Definitions

  • the invention relates to a cylinder of a rotary printing press, in particular a transfer cylinder, with a jacket made of rigid material, the jacket surface of which has a low coefficient of friction and which is covered with a net.
  • the known cylinder consists of an aluminum jacket, the jacket surface of which is coated with fluoropolymer.
  • the desired low coefficient of friction of the lateral surface is thereby achieved, so that displacements between the net and the actual cylinder can result.
  • This known cylinder is relatively expensive to manufacture, in particular due to the necessary coating of the aluminum sheet with the plastic.
  • the invention is therefore based on the object of proposing a cylinder having the features mentioned at the outset, which, while maintaining the advantages of the cylinder, in particular a low coefficient of friction of the cylinder jacket surface and coating of the cylinder with the network, is distinguished by noticeably reduced production costs.
  • the jacket consists of a stainless steel sheet.
  • the invention is explained in more detail below on the basis of an exemplary embodiment from which further important features result.
  • the figure shows schematically a section of a development of the jacket of a cylinder according to the invention.
  • this consists of a stainless steel sheet 1 of suitable thickness (V2A steel), which is coated on the outside with a mesh-like fabric 2, as is essentially described in the European Laid-Open Specification 59,944 mentioned at the outset.

Description

  • Die Erfindung betrifft einen Zylinder einer Rotations-Druckmaschine, insbesondere einen Transferzylinder, mit einem Mantel aus starrem Material, dessen Mantelfläche einen niedrigen Reibungswert hat, und der mit einem Netz überzogen ist.
  • Ein derartiger Zylinder ist in der europäischen Offenlegungsschrift 59 944 beschrieben. Er hat sich an und für sich bewährt, insbesondere wegen des Überzugs aus einem netzartigen Gewebe, wodurch der Kontakt zwischen dem Zylinder und den von den Zylindern zu fördernden Bögen verbessert wird.
  • Der bekannte Zylinder besteht aus einem Aluminiummantel, dessen Mantelfläche mit Fluorpolymer beschichtet ist. Dadurch wird der gewünschte niedrige Reibungswert der Mantelfläche erreicht, so daß sich Verschiebungen zwischen dem Netz und dem eigentlichen Zylinder ergeben können.
  • Dieser bekannte Zylinder ist in seiner Herstellung aber verhältnismäßig teuer, insbesondere bedingt durch die notwendige Beschichtung des Aluminiumblechs mit dem Kunststoff.
  • Der Erfindung liegt daher die Aufgabe zugrunde,einen Zylinder mit den eingangs genannten Merkmalen vorzuschlagen, der bei Beibehaltung der Vorteile des Zylinders, insbesondere niedriger Reibungswert der Zylinder-Mantelfläche und Überzug des Zylinders mit dem Netz, sich durch fühlbar verringerte Herstellungskosten auszeichnet.
  • Die Lösung dieser Aufgabe gelingt dadurch, daß der Mantel aus einem Edelstahlblech besteht.
  • Man erspart sich somit die aufwendige Herstellung des Zylindermantels aus einem mit einem entsprechend dünnen Material beschichteten Aluminiumblech und verwendet statt dessen ein Edelstahlblech, welches sowohl die notwendige Steifigkeit hat, wie auch den benötigten niedrigen Reibungswert.
  • Die Erfindung wird im folgenden anhand eines Ausführungsbeispiels näher erläutert, aus dem sich weitere wichtige Merkmale ergeben. Die Figur zeigt schematisch einen Ausschnitt aus einer Abwicklung des Mantels eines erfindungsgemäßen Zylinders.
  • Dieser besteht erfindungsgemäß aus einem Edelstahlblech 1 geigneter Stärke (V2A-Stahl), das außen mit einem netzartigen Gewebe 2 überzogen ist, wie es im wesentlichen in der eingangs erwähnten europäischen Offenlegungsschrift 59 944 beschrieben ist.
