The drafting section of the roving frame may be 3 over 3 or 4 over 4 with or without apron roller arrangement. Only the 3-over-3 or 4 over 4 roller with double apron drafting system are still to be found in modern machines offered by manufacturers. In general 3/3 drafting system is used, but for higher draft applications 4/4 drafting system is used.

Yarn number is a measure of the fineness or size of a yarn expressed either as mass per unit length or length per unit. Yarn Count and Yarn Size are synonymous with Yarn Number.There are two systems of expressing yarn number or yarn count. ❶ Direct yarn numbering system (mass/unit length) ❷ Indirect yarn numbering system (length/unit mass)

In a very general way, a fiber is defined as any product capable of being woven or otherwise made into a fabric. It may be thought of as the smallest visible unit of textile production. Fibers may be agricultural products (such as cotton or wool) or units (such as nylon or polyester) manufactured in a chemical plant. Fibers than serve as the raw material in the next stage of textile manufacturing.

Top rollers are held strictly parallel to and in perfect alignment with bottom rollers.//The bottom rollers of speed frame exercise immense influence on the quality of roving.//The flyer is a special component of the roving frame that helps to insert twist in the roving. The flyer speeds employed normally range from about 1000 to 1400 rpm. The flyers’ special shape offers less air resistance, preventing roving breakages.
