9. This carding and stripping, once done by hand, is now done in the mill by a power machine called the card. (See picture, Textiles, page [38].) Notice that instead of cards this machine consists of rollers or cylinders. Some are carding cylinders and some are stripping cylinders. The principle is the same as that of the hand cards. The wool is carded and stripped again and again and is finally delivered in a soft, fluffy rope called a sliver ready for drawing and spinning.
