  • Patent number: 4299011
    Abstract: A card is equipped behind the doffer roll (7) with a pair of delivery rolls (8, 8a) for the web (9) provided each with a stationary grazing blade (12, 12a) for seed particles or similar impurities. Between the nip line K of the delivery rolls (8, 8a) and the grazing blades (12) of the delivery roll (8) a web deflecting roll (15) is supported rotatably and drivable in the same rotational direction as the delivery roll (8). The web deflecting device (15) is arranged of, but in the vicinity of, the normal free web exit path (9a) and brings a web (9b) possibly clinging to the delivery roll (8) and carried on thereon back to the normal web exit path (9a) and separates the web (9b) from impurities on the cylindrical surface. The impurities are only subsequently mechanically eliminated by the grazing blade (12), in such manner that the cleaning operation for the delivery roll (8) is effected in two subsequent separate cleaning steps.
