Pneumafil: During roving and spinning (for ring spinning), some fibers cannot join yarn or roving body. Hence, parts that could not join the body are dropped and formed fiber fly. These fibers are sucked by pneumatic systems that are placed after delivery rollers and they are collected in the machine. Moreover, if end breaks happen in yarn or roving, the same system collects flowing fibers after leaving delivery rollers until operators intervention.The waste fibers formed in this process are called pneumafil.

Roving:A Roving is a long and narrow bundle of fiber. Rovings are produced during the process of making spun yarn from fine quality raw cotton. After carding and combing, the fibers lie roughly parallel in smooth bundles. These are drawn out, by hand or machine, and slightly twisted to form longer material suitable for spinning.
