Title
(DE) VERFAHREN ZUM STRUKTURIEREN EINES PRESSBANDES
(EN) METHOD FOR STRUCTURING A PRESS BELT
(FR) PROCÉDÉ POUR STRUCTURER UNE COURROIE DE PRESSE
Abstract
(DE) Ein Verfahren zum Strukturieren eines Pressbandes (5) aus Metall welches Oberflächenbereiche mit auf Dekorplatten zu übertragenden dreidimensionalen Prägestrukturen (6) aufweist, wobei auf eine Außenfläche des Pressbandes (5) eine Beschichtung aufgetragen wird und sodann die Prägestrukturen (6) durch Ab-/ oder Auftragen von Material von unbeschichteten Bereichen des Pressbandes (5) erzeugt werden, wobei das Auftragen der Beschichtung mittels eines digital gesteuerten Druckverfahrens erfolgt, bei welchem die Beschichtung in Tropfenform aufgetragen wird, wobei vor dem strukturieren der Pressbänder (5) die Länge und Breite der Prägestrukturen (6) unter Berücksichtigung einer zu erwartenden Dehnung des Pressbandes (5) in einem Betriebszustand ermittelt werden.
(EN) The invention relates to a method for structuring a press belt (5) made of metal, which has surface areas having three-dimensional embossed structures (6) to be transferred to decorative panels, wherein a coating is applied to an outer face of the press belt (5) and the embossed structures (6) are then produced by abrading or applying material from uncoated regions of the press belt (5), wherein the application of the coating is carried out by means of a digitally controlled printing method in which the coating is applied in droplet form, wherein before the press belts (5) are structured the length and width of the embossed structures (6) are determined, taking into account an anticipated elongation of the press belt (5) in an operative state.
(FR) L'invention concerne un procédé pour la structuration d'une courroie de presse (5) en métal qui présente des zones surfaciques dotées de structures en relief (6) tridimensionnelles à transférer sur des panneaux décoratifs, un revêtement étant appliqué sur une surface extérieure de la courroie de presse (5) et les structures en relief (6) étant ensuite produites par élimination de matière de zones non revêtues de la courroie de presse (5)ou application de matière sur celles-ci, l'application du revêtement ayant lieu au moyen d'un procédé d'impression commandé de manière numérique dans lequel le revêtement est appliqué sous forme de gouttes. La longueur et la largeur des structures en relief (6) sont déterminées en tenant compte d'une dilatation à prévoir de la courroie de presse (5) dans un état de fonctionnement avant la structuration de la courroie de presse (5).
