A process by which woollen cloths are divested of the oil they imbibe by the operation of carding, and the texture at the same time rendered much closer, firmer, and stronger. This process, also called milling, is per formed by a mill, thence called a fulling mill, the machinery of which consists of a number of wooden stampers or beetles, working in a large trough by means of cams or wipers on the shaft of a water wheel. The cloths are laid in the trough, and a quantity of warm water, in which is put a portion of fuller's earth or soap, being poured upon it, it is subjected to the action of the stampers, the repeated blows of which cause the fibres to felt and combine more closely together. After a time it is taken out, and the grease and filth wrung therefrom, and again returned to the fulling mill, from which it is occasionally taken to be stretched, and to undo the plaits it has acquired in the trough. When it is sufficiently milled and brought to the quality and thickness desired, it is scoured in the trough in clear water until perfectly clean, after which it is hung upon tenter-hooks to dry.
