CARD CLOTHING BACKGROUND OF THE INVENTION 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.
Previously such card clothing was formed of nonalloyed steel and attempts to achieve the desired hardness were made by varying the carbon content of the steel. Yet a certain hardness could not be exceeded since otherwise the material becomes brittle.
SUMMARY OF THE INVENTION Hence it is a primary object of the present invention to provide card clothing having increased longevity of use and which can be operated at greater speeds than heretofore possible.
Now in order to implement the aforementioned object and others which will become more readily apparent as the description proceeds the card clothing of the present invention is formed of alloyed steel.
DETAILED DESCRIPTION OF THE INVENTION As explained above an essential aspect of this development resides in forming the clothing from an alloyed steel. It has been found that in contrast to prior attempts at influencing the hardness of the clothing through the carbon content, it is possible to obtain higher hardness values, up to 1,200 Vickers hardness, with alloyed steels and with increased tensile strength of the material.
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.
In consideration of the previously discussed properties of the card clothing of this invention it ispossible to employ advantageously clothing formed completely a of alloyed steel at high output cards.
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.
It is also possible that 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.
On the average there can be realized with the indicated alloys hardness values, based on a Vickers diamond pyramid hardness test, of approximately 980 with increased toughness of the material, so that card clothing formed of such materials exhibit increased longevity and simultaneously increased card efficiency.
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.
Of course, the previously disclosed alloys contain the usual amounts of traces of phosphorous and sulphur.
