Aerodynamic Carding Technology

All Autefa Solutions web forming and random carding machines utilise the aerodynamic principle, which results in a three dimensional fiber orientation and total randomisation. Total fiber randomisation provides the isotropic web strength required by our customers. Therefore, the aerodynamic principle represents the key to maximum product quality, economy and reliability from a single source 

Aerodynamic Web Forming Machine Airlay Card K12-direct

The Airlay Card K12-direct utilises an aerodynamic principle which results in three-dimensional fiber orientation and total randomisation. Total fiber randomisation enables isotropic web strength. Depending on the type of material the entering mat of fibers may come from a volumetric hopper feeder or a pneumatic chute feeder.

The Aerodynamic Web Forming Machine Airlay Card K12-direct is a further development of the well-proven Fehrer Random Card V21/R – K12 of which more than 500 units have been sold and installed all over the world.

The standard Airlay Card K12-direct may be equipped with a deflecting unit to randomize the fibers as they are in flight from the main cylinder to the collecting surface and alternatively, with the High Loft device for producing webs with greater loft due to more vertical fiber orientation.
