Abstract

Beneath the rubber blanket is a self-adhesive sheet (6) extending from in front of the start of the pattern being printed up to behind the end of the pattern being printed. The edges (8,9) of the sheet are cut obliquely in the axial direction (7) of the cylinder (1), so as to produce a parallel program surface or trapezium shaped surface.

Description

Die Erfindung betrifft einen gummituchbespannten Zylinder in Druckmaschinen.The invention relates to a blanket-covered cylinder in printing machines.

Es sind gummituchbespannte Zylinder bekannt (DD 33 137), die mit einer im Kanalbereich des Zylinders angeordneten Anlaufkante versehen sind. Dadurch soll vermieden werden, dass die vorhandenen Zylinderkanäle bei der Rotation der zugeordneten Walzen in der Spaltstelle zu einer dynamischen Anregung der Maschine füh­ ren, da sich Kraftvektoren in Betrag und Richtung innerhalb kurzer Zeit ändern. Die Herstellung der Anlaufkante ist kostenaufwendig und ist nicht für alle Anwendungsfälle und insbesondere nicht zur Behebung von Druckschwierigkeiten vor Ort geeignet. Dabei wird unter dem Begriff Zylinder sowohl Zylinder im klassischen Sinne, wie z. B. Offset­ zylinder, aber auch gummituchbezogene Walzen, wie z. B. Farbauftragwalzen verstanden.There are known blanket-covered cylinders (DD 33 137), which have a in the channel area of the cylinder arranged leading edge are provided. This is to avoid that the existing cylinder channels during the rotation of the assigned rollers in the nip point to a dynamic excitation of the machine ren because force vectors change in magnitude and direction within a short time. The manufacture of the leading edge is costly and is not for all applications and especially not suitable for solving printing problems on site. The term cylinder includes both cylinders in the classic sense, such as. B. Offset cylinders, but also blanket-related rollers, such as B. inking rollers understood.

Aufgabe der Erfindung ist die Schaffung eines Zylinders mit einfachen und auch vor Ort an­ wendbaren Mitteln zur Vermeidung von Kanalrückwirkung.The object of the invention is to create a cylinder with simple and also on site reversible means to avoid sewer reaction.

Die Aufgabe wird durch die Merkmale des Patentanspruches gelöst.The object is achieved by the features of the patent claim.

Nachfolgend wird die Erfindung an einem Ausführungsbeispiel näher beschrieben.The invention is described in more detail below using an exemplary embodiment.

In Fig. 1 ist eine Teilansicht eines Zylinders in perspektivischer Ansicht dargestellt. Dabei werden unter dem Begriff Zylinder neben Zylindern, wie gummituchbespannte Offsetzylinder auch gummituchbespannte Walzen verstanden. Der Zylinder 1 weist einen Zylinderkanal 2 auf und ist mit mindestens einer Druckfläche 3 ausgestattet. Der Übergang vom Zylinderkanal 2 zu der Druckfläche 3 ist kurvenförmig, eine Anlaufkante 4 bildend, ausgebildet. Der Zylinder 1 ist mit einem Gummituch 5 bespannt, wobei die Gummituchspannung nur schematisch dargestellt und mit dem Bezugszeichen 11 versehen ist (Fig. 2). Zwischen der Druckfläche 3 des Zylinders 1 und dem Gummituch 5 ist eine Folie 6 angeordnet. Die Folie ist kalibriert und in unterschiedlichen Dicken verwendbar. Damit ist es möglich die Aufzugs­ stärke zu variieren. In Fig. 1 is a partial view of a cylinder is shown in a perspective view. The term cylinder is understood to mean not only cylinders, such as blanket-covered offset cylinders, but also blanket-covered rollers. The cylinder 1 has a cylinder channel 2 and is equipped with at least one pressure surface 3 . The transition from the cylinder channel 2 to the pressure surface 3 is curved, forming a leading edge 4 . The cylinder 1 is covered with a rubber blanket 5 , the rubber blanket tension only being shown schematically and provided with the reference number 11 ( FIG. 2). A film 6 is arranged between the printing surface 3 of the cylinder 1 and the rubber blanket 5 . The film is calibrated and can be used in different thicknesses. This makes it possible to vary the strength of the elevator.

Die Folie 6 ist vorteilhafterweise selbstklebend ausgestattet. Die Folie 6 reicht von vor dem Anfang des zu druckenden Motivs 10 bis nach Ende des zu druckenden Motivs 10, wobei unter Motivanfang und Motivende Anfang und Ende der zu bedruckenden Fläche verstanden wird. Die in Achsrichtung 7 des Zylinders 1 angeordneten vorderen und hinteren Kanten 8; 9 der Folie 6 sind relativ zur Achsrichtung 7 schräg geschnitten, d. h. Achsrichtung 7 und Kanten 8; 9 schließen einen Winkel a größer Null ein. Die geometrischen Verhältnisse des Folienzuschnittes, der Motivgröße und der Zylinderkan­ ten sind in Fig. 3 dargestellt. The film 6 is advantageously self-adhesive. The film 6 extends from before the start of the motif 10 to be printed after the end of the motif 10 , the beginning and end of the surface to be printed being understood as the beginning and end of the motif. The front and rear edges 8 ; arranged in the axial direction 7 of the cylinder 1 ; 9 of the film 6 are cut obliquely relative to the axis direction 7 , ie axis direction 7 and edges 8 ; 9 enclose an angle a greater than zero. The geometric relationships of the film cut, the size of the motif and the cylinder edges are shown in FIG. 3.
