The carding machine, with revolving flats and carding-flat bars with clothing, has a sliding guide surface (20) for the ends of the carding-flat bars where the flats are moved by a continuous drive belt. The convex zone of the sliding guide (20) can be shifted (A,B) on the underlay surface (17) in the peripheral direction. The ends of the convex zone (20) have an interlocking fit with the ends of the concave deflection zone. The concave zone of the sliding guide (20) has a wedge shape, where the sliding (20b) and underlay (17a) surfaces are wedge shaped against each other. The underlay surface has a groove to take part of the sliding guide. The sliding guide (20) is of a plastics material which is pliable, wear-resistant and has a low friction rating. The lower angled base surface (20b) of the sliding guide (20) works together with a chamfered underlay surface (17a). The deflection zone is fixed, and its ends are outside the working area of the carding-flat bars (14,14a,14b). The ends of the deflection zone are at the side members of a U-shaped carrier, which is mounted to the machine frame with a penetration outside the working area of the carding-flat bars (14,14a,14b). The U-shaped carrier has two flat side walls, and a flat base, with an extension at each side wall. The sliding guide (20) extends over the end surfaces of the U-shaped carrier, which support the guide (20) with its sliding surface (20a) on the base of the carrier. The sliding surface (20a) of the guide (20) extends at least partially over the side walls of the carrier. The sliding guide (20) is under the concave deflector, with the ends of the guide overlapping with the ends of the deflector, with the guide ends on the deflector ends. The end of the sliding guide is tensed against the end of the deflection zone, through a spring. The sliding guide (20) can be shifted by about 100 mm. Its shift (a) in the radial direction (r1) is 0.01-0.03 mm. An additional sliding guide is over the surface of the sliding guide (20), which can be shifted to move its sliding surface of the wedge structure by 0.2-4.0 mm in a radial direction. The carding-flat bars (14,14a,14b) are taken over the carrier and deflector by the sliding guide (20).
