摘要：
A card cover less carding surfaces, comprising an air-flow channel of regular cross-section disposed transverse the carding surface of a card cylinder, axially parallel and radially open thereto. The channel of the card cover when supplied with a stream of air from an external air-flow inducing means acts to move fiber in a helical path across and around on operating card cylinder.
