Abstract

Abstract A method and apparatus wherein a machine for carding cotton, man-made fibres and mixtures thereof is provided with a trash removing device usually in the form of a longitudinally fluted roller that cooperates mechanically with a roller clothed with flat-topped card-clothing. The flat-topped clothing roller may be a taker-in roller located in a feed section and the fluted roller is set close to the flat-topped card-clothed roller whereby it is adapted to remove trash projecting above the teeth on the flat-topped card-clothed roller. The trash removing roller is provided with a cowling spaced radially from the periphery of the roller and providing a longitudinally extending gap part way around the roller. A radial lip extends along the one edge of the cowling substantially closing the gap. A deflector lip projects into the gap so as to deflect material travelling in the space between the trash removing roller and the cowling out through the gap.
