Sheets of card, of different qualities, used for carding wool.
[The card for cotton wool is a peculiar instrument, formed of a leather foundation, in which are inserted large numbers of minute wire teeth. Cards are employed for the purpose of straightening out the fibres of cotton wool into a uniform sheet or lap. In cotton machinery, the card is applied to the surface of a wooden drum, which acts upon similar drums, and which presents the cotton in a smooth and uniform sheet -of great slenderness. In some ingenious machines the leather is cut, perforated; the wire bent, cut, and inserted by automatic arrangements.— R. E.]
