Abstract
A card is provided with a cover assembly adapted to provide enhanced cleaning efficiency. The cover is 4 covers in one with each part being set at a prescribed distance from the carding cylinder to induce increased cleaning. Air drawn through a gap at the first cover disturbs and intermingles with the fibers and loosen dirt. The fourth cover exerts centripetal action to strip away waste from the fiber.
