The main function of a roving machine is drafting and twisting, and winding the roving into a certain package to meet the processing requirements of the ring spinning machine. Roving machines are divided into flyer roving machines and roller drafting roving machines according to the twisting mechanism. The flyer roving machine continuously applies twist to the yarn strand through the rotation of the flyer, producing twisted roving. The roller drafting roving machine clamps and twists the yarn strand with a pair of drafting rollers, forming alternating positive and negative twists on the yarn strand to produce untwisted roving. Both flyer roving machines and roller drafting roving machines can be further divided into first pass, second pass, and single pass roving machines. The feeding form, roving package, and number of spindles of various roving machines differ, but the machine structure and function are roughly the same.
