ABSTRACT OF THE DISCLOSURE The invention is a method and apparatus for carding cotton, man- made textile fibres or a mixture of cotton and man-made textile fibres in a carding machine. The method comprises the steps of: feeding the fibres to a first roller having flat-topped card-clothing, whereby the fibres are carried forward on said first roller; subsequently pulling at least some of the fibres on said first roller into said flat-topped card-clothing thereon by means of a second card-clothed roller or a brush roller co-operating with said first roller at a position beyond that at which the fibres are fed to said first roller, having regard to the direction of motion of said first roller, whereby at least some of the trash carried by said fibres is left exposed on the flat tops of said flat-topped card-clothing; subjecting the exposed trash on said first roller to the beating action of a trash removing device co- operating with said first roller; removing the fibres from said first roller, and subjecting the fibres to a card action between a card-clothed cylinder and at least one card-clothed plate or flat. In a preferred embodiment the then free trash and dust are sucked from the card-clothing on the roller. The method and apparatus removes trash, including "micro-dust" from the fibrous material fed to the carding machine.
