About Ring spinning frame:
Spinning is the final step of yearn manufacturing process. The working procedure of ring spinning frame is taking the roving comes from simplex and produced yarn by reducing the weight of unit length. Ring is attached around bobbin. The traveler rolling on ring and enfold the yarn on bobbin. Ring spinning frame plays the vital role to spinning the yarn so it is called Ring spinning frame. Ring spinning frame’s production system is conventional.
Technical specification of modern ring frame
Ring frame is only one machine which can produce yarn by any kind of fiber. Basically the working system of ring spinning frame is easy and the cost of machine is a little cheap. It is easy to separate the bobbin from ring and easy to carry. but a few problem also reduce its popularity like, working speed, conventional system, large amount of electricity consumption. please follow the link to know more about rotor spinning frame and ring spinning frame.
