2) An implement used for ‘teasing’ or working wool into a sliver.
In this sense the word ‘card’ derives ultimately from the Latin word for thistle, and the cards used originally in the dressing proces were teasel heads set in a wooden frame. Later the hand-cards were used in pairs and were effectively wire brushes: they have been described as having sharpened and bent iron staples set in a piece of leather, mounted on a wooden back with a handle. The term is on record from the fourteenth century: 1382 cardes and kammes [combs], Yeadon
