Title
(EN) A METHOD AND A PAPER MACHINE LINE FOR THE MANUFACTURE OF COATED FINE PAPER
(FR) PROCEDE DE FABRICATION DE PAPIER FIN COUCHE ET LIGNE DE FABRICATION DE PAPIER FIN COUCHE
Abstract
(EN)
The present invention relates a method for the manufacture of paper, in particular of coated fine paper, in which method paper stock is fed from a headbox (100) to a wire section (200) in which water is drained from a paper web (W), in which method the paper web (W) is passed from the wire section (200) to a press section (300) to press water out of the paper web (W), and in which method, after the press section (300), the paper web (W) is dried in a dryer section (400), precalendered and coated in a coating station (600), after which the paper web (W) is dried in a drying section (650) and calendered in a final calender (900), and reeled in a reel-up (1000). In the method the stock is fed into the headbox (100) using multilayering technology, the paper web (W) is precalendered in a one or more reinforced-nip calender (500), the paper web (W) is coated in a film coating unit. The invention also relates to a paper machine line in particular for the manufacture of coated fine paper, which line comprises a headbox (100), a wire section (200), a press section (300), a dryer section (400), a precalender (500), a coating station (600) and drying section (680), a final calender (900) and a reel-up (1000). The paper machine line comprises multilayer headbox (100), a one or more reinforced-nip precalender (500), film coating station (600).
(FR)
L'invention concerne un procédé de fabrication de papier, en particulier, de papier fin couché, ce qui consiste à transmettre la pâte à papier depuis la caisse de tête (100) jusqu'à une table plate (200) au niveau de laquelle l'eau est extraite du papier sous forme de bande (W), puis à transférer la bande de papier (W) depuis la table plate (200) jusqu'à une presse (3) afin d'extraire par pression l'eau de la bande de papier (W), à transférer la bande de papier de la presse (300) à un séchoir (400) afin de la sécher, à effectuer un calandrage préalable et à coucher la bande de papier dans un dispositif de couchage (600), à sécher la bande de papier dans un séchoir (650), à la calandrer dans une calandreuse finale (900) et à l'enrouler dans une bobineuse (1000). D'après ce procédé, on introduit la pâte à papier dans la caisse de tête (100) au moyen d'une technique de mise en couche multiple, on effectue le précalandrage de la bande de papier dans une calandreuse (500) comportant un ou plusieurs rouleaux à pincements renforcés et on couche la bande de papier dans un ensemble de couchage sous forme de pellicule. L'invention concerne également une ligne de fabrication de papier constituée par plusieurs machines servant, en particulier, à fabriquer du papier fin couché, cette ligne de fabrication comprenant une caisse de tête (100), une table plate (200), une presse (300), un séchoir (400), une précalandreuse (500), un dispositif de couchage (600), un séchoir (680), une calandreuse finale (900) et une bobineuse (1000). Cette ligne de fabrication est composée d'une caisse de tête multicouche (100), d'une précalandreuse (500) comportant un ou plusieurs rouleaux à pincements renforcés et d'un ensemble de couchage pelliculaire (600).
