Combing
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.
In general there are two main systems of preparing fiber for yarn: the worsted system and the woollen system. The worsted system is defined by the removal of short fibers by combing and top preparation by gilling. In the woollen system short fibers are retained, and it may or may not involve combing.
Description
The circular combs used have long metal teeth, and only barely resemble the comb used on hair. However, they are used in a similar fashion with one comb holding the fiber, which is slowly dubbed in by a brush, while the other is moved through, slowly transferring the fiber to the moving comb.
