Frequently Asked Questions | FAQs
What is the function of flyer in speed frame?
In the speed frame machine used in the textile industry, the flyer has several important functions.
One of the main functions of the flyer is to twist the roving, which is a bundle of fibers that has been carded and drawn to prepare it for spinning. The flyer rotates at high speed and creates a rotating motion that twists the roving as it passes through the machine. This twisting action is what transforms the loose fibers of the roving into a strong, continuous yarn.
Another function of the flyer is to guide the yarn as it is spun. The flyer has a small hook or eyelet at the end that catches the yarn and guides it onto the bobbin. The rotation of the flyer also helps to draw the yarn out and create tension, which is important for producing a consistent yarn with a uniform thickness.
The flyer also helps to control the speed and tension of the spinning process. By adjusting the speed of the flyer and the tension on the roving, the operator can control the thickness and strength of the yarn being produced.
Overall, the flyer plays a critical role in the spinning process, helping to twist the roving, guide the yarn, and control the speed and tension to produce a high-quality yarn.
