Title (EN) METHOD FOR COATING A MATERIAL WEB
(FR) PROCÉDÉ DE REVÊTEMENT D'UNE BANDE DE MATÉRIAU
(DE) VERFAHREN ZUR BESCHICHTUNG EINER MATERIALBAHN
Abstract:
(EN) The invention relates to a method for coating a material web (2), in particular a fibrous web, by means of a coating device, the coating device (1) having an application unit (3) for applying a coating medium to the material web and having an enclosure (4), and the application unit being arranged in the interior of the enclosure and the enclosure having a first opening for the entering of the material web and a second opening for the exiting of the material web, characterized that in the interior of the enclosure a positive pressure greater than the ambient pressure outside the enclosure is produced during the coating so that air flows from the interior of the enclosure to outside (5b) of the enclosure through the first opening and/or the second opening.
(FR) La présente invention concerne un procédé pour recouvrir une bande de matériau (2), en particulier de matériau fibreux, au moyen d'un dispositif de revêtement, ledit dispositif de revêtement (1) présentant un agrégat de revêtement (3) pour déposer un agent de revêtement sur la bande de matériau ainsi qu'un compartiment (4) et l'agrégat de revêtement étant placé à l'intérieur du compartiment et le compartiment présentant une première ouverture pour l'admission de la bande de matériau et une seconde ouverture pour la sortie de la bande de matériau. L'invention est caractérisée en ce que, pendant le revêtement de l'intérieur du compartiment, une pression positive est générée, laquelle est supérieure à la pression ambiante régnant à l'extérieur du compartiment, de telle sorte que l'air provenant de l'intérieur du compartiment s'écoule par la première et/ou la seconde ouverture depuis le compartiment vers l'extérieur (5b).
(DE) Verfahren zur Beschichtung einer Materialbahn (2) insbesondere einer Faserst off bahn mittels einer Beschichtungsvorrichtung, wobei die Beschichtungsvorrichtung (1) ein Auftragsaggregat (3) zum Auftrag eines Beschichtungsmediums auf die Materialbahn sowie eine Umhausung (4) aufweist, und wobei das Auftragsaggregat im Inneren der Umhausung angeordnet ist und die Umhausung eine erste Öffnung zum Einlauf der Materialbahn sowie eine zweite Öffnung zum Austritt der Materialbahn aufweist, dadurch gekennzeichnet, dass während der Beschichtung im Inneren der Umhausung ein Überdruck erzeugt wird, der größer ist, als der Umgebungsdruck außerhalb der Umhausung, so dass Luft aus dem Inneren der Umhausung durch die erste und/oder die zweite Öffnung aus der Umhausung nach außerhalb(5b) strömt.
