Description
Einrichtung für Tiefdruckmaschinen zum Kühlen der verdruckten Farbe Es ist bekannt, bei Tiefdruckmaschinen die auf das Papier aufgedruckte Farbe zu kühlen, um eine bessere Farbwirkung zu erzielen. Zu diesem Zweck wird der gedruckte Bogen zunächst einer Heizvorrichtung und dann einer Kühlvorrichtung, einem Kühlzylinder o. dgl., zugeführt, der Kühlwasser zugeführt wird. Es hat sich nun durch Versuche ergeben, daß die Farbwirkung wesentlich günstiger wird, wenn man die verdruckte Farbe stark unterkühlt, als wenn man mit Kühlwasser von gewöhnlicher Zimmer- oder Leitungstemperatur arbeitet. Man verbindet daher erfindungsgemäß den Kühlzylinder der Maschine, auf dem der Bogen nach dem Bedrucken und nach der Heizung aufgebracht wird, mit einer besonderen Kühlanlage, in der das Kühlmittel -Wasser, Sole, Luft o. dgl. - in an sich bekannter Weise auf eine wesentlich tiefere Temperatur gebracht und dem Kühlzylinder zugeführt wird.Equipment for gravure printing machines for cooling the printed color It is known that the color printed on the paper can be used in gravure printing machines cool to achieve a better color effect. For this purpose the printed Arch first a heating device and then a cooling device, a cooling cylinder o. The like., The cooling water is supplied. It has now been tried through show that the color effect is much cheaper if you print it Color is strongly subcooled, as if you were using cooling water from ordinary room or Line temperature is working. According to the invention, therefore, the cooling cylinder is connected the machine on which the sheet is applied after printing and after heating with a special cooling system in which the coolant - water, brine, air or the like - brought to a much lower temperature in a manner known per se and fed to the cooling cylinder.
Die Zeichnung zeigt ein Ausführungsbeispiel dieses Gedankens, und zwar stellen dar: Abb. i eine Tiefdruckmaschine in Draufsicht, wobei der Druckzylinder um 9o° versetzt gezeichnet ist, und Abb. 2 einen Schnitt.The drawing shows an embodiment of this idea, and although show: Fig. i a rotogravure printing machine in plan view, with the printing cylinder is drawn offset by 90 °, and Fig. 2 is a section.
Der von dem Druckzylinder a kommende bedruckte Bogen wird von den Greifern b der Ausführtr ommel c übernommen und dem Wendezylinder d übergeben, der mit Heizvorrichtungen versehen ist und zugleich als Trockentrommel dient. Die Greifer dieses Wendezylinders übergeben den bedruckten Bogen der zweiten Hälfte e der Ausfuhrtrommel c, die gleichfalls mit Greifern f und außerdem mit Hohlräumen g versehen ist, denen das Kühlwasser von der hohlen Zylinderwelle h aus durch die Rohre i zugeleitet wird. Mit der Tiefdruckmaschine ist eine besondere Kühlanlage k verbunden; in dieser wird das Kühlmittel - Wasser, Sole, Luft o. dgl. -auf eine tiefere Temperatur gebracht und mittels der Leitungen l der hohlen Welle h des Kühlzylinders c zugeführt und nach Durchfließen der Kühlräume g wieder zur Kühlanlage k zurückgeleitet. Die Kühlvorrichtung c bildet also zusammen mit der Kühlanlage k und den Kühlmittelleitungen l einen geschlossenen Kreislauf.The printed sheet coming from the impression cylinder a is taken over by the grippers b of the execution drum c and transferred to the turning cylinder d, which is provided with heating devices and also serves as a drying drum. The grippers of this turning cylinder transfer the printed sheet to the second half e of the export drum c, which is also provided with grippers f and also with cavities g, to which the cooling water is fed from the hollow cylinder shaft h through the tubes i. A special cooling system k is connected to the gravure printing machine; In this the coolant - water, brine, air or the like - is brought to a lower temperature and fed to the hollow shaft h of the cooling cylinder c by means of the lines l and, after flowing through the cooling spaces g, returned to the cooling system k. The cooling device c thus forms a closed circuit together with the cooling system k and the coolant lines l.
Die Zeichnung zeigt den Erfindungsgedanken in Anwendung auf eine Bogendruckmaschine. Der Erfindungsgedanke ist selbstverständlich nicht auf diese Art von Maschinen beschränkt, sondern kann auch auf andere Tiefdruckmaschinen angewendet werden, also in erster Linie auf Maschinen, die von der Rolle drucken.The drawing shows the idea of the invention applied to a sheet-fed printing press. The idea of the invention is of course not limited to this type of machine, but can also be applied to other gravure printing machines, so primarily Line on machines that print from the roll.
