Description

82100258-3 2 dagens teknik är att basmaterialet kräver mindre malning och lägre mängder avvattningsförsvårande kortfibriga massor för att uppnå samma ytfinish och ytstyrka. Fördelen med detta är att för kartong förbättras dess böj- styvhet genom en större tjocklek och genom att ytornas elastícitetsmouui ökar. 82100258-3 2 today's technology is that the base material requires less grinding and lower amounts of dewatering-difficult short-fiber pulps to achieve the same surface finish and surface strength. The advantage of this is that for cardboard its flexural stiffness is improved by a greater thickness and by increasing the elasticity of the surfaces.

Uppfinningen är icke begränsad till de nämnda påfüringsmetoderna, utan kan varieras inom uppfinníngstankens ram.The invention is not limited to the mentioned application methods, but can be varied within the scope of the inventive idea.
