Flexible card clothing

Flexible card clothing

Since 1879 BIOTTI card clothing has specialized in the production of flexible card clothing for woollen and worsted carding machines.
With the constant modernization and updating of our plant and production techniques, we have become leaders in the manufacturing of high quality card clothing, which is now sold and appreciated by customers all over the world.
Thanks to years of experience we can offer first-rate and reliable products, as well as technical assistance in choosing and mounting the various types of card clothing onto our client’s machinery.

The choice of flexible card clothing depends on a number of factors and to obtain optimum spinning results we always ask our customers what type of material is to be introduced into the carding machine and the resulting NM.
Once supplied with this information and a diagram or detailed description of the machine, we can then suggest the best combination of foundation and steel-wire necessary to produce the most efficient carding.
Since the choice of card clothing depends on so many different factors, we don’t rely on standardized charts but examine every individual case, so as to determine the best possible technical solution to fit each customers needs.
