Description

Die Erfindung hat eine Weichwalze mit Gummiüberzug für Prägekalander, insbesondere zum Prägen von Leder und Kunststoff, sowie ein Verfahren zur Herstellung dieser Walze zum Gegenstand mit dem Ziel, eine Weichwalze mit Gummiüberzug zu schaffen, bei welcher der Gummiüberzug nicht nur zur elastischen Wirkung kommt, sondern auch eine hinreichend lange Lebensdauer hat. The invention has a soft roll with rubber coating for embossing calenders, in particular for embossing leather and plastic, as well as a method for production this roller to the object with the aim of creating a soft roller with a rubber cover, in which the rubber cover not only has an elastic effect, but also has a sufficiently long service life.

Walzen für Prägekalander mit Gummiüberzug sind bereits bekannt; In der Regel sind diese Walzen so ausgebildet, daß der stählerne Walzenkern mit einer Hülle aus Weichgummi versehen und über diese Hülle eine die Arbeitsoberfläche der Walze ergebende Hülle aus Hartgummi angeordnet ist. Rolls for embossing calenders with a rubber coating are already known; In As a rule, these rollers are designed so that the steel roller core with a Cover made of soft rubber provided and over this cover the work surface of the Roller resulting shell made of hard rubber is arranged.

Da bekanntlich die Nachgiebigkeit von Gummi auf der Fließfähigkeit des Gummis beruht und der Gummi bei der bekannten Walzenausbildung in radialer Richtung nach der Walzenmitte zu keine Ausweichmöglichkeit hat, tritt beim Gebrauch der Walzen ein Walken des Gummis ein, d. h. an der Anliegestelle der Hartwalze wird der Gummi eingedrückt, um zu beiden Seiten der Anliegestelle hochzuquellen. Dies führt zu einer Erwärmung und baldigen Zerstörung des Gummis.As is well known, the flexibility of rubber on the flowability of the rubber is based and the rubber in the known roller design in the radial direction after the roller center has no alternative, occurs when the rollers are used a fulling of the rubber, d. H. the rubber becomes at the contact point of the hard roll pressed in to swell up on both sides of the landing stage. this leads to a heating and early destruction of the rubber.

Nach der Erfindung ist zwischen dem Walzenkern und dem Gummiüberzug ein aufzupumpender Schlauchwickel vorgesehen. Hierdurch kann die Nachgiebigkeit des Gummis ohne nachteilige Erscheinungen voll zur Wirkung kommen; denn infolge der Zusammenpreßbarkeit des in dem Schlauchwickel befindlichen Luftpolsters hat der Gummi eine Ausweichmöglichkeit, welche keine Oberflächenverformung im Sinne eines Walkens bedingt. According to the invention is between the roller core and the rubber cover a hose reel to be inflated is provided. This can reduce the flexibility of the rubber come into full effect without adverse effects; because as a result the compressibility of the air cushion located in the hose roll the rubber an alternative, which no surface deformation in the sense due to a walk.

Die Herstellung der Walze kann erfindungsgemäß in der Weise vorgenommen werden, daß der Schlauchwickel luftleer gemacht, der Gummiüberzug über den luftleeren Wickel geschoben und hiernach der Wickel aufgepumpt wird. According to the invention, the roller can be produced in this way that the hose coil is evacuated, the rubber cover over the evacuated The lap is pushed and then the lap is inflated.

Die Zeichnung veranschaulicht ein Ausführungsbeispiel der erfindungsgemäßen Walze in schematischer Darstellung. The drawing illustrates an embodiment of the invention Roller in a schematic representation.

Abb. I gibt einen Längsschnitt durch die Walze wieder; Abb. 2 zeigt eine Stirnansicht. Fig. I shows a longitudinal section through the roller; Fig. 2 shows a front view.

Der stählerne Walzenkern ist mit 1 bezeichnet. The steel roller core is denoted by 1.

Auf ihm ist der Schlauchwickel 2 angeordnet, dessen Schlauchquerschnitt bei dem Ausführungsbeispiel rund ist, aber auch jede andere geeignete Form, so die Form eines Rechtecks, haben kann.The hose reel 2 is arranged on it, its hose cross-section is round in the embodiment, but also any other suitable shape, so the Shape of a rectangle.

Der Schlauchwickel bildet eine dicht gewundene Spirale. Um den Schlauchwickel ist der Überzug oder die Hülle 3 aus Gummi gelegt. Der Schlauchwickel ist mit Luft aufgepumpt, so daß der Überzug einen festen Sitz hat. Die Seitenschilder 4 sichern die Lage des Schlauchwickels auf dem Walzenkern.The hose coil forms a tightly wound spiral. Around the hose wrap the cover or the sheath 3 is made of rubber. The hose wrap is with air inflated so that the cover has a tight fit. Secure the side plates 4 the position of the hose roll on the roller core.

Die Enden des Schlauchwickels können am Walzenkern festgelegt und mit durch die Seitenschilder geführtem Anschlußstutzen versehen sein.The ends of the hose roll can be set on the roller core and be provided with connecting pieces passed through the side plates.
