Definitions

• the present invention relates to improvements in card clothing.
• Such clothing is especially employed as sawtooth covers for card cylinders. They serve to process fiber material and thus come into engagement with counter elements.
• the card clothing of the present invention is formed of alloyed steel.
• Clothing formed in the manner taught by the invention possesses increased longevity and, in other words, with average good nep values can process up to 500 tons staple fiber material formed of natural fibers as well as fibers formed of natural and synthetic polymers.
• a further advantage which can be realized with the present invention resides in the drastic reduction in the grinding required during the life of the card clothing. It is possible to considerably increase the intervals between the grinding operations owing to the increased service life of the clothing.
• alloys particularly suitable as the alloys are those containing 0.3 to 2.0 by weight carbon, 0.05 to 2.25 by weight silicon, 0.05 to 2.0 by weight manganese, 0.01 to 2.0 by weight vanadium, with the remainder iron.
• the vanadium can be replaced by 0.01 to 3.5 by weight tungsten.
• the aforementioned alloys can also contain both vanadium and tungsten in the indicated amounts and, if desired, additionally can contain 0.001 to 3.0 by weight boron.
• the aforementioned alloys further contain 0.05 to 4.5 by weight chromium or tita- Similarly it has been found to be advantageous if there is added to one of the previously indicated combination of components 0.05 to 3.5 by weight nickel.
• a particularly advantageous alloy contains, for instance, 0.5 to 0.6 by weight carbon, 0.5 to 0.8 by weight manganese, 1.2 to 1.6 by weight silicon, and 0.5 to 0.8 by weight chromium.
• the clothing disclosed herein can be particularly advantageously employed for carding at carding machines.
• the clothing contains one or a number of wireshaped structures having a sawtooth profile, the wireshaped structures consisting of one of the aforementioned alloys.
• the previously disclosed alloys contain the usual amounts of traces of phosphorous and sulphur.
• alloyed steel having a sawtooth profile formed of alloyed steel wherein the alloy contains 0.3 to 2.0 percent by weight of carbon, 0.05 to 2.5 percent by weight silicon, 0.05 to 2.0 percent by weight manganese and 0.01 to 3.5 percent by weight tungsten, said alloyed steel having a hardness substantially higher than that of the corresponding non-alloyed steel and up to about 1200 based on the Vickers hardness test.
