An apparatus on a carding machine has a covering comprising work and cover elements lying opposite the clothing of a high-speed cylinder. There is, in succession, an air exhaust opening for the exit of air and an opening for entry of air, past which openings a flow of fibres and air is passed. To allow improved detachment and elimination of short fibres in a simple manner, the spacing of the covering upstream of the exhaust opening is smaller than the spacing of the covering between air exhaust opening and air inlet opening and an airflow flows against the direction of rotation of the cylinder along the surface of the cylinder and flows with short fibres through the air exhaust opening.
An apparatus on a carding machine having a clothed cylinder and a covering arrangement lying opposite the clothing of the cylinder, wherein the covering arrangement comprises one or more work elements and one or more cover elements, and further comprises, arranged in succession in the direction of rotation of the cylinder, an air exhaust opening, and an air inlet opening, wherein the spacing between the covering arrangement and the cylinder upstream of the air exit opening is smaller than the spacing between the covering arrangement and the cylinder at a position between the air exhaust opening and the air inlet opening.
An apparatus on a flat card or roller card for textile fibres such as cotton, synthetic fibres or the like, in which a covering comprising work and cover elements lies opposite the clothing of a high-speed cylinder, in which, viewed in the direction of rotation of the cylinder, in succession there is an opening for the exit of air (exhaust airflow) and an opening for entry of air (supply airflow), past which openings a flow of fibres and air is passed, wherein, in relation to the cylinder, the spacing of the covering upstream of the exhaust air opening and the spacing of the covering downstream of the exhaust air opening are different, wherein in relation to the cylinder the spacing of the covering upstream of the exhaust opening is smaller than the spacing of the covering between exhaust air opening and supply air opening and an air flow that detaches short fibres from the flow of fibres flows along the surface of the cylinder against the direction of rotation of the cylinder and flows away with the short fibres through the exhaust air opening.
