Abstract

Die Erfindung betrifft eine Schabervorrichtung (1), umfassend eine Schaberklinge (2) zum Zusammenwirken mit einer bewegbaren Oberfläche (6), eine Halteeinrichtung (3) für die Schaberklinge, eine Einrichtung (5) zur Erzeugung eines Anpressdruckes zur Anpressung der Schaberklinge (2) an die bewegbare Oberfläche (6) und eine Einrichtung (8) zur wenigstens mittelbaren Erfassung einer die Anpresskraft und/oder den Anpressdruck über zumindest einen Teilbereich der Erstreckung der Schaberklinge (2) wenigstens mittelbar charakterisierenden Größe. Die Erfindung betrifft ferner eine Rakelvorrichtung, umfassend eine Klinge zum Vergleichmäßigen eines Mediums auf einer bewegbaren Oberfläche, eine Halteeinrichtung für die Klinge, eine Einrichtung zur Erzeugung eines Druckes zur Positionierung der Klinge gegenüber der bewegbaren Oberfläche und eine Einrichtung zur wenigstens mittelbaren Erfassung einer die Anpresskraft über zumindest einen Teilbereich der Erstreckung der Klinge wenigstens mittelbar beschreibenden Größe. Die Einrichtung (8) zur wenigstens mittelbaren Erfassung einer die Anpresskraft und/oder den Anpressdruck wenigstens mittelbar charakterisierenden Größe umfasst zumindest einen piezoelektrischen Sensor (9, 9.1 bis 9.n, 9.1, 9.21, 9.22, 9.31 bis 9.3n, 9.41, 9.42, 9.5).

The invention relates to a scraper device (1) comprising a scraper blade (2) for interacting with a movable surface (6), a holding device (3) for the scraper blade, a device (5) for generating a contact pressure for pressing the scraper blade (2). to the movable surface (6) and a device (8) for at least indirect detection of a pressing force and / or the contact pressure over at least a portion of the extension of the doctor blade (2) at least indirectly characterizing size. The invention further relates to a squeegee device comprising a blade for equalizing a medium on a movable surface, a holding device for the blade, means for generating a pressure for positioning the blade relative to the movable surface and means for at least indirectly detecting a contact force at least a portion of the extension of the blade at least indirectly descriptive size. The device (8) for the at least indirect detection of a size which at least indirectly characterizes the contact force and / or the contact pressure comprises at least one piezoelectric sensor (9, 9.1 to 9.n, 9.1, 9.21, 9.22, 9.31 to 9.3n, 9.41, 9.42, 9.5).
