The airlay card mod. D works on the same principle of the airlay card mod C.
In addition to the standard top + bottom air suctions in exit, the airlay card in this version is equipped with a doffing system similar to the one of traditional roller cards.
The doffing system allows to produce light weight nonwoven products, as low as 20 gsm, suitable for the furniture and filtration sector, as well as to feed vertical lapping systems.
The air formation and doffer formation can be used separately – to produce purely airlaid or purely carded webs – or simultaneously, to produce sandwich nonwovens with hybrid properties.
feeding the Vertical lapper
The light weight webs that can be produced in the configuration fpd, make the airlay system MULTIline suitable to feed vertical lappers.
Our vertical lapper FIBERwave arranges the light-weight airlaid web in vertical waves thanks to a set of rotating discs.
A switch apron allows to send light-weight airlay carded webs in the vertical lapper, or to pass underneath the vertical lapper with standard airlaid fabrics of any basis weight.
