  • Method and installation for the production of a condensed nonwoven and condenser device
    Patent number: 6732412
    Abstract: So as to produce a condensed nonwoven, at least one first nonwoven is produced with the aid of a carding machine (1), said first nonwoven issued from the carding machine is directed to a rotating transfer element (20) by means of one first transport surface (S1), and said first nonwoven is transferred onto a second transport surface (S2) by means of said transfer element (20), the second transport surface (S2) being driven at a linear speed (V2) slower than the circumferential speed of the transfer element (20). In the transfer zone between the two transport surfaces (S1) and (S2), the first nonwoven is preferably kept against the surface of the transfer element (20) by means of suction. Application: production of heavy condensed nonwovens, especially having a weight of more than 80 g/m2.
