ABSTRACT:
An apparatus on a textile machine for cleaning fiber material has a first roller for conveying a travelling fiber web, and second and third rollers which have respective nips with one another and with the first roller on rotation of the three rollers. The second roller is arranged downstream of the third roller and co-operates with the first roller so that fiber is detached, the fiber is transferred to the nip with the third roller and conveyed by the third roller to the nip with the first roller. The rollers have clothing with tips which are inclined in the direction of rotation. To improve the cleaning the front angle α of the tips of the second roller is about from 10° to 50° and the clothing gaps may be large to obtain a higher filling volume for fibers.
