Abrégé
(DE) Die Erfindung betrifft ein Verfahren zur Herstellung einer gestrichenen, mehrlagigen Faserstoffbahn, insbesondere Verpackungspapier- oder Kartonbahn bei dem zunächst ein Stoffstrom erzeugt wird, der danach nacheinander mindestens einem Stoffauflauf, mindestens einer Siebpartie zur Bildung einer mehrlagigen Faserstoffbahn, einer Pressenpartie, einer Trockenpartie und anschließend einer Aufrollung zugeführt wird, wobei auf die mehrlagig hergestellte Faserstoffbahn mindestens eine weiße Strichschicht mit Hilfe wenigstens eines an sich bekannten Vorhang-Auftragswerkes (12.1) aufgebracht wird und die Bahn vor dieser Beschichtung einer an sich bekannten Kondensations-Presstrocknung (9) unterzogen wird.
(EN) The invention relates to a method for producing a coated multilayer fibrous web, in particular a packaging paper or cardboard web. First, a material flow is produced which is then successively fed to at least one headbox, at least one wire section for forming a multilayer fibrous web, a pressing section, a drying section, and subsequently a roll-up device. At least one white coating layer is applied onto the fibrous web that is produced in a multilayer manner using at least one curtain application unit (12.1), which is known per se, and the web undergoes a condensation press drying (9), which is known per se, prior to said coating.
(FR) L'invention concerne un procédé de production d'une bande fibreuse multicouche enduite, notamment une bande de papier d'emballage ou de carton, selon lequel est tout d'abord produit un courant de pâte, ledit courant de pâte étant ensuite acheminé jusqu'à au moins une caisse de tête, au moins une partie toile métallique pour la formation d'une bande fibreuse multicouche, une partie presse, une partie de séchage et enfin un dispositif d'enroulage; au moins une couche blanche étant appliquée sur la bande fibreuse produite en multicouche à l'aide d'au moins une coucheuse à rideau (12.1) connue en soi et, avant ce couchage, la bande étant soumise à un séchage par condensation/pressage (9) connu en soi.
