Abstract: A carding machine includes a main carding cylinder having a cylinder axis and a cylinder clothing; and traveling flats cooperating with the main carding cylinder along a circumferential length portion thereof. The traveling flats include a plurality of flat bars each having a flat bar clothing cooperating with the cylinder clothing; and a drive for moving the flat bars in unison in an endless path having a working leg in which the flat bar clothings cooperate with the cylinder clothing and a return leg. The working leg extends circumferentially about a portion of the main carding cylinder. The carding machine further has a flexible bend having a convex surface and being supported on the machine frame laterally of the main carding cylinder; and a slide guide supported on the flexible bend. The slide guide has a convex surface supporting the flat bars for sliding motion thereon along the working leg. The radial position of the convex surface of the slide guide relative to the cylinder axis determines the radial clothing point distance between the clothing points of the flat bar clothings and the clothing points of the cylinder clothing. Further, an adjusting device is provided for radially displacing the slide guide such that the radial clothing point distance remains uniform at all locations along the working leg.
