Method and arrangement for the production of a wood-free coated, matte or semi-matte paper web

Abstract

An arrangement for the production of a wood-free coated, matte or semi-matte paper web including at least one precalendering apparatus for precalendering the paper web, at least one coating apparatus and at least one dryer. The coating apparatus is configured to apply a liquid and/or a pasty application medium to the paper web. The dryer is configured for drying the paper web.

1 . An arrangement for the production of a wood-free coated, matte or semi-matte paper web, comprising:
 at least one precalendering apparatus for precalendering the paper web;   at least one coating apparatus for applying one of a liquid and pasty application medium to the paper web; and   at least one dryer for drying the paper web.   
   
   
       2 . The arrangement of  claim 1 , wherein said at least one coating apparatus includes a first coating apparatus and a second coating apparatus, said at least one dryer including a first dryer and a second dryer, the paper web moving in a running direction L, said second coating apparatus and said second dryer being upstream from said at least one precalendering apparatus in said running direction L. 
   
   
       3 . The arrangement of  claim 2 , wherein said at least one precalendering apparatus includes at least one of a smoothing unit, a soft calender with at least one nip, a super calender with at least one nip and a shoe calender with at least one extended nip. 
   
   
       4 . The arrangement of  claim 3 , wherein said at least one precalendering apparatus is said smoothing unit having two hard-cast rollers, which together form a nip. 
   
   
       5 . The arrangement of  claim 3 , wherein said at least one precalendering apparatus is said soft calender having one hard-cast roller and one roller equipped with a plastic covering, which together form a nip. 
   
   
       6 . The arrangement of  claim 3 , wherein said at least one precalendering apparatus is said super calender having one hard-cast roller and one paper roller, which together form a nip. 
   
   
       7 . The arrangement of  claim 1 , wherein said at least one coating apparatus is one of which makes contact with the paper web and one which works in a non-contact mode. 
   
   
       8 . The arrangement of  claim 7 , wherein said at least one coating apparatus is one of a jet flow coating device and a film coating device. 
   
   
       9 . The arrangement of  claim 7 , wherein said at least one coating apparatus is one of a curtain coating device and a spray coating device. 
   
   
       10 . The arrangement of  claim 1 , wherein said at least one dryer is at least one of an impingement dryer and an IR drying unit. 
   
   
       11 . The arrangement of  claim 1 , further comprising at least one film press arranged in a running direction (L) of the paper web upstream from at least one of said at least one precalendering apparatus and said at least one coating apparatus. 
   
   
       12 . The arrangement of  claim 1 , wherein the arrangement forms a unit with a paper machine. 
   
   
       13 . The arrangement of  claim 1 , wherein nether a smoothing nor a calendering apparatus is arranged, in a running direction L of the paper web, upstream from said precalendering apparatus and said coating apparatus.
