In a clothing support for a card flat covering, the belt-shaped support is made of plastics material, and there is embedded in a base body at least one reinforcing insert which is also belt-shaped and which is arranged in the vicinity of the back of the support. In order to make possible stronger anchoring by simple means and to allow undisrupted oscillation of clothing wires, the base body has at least two layers (bottom layer and top layer) of different plastics materials connected to one another, and the bottom layer incorporates a fabric.

An apparatus on a textile machine for cleaning fibre material has a first roller for conveying a fibre 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 third roller and so co-operates with the first roller that fibre is opened and detached, the fibre is transferred to the nip with the third roller and is conveyed by the third roller to the nip with the first roller, where it is transferred back to the first roller. To improve the degree of cleaning upstream of the second roller and third there is arranged at least one fixed carding element in which the teeth of the clothing are inclined opposite to the direction of rotation of the first roller.
