Abstract
(DE)
Die Erfindung betrifft eine Vorrichtung zum Aufbringen eines fließfähigen Mediums (5) auf eine kontinuierlich transportierte Bahn (4), wobei das Medium (5) durch eine kontinuierlich drehende Übertragungswalze, beispielsweise durch eine am Umfang mit Gravurrillen (12) versehene Gravurwalze (11), auf die Bahn (4) übertragbar ist; wobei ein Auftragskopf (10) vorgesehen ist, um das fließfähige Medium (5) auf den Umfang der Gravurwalze (11) zu übertragen; wobei der Auftragskopf (10) eine zum Umfang der Gravurwalze (11) hin offene Kammer (13) mit einem Einlass (14) und einem Auslass (15) für das aufzutragende Medium (5) aufweist; und wobei die Kammer (13) an ihrer in Drehrichtung vorderen Außenseite durch eine vordere Rakel (16) und an ihrer in Drehrichtung hinteren Außenseite durch eine hintere Rakel (18) begrenzt ist, die beide dichtend am Umfang der Gravurwalze (11) anliegen. Sie zeichnet sich dadurch aus, dass die vordere Rakel (16) durch einen Anpresskörper (24) mit einstellbarer Anpresskraft an den Umfang der Gravurwalze (11) andrückbar ist.
(EN)
The invention relates to a device for applying a free-flowing medium (5) to a continuously conveyed web (4), wherein the medium (5) can be transferred to the web (4) by means of a continuously rotating transfer roll, for example a gravure roll (11) provided with gravure grooves (12) on the circumference; wherein an application head (10) is provided in order to transfer the free-flowing medium (5) to the circumference of the gravure roll (11); wherein the application head (10) comprises a chamber (13) which is open toward the circumference of the gravure roll (11) and has an inlet (14) and an outlet (15) for the medium (5) to be applied; and wherein the front outer face, in the direction of rotation, of the chamber (13) is delimited by a front doctor blade (16) and the rear outer face, in the direction of rotation, is delimited by a rear doctor blade (18), both doctor blades being healingly seated against the circumference of the gravure roll (11). The device is characterized in that the front doctor blade (16) can be pressed against the circumference of the gravure roll (11) by means of a pressing body (24) with an adjustable pressing force.
(FR)
L'invention concerne un dispositif d'application d'une substance coulante (5) sur une bande (4) transportée en continu, la substance (5) pouvant être transférée sur la bande (4) par un rouleau de transfert tournant en continu, par exemple par un rouleau de gravure (11) muni sur la périphérie de rainures de gravure (12). Selon l'invention, une tête d'application (10) est destinée à transférer la substance coulante (5) sur la périphérie du rouleau de gravure (11) ; la tête d'application (10) comporte une chambre (13) ouverte vers la périphérie du rouleau de gravure (11) et munie d'une entrée (14) et d'une sortie (15) pour la substance (5) à appliquer ; et la chambre (13) est limitée, sur son côté extérieur avant dans la direction de rotation, par une racle avant (16) et, sur son côté extérieur arrière dans la direction de rotation, par une racle arrière (18), les deux racles reposant de manière étanche sur la périphérie du rouleau de gravure (11). Le dispositif se caractérise en ce que la racle avant (16) peut être pressée contre la périphérie du rouleau de gravure (11) par un corps presseur (24) à l'aide d'une force de pression réglable.
