摘要:
The invention relates to an inspection device (42) for checking the position of at least one coating on a blank (1) transported through a converting machine (10). The inspection device comprising a camera (49) configured to capture an image of a portion of the blank provided with a reference mark (30) comprising at least one coating, An optical axis (A) of the camera is arranged at first angle (φ) in relation to a vertical axis (V) defined by a normal vector (N) of a surface of the blank (1). An illumination system (50) is configured to emit incident light rays towards a measuring point (Pm) on the blank 1. The incident light rays from the illumination system are directed to the reference mark and specular reflected light rays from the reference mark are captured by the camera.

Die Erfindung betrifft ein Auftragaggregat (400; 600; 800), das ein Auftragwerk (414; 614; 814) mit Gegendruckzylinder (408; 608; 808), Formzylinder (402; 602; 802), Versorgungswalze (403; 603; 803) und Positioniervorrichtung (43) aufweist,wobei die Positioniervorrichtung (43) eine Linearführung (07)und einen Haupttragkörper (06) aufweist,der durch die Linearführung (07) geführt in einer Stellrichtung (B) bewegbar angeordnet ist und mittels eines Wälzlagers (26) an dem Haupttragkörper (06) rotierbar angeordnet ist und wobei die Positioniervorrichtung (43) einen Transfertragkörper (19) aufweist,der durch die Linearführung (07) geführt in der Stellrichtung (B) relativ zu dem Haupttragkörper (06) bewegbar angeordnet ist und wobei an dem Transfertragkörper (19) ein Bestandteil (47) einer Lageraufnahme (44) angeordnet ist, die zur Aufnahme eines an der Versorgungswalze (403; 603; 803) angeordneten Wälzlagers (27) ausgebildet istund wobei die Positioniervorrichtung (43) einen Vorratstragkörper(57) aufweist,der durch die Linearführung (07) geführt in der Stellrichtung (B) sowohl relativ zu dem Haupttragkörper (06) als auch relativ zu dem Transfertragkörper (19) bewegbar angeordnet ist und wobei an dem Vorratstragkörper (57) ein Zwischenspeicher (404; 604; 804) für Auftragfluid angeordnet ist und wobei der Vorratstragkörper (57) in der Stellrichtung (B) gesehen zumindest teilweise zwischen dem Haupttragkörper (06) und dem Transfertragkörper (19) angeordnet ist.
摘要:
An inking system (450) for use in transferring ink to a flexographic printing plate in a flexographic printing system includes an anilox member (452) having an ink transfer zone (420) located between first and second recessed bearing contact zones (440, 442). A radius of the recessed bearing contact zones is less than a radius of the ink transfer zone by at least 0.100 inches. An ink tray (460) includes a floor (461) and first and second end walls (462, 464). Bearings (470, 472) are mounted outside of the end walls which engage with the first and second bearing contact zones (440, 442), respectively, thereby positioning the ink tray assembly (454) in a specified position relative to the anilox member (452). Upper edges (466, 468) of the end walls (462, 464) extend into the recessed bearing contact zones.
摘要:
The present disclosure relates to a flexographic printing device and a method of simultaneously printing at least two material webs having different thicknesses in the printing device. The flexographic printing device comprises a printing unit comprising a printing roller carrying on a surface thereof an image to be printed, an impression roller and an anilox roller adapted to feed printing ink from a printing ink chamber onto the printing cliché mounted on the printing roller. The printing unit is configured for simultaneously printing at least two material webs having different thicknesses, by means of adjusting the radial extension of the surface of the printing roller, impression cylinder and/ anilox roller in respect of the material web to be printed.
