Top making is unique to the worsted system of wool manufacturing, and is not carried out in the woollen system. The top-making process comprises three main steps, which includes Carding, Gilling and Combing.

The top-making stage essentially prepares the wool for the spinning process, at which the wool is formed into a yarn, ensuring: the wool fibres are thoroughly blended to form a homogenous mixture. At this point, all fibres are parallel to each other, short fibres and contaminants have been removed.
