carding cylinder 3 with the aid of an insertion device with insertion fitting or shoe 6 the fibers 2 are guided as fiber bundles in the circumferential direction while resting on the surface and in the longitudinal direction of the main carding cylinder 3 the sectional detail of carding machine 1 shown in fig2 shows that the fibers 2 are guided between the surface of the main carding cylinder 3 and the clothing 8 that is positioned on the fronts of flat bars 7 the flat bars 7 are positioned on the carding machine the flat bars 7 are arranged as traveling flat assemblies on the carding track 4 one after another and at a short distance to each other the longitudinal axes of flat bars 7 extend in the longitudinal direction of the main carding cylinder 3 the dimensions for clothing 8 are approximately the same as for the flat bars 7 and the clothing is composed of strip type elongated web like material layers 9 with comb structures 10 projecting from the top the comb structures 10 are metal needle combs which extend across nearly the complete surface of clothing 8 the comb structures 10 engage in the fibers 2 that are guided on the main carding cylinder 3 as a result the fibers are combed in the circumferential direction of the main carding cylinder 3 and are thus aligned parallel according to the invention fastening means are provided for securing the clothing 8 to the flat bars 7 which means are reversibly detachable thus these means can preferably be fastened and released repeatedly from the flat bars with the aid of simple tools for this the clothing 8 is not mounted directly on the flat bars 7 rather the clothing.
