Combing is a method for preparing carded fiber for spinning. Combing is divided into linear and circular combing. The Noble comb is an example of circular combing. The French comb is an example of linear combing. The process of combing is accompanied by gilling, a process of evening out carded or combed top making it suitable for spinning. Combing separates out short fibers by means of a rotating ring or rectilinear row of steel pins. The fibers in the 'top' it produces, have been straightened and lie parallel to each other. When combing wool, the discarded short fibers are called noils, and are ground up into shoddy.
