reached.
Consolidation(strength) Mechanism To impart strength to the fiber by twisting it.
Winding and Package forming Mechanism To wind up the resulting yarn in a package suitable for storage, transportation and further processing.

To wind up the twisted strand (yarn) in a form suitable for storage, transportation and further processing. Drafting arrangement is the most important part of the machine. It influences mainly evenness and strength The following points are therefore very important drafting type design of drafting system. drafting settings. selection of drafting elements like cots, aprong, traveller etc. choice of appropriate draft. service and maintenance.
A good ring in operation should have the following features: best quality raw material good, but not too high, surface smoothness an even surface exact roundness good, even surface hardness, higher than that of the traveller should have been run in as per ring manufacturers requirement long operating life correct relationship between ring and bobbin tube diameters perfectly horizontal position it should be exactly centered relative to the spindle 1.
