cylinder clothing 4 a as a result of carding work especially in the case of a high production rate and or the processing of synthetic fibres or of cotton synthetic fibre blends the cylinder wall 4 e undergoes expansion that is to say the radius r 3 increases and the carding nip a decreases the heat is directed via the cylinder wall 4 e into the radial carrying elements the cylinder ends 4 c and 4 d the cylinder ends 4 c 4 d likewise undergo expansion as a result thereof that is to say the radius increases the cylinder 4 is almost entirely encased enclosed on all sides u2014 in a radial direction by the elements 14 23 37 see fig1 and to the two sides of the flat card by the elements 17 a 17 b 19 a 19 b 24 a 24 b as a result scarcely any heat is radiated from the cylinder 4 to the outside to the atmosphere nevertheless the heat of the cylinder ends 4 c 4 d of large surface area is especially conveyed by means of radiation to the side screens 19 a 19 b of large surface area to a considerable extent from where the heat is radiated out to the colder atmosphere as a result of that radiation the expansion of the side screens 19 a 19 b is less than that of the cylinder ends 4 c 4 d which results in a reduction in the carding nip a fig2 a that ranges from undesirable in terms of the result of carding to hazardous the carding elements card top bars 14 are mounted on the flexible bends 17 a 17 b and the fixed carding.
