Paper machine

Abstract

The invention relates to a paper machine for the production of a paper, board, tissue or other fibrous web ( 2 ), comprising a press section ( 1 ) having at least one press nip and comprising an impingement dryer ( 13 ) arranged immediately after the press section. The invention is characterized in that the paper machine has an applicator ( 17 ) for applying a coating color in the manner of a curtain ( 21 ) or for the film application ( 26 ) of coating color or for spraying ( 31 ) coating color on.

1 . A paper machine for the production of a paper, board, tissue or other fibrous web ( 2 ), comprising a press section ( 1 ) having at least one press nip and comprising an impingement dryer ( 13 ) arranged immediately after the press section, 
 characterized in that    the paper machine has an applicator ( 17 ) for applying a coating color in the manner of a curtain ( 21 ) or for the film application ( 26 ) of coating color or for spraying ( 31 ) coating color on.    
   
   
       2 . The paper machine as claimed in  claim 1 , 
 characterized in that    it comprises a press section ( 1 ) having at least one press nip, an impingement dryer ( 13 ) arranged immediately after the press section ( 1 ), a first part of a drying section ( 34 . 1 ), an applicator ( 17 ) for applying a coating color in the manner of a curtain ( 21 ) or for the film application ( 26 ) of coating color or for spraying ( 31 ) coating color on, and then a second part of a drying section ( 34 . 1 ).
