Abstract
A device for producing a fibrous web, in particular a tissue web, includes a first press having a first felt and a second felt, both of which are guided through a press nip of the first press. A Yankee cylinder dries the fibrous web and a transfer press transfers the fibrous web to the Yankee cylinder. The second felt is also guided through a press nip of the transfer press. A paper-contacting side of the second felt is formed of a nonwoven layer which includes at least 80 wt. %, in particular at least 90 wt. % of nonwoven fibers formed of polyamide or polyamides and having a fineness of 6.7 dtex or less, in particular 3.3 dtex or less. An associated method for producing a fibrous web, in particular a tissue web, is also provided.
