Abstract
Eine Beschichtungsvorrichtung (1) zum Beschichten von Druckbogen (2) mit einem Fluid umfasst einen Zylinder (3) und eine Bogentransporteinrichtung (4), die zusammen einen Druckspalt (5) bilden, wobei der Zylinder (3) einen Blasluftkanal (6) zum in oder nach dem Druckspalt (5) erfolgenden Ablösen des Druckbogens (2) vom Zylinder (3) hat.A coating device (1) for coating printed sheets (2) with a fluid comprises a cylinder (3) and a sheet transport device (4) which together form a pressure nip (5), wherein the cylinder (3) has a blast air duct (6) for injecting or after the printing nip (5) taking place detachment of the printing sheet (2) from the cylinder (3).
Description
Die vorliegende Erfindung betrifft eine Beschichtungsvorrichtung zum Beschichten von Druckbogen mit einem Fluid, umfassend einen Zylinder und eine Bogentransporteinrichtung, die zusammen einen Druckspalt bilden. The present invention relates to a coating apparatus for coating printed sheets with a fluid, comprising a cylinder and a sheet transport device, which together form a pressure nip.
In der
Bei Beschichtungsvorrichtungen kann das Problem des Nachlaufens des Druckbogens auftreten, wobei der Druckbogen aufgrund der Klebrigkeit des Fluids auf dem Zylinder an diesem haften bleibt. In the case of coating devices, the problem of the tracing of the printed sheet may occur, whereby the printed sheet will adhere to it due to the stickiness of the fluid on the cylinder.
Der Erfindung liegt die Aufgabe zugrunde, eine Beschichtungsvorrichtung zu schaffen, bei der das Nachlaufen sicher vermieden wird. The invention has for its object to provide a coating device in which the tracking is reliably avoided.
Diese Aufgabe wird durch eine Beschichtungsvorrichtung zum Beschichten von Druckbogen mit einem Fluid gelöst, die einen Zylinder und eine Bogentransporteinrichtung umfasst, die zusammen einen Druckspalt bilden, wobei der Zylinder einen Blasluftkanal zum in oder nach dem Druckspalt erfolgenden Ablösen des Druckbogens von dem Zylinder hat. This object is achieved by a coating apparatus for coating printed sheets with a fluid which comprises a cylinder and a sheet transport device which together form a printing nip, the cylinder having a blast air channel for detaching the printed sheet from the cylinder in or after the printing nip.
Durch die aus dem Blasluftkanal ausgestoßene Druckluft wird der Druckbogen von dem dabei das Fluid auf den Bogen übertragenden Zylinder weg gedrängt, wodurch das Nachlaufen sicher vermieden wird. As a result of the compressed air expelled from the blast air channel, the printed sheet is forced away by the cylinder which transfers the fluid to the sheet, thereby reliably avoiding run-on.
Ein Zusatzvorteil ist, dass die Erfindung bei steifen Kartonbogen und weniger steifen Papierbogen gleichermaßen gut funktioniert. An added benefit is that the invention works equally well on stiff cardboard sheets and less stiff paper sheets.
Weiterbildungen der Erfindung ergeben sich aus der folgenden Beschreibung von Ausführungsbeispielen und der dazugehörigen Zeichnung, worin zeigt: Further developments of the invention will become apparent from the following description of embodiments and the accompanying drawings, wherein:
