Working Principle:

1. First, we have to hang the roving package in the creel.
2. From roving package roving pass through the two roving roller guides.
3. Then roving goes through trumpet which has a funnel shape and guides the roving to the drafting roller.
4. After passing from a trumpet the roving goes through three sets of drafting roller, front roller, middle roller, and back roller. The apron is used here for smooth drafting. After drafting, roving got the shape of yarn but there is no twist in it.
5.   Then the yarn goes through a lappet eye which is used as a guide and guides the yarn to the traveler and ring cup. Here the required twist is given to the yarn to make it strong. The separator is used to separate the yarn from another yarn.
6. Then Yarn wound to the bobbin.
