Abstract (en)
[origin: EP0431379A1] The invention relates to a method and an apparatus for cleaning or carding textile fibres between a rotating cleaning or carding drum (2), having a clothing (7) provided fixedly on this and carding elements (5) which surround this drum and on which a clothing (9, 10, 11, 12, 13, 14) is likewise provided. <??>The essence of the invention is that the teeth (9, 10, 11, 12, 13, 14) of the carding elements (5) are provided differently in the direction of movement (8) of the rotating drum (2), in such a way that, for example, the tooth (9) has a so-called negative direction of relatively large angle alpha and the tooth (14) a positive direction of relatively small angle alpha , and those located in between according to Figure 3 are provided with different angles of incidence. This ensures a cleaning or carding effect which differs within a predetermined circumferential region of the drum.
