Description
Bei den ersten Anfangen für Kupfertiefdruck wurden als Formzylinder Kupferrohre verwendet, die auf starke Graugußzylinder mit Stahlachsen aufgepreßt wurden. Heute werden diese Graugußzylinder gewöhnlich galvanisch mit einem Kupfermantel versehen, der immer wieder im Kupferbade aufgekupfert wird, wenn ein Anzahl Ätzungen abgeschliffen ist. Kupfermantel und Graugußzylinder bilden somit ein unzertrennliches Ganzes. Derartige Formzylinder sind hauptsächlich zum Druck von der Rolle in Verwendung. Für Bogendruckmaschiinen' ging man dazu über, Stahlrohre von ungefähr 5 mm Wandung zu verkupfern und diese auf einen in der Druckmaschine einseitig fest gelagerten Tragzylinder zu spannen, der als Expansionszylinder ausgebildet ist. Auch ist es bekannt, den Tragzylinder konisch auszubilden und auf diesen den den Kupferüberzug tragenden Hohlzylinder aufzuschieben.With the first beginnings of copper gravure printing, copper tubes were used as forme cylinders, which were pressed onto strong gray cast iron cylinders with steel axles. Today these gray cast iron cylinders are usually galvanically provided with a copper jacket, which is repeatedly coppered in the copper bath when a number of etchings have been ground off. The copper jacket and cast iron cylinder thus form an inseparable whole. Such forme cylinders are mainly used for printing from the roll. For Bogendruckmaschiinen 'one went over to copper steel tubes of about 5 mm wall and to clamp it to a cantilever mounted in the printing machine support cylinder which is formed as an expansion cylinder. It is also known to design the support cylinder conically and to push the hollow cylinder carrying the copper coating onto it.
Diese Stahlrohrzylinder haben den vollwandigen Zylindern gegenüber den Vorteil, daß sie leicht handlich und von einem Manne tragbar und einspannbar sind. Dagegen haben diese Zylinder den Nachteil, daß sie selten genau rund sind und daß selbst ein auf dem Expansionszylinder oder dem konischen Tragzylinder sehr fest aufgespannter Stahlrohrzylinder nicht überall auf dem Tragzylinder fest aufliegt. Es kommt außerdem nicht selten vor, daß sich ein solcher Zylinder beim Druck verschiebt, wodurch oft großer Schaden entsteht.These tubular steel cylinders have the advantage over the full-walled cylinders that they are easy to handle and can be carried and clamped by one man. Have against it these cylinders have the disadvantage that they are seldom exactly round and that even one on the Expansion cylinder or the conical support cylinder very tightly clamped tubular steel cylinder does not lie firmly on the support cylinder everywhere. It is also not uncommon for such a cylinder to be at the Pressure shifts, which often causes great damage.
Die Erfindung bezieht sich auf einen Tiefdruck-Formzylinder, der die Vorteile des leichten Stahlrohrzylinders hat, dagegen viel widerstandsfähiger ist als dieser und auf seinem Tragzylinder unbedingt genau aufliegt und sicher festsitzt.The invention relates to a gravure forme cylinder, which the advantages of light tubular steel cylinder, but is much more resistant than this and on its support cylinder is absolutely exactly and securely in place.
In der Zeichnung ist der Erfindungsgegenstand in einer beispielsweisen Ausführungsrorm veranschaulicht.In the drawing, the subject matter of the invention is shown in an exemplary embodiment illustrated.
Auf dem konischen Tragzylinder ι sitzt ein Rippenmantel 2 mit dem Kupferüberzug 3. Der Rippenmantel 2 hat eine dem konischen Tragzylinder 1 entsprechende konische Bohrung. Eine Scheibe 4 mit den Schrauben 5 dient zum Aufpressen des Mantels 2 auf den Tragzylinder 1. Nasen 6 der Scheibe 4 dienen dazu, den Rippenmantel 2 beim Aufstecken auf den Tragzylinder 1 konzentrisch zu führen. Die Nasen 6 passen in Aussparungen 7 des Tragzylinders 1, damit die äußerste Rippe des Rippenmantels 2 ihre Auflage nicht, verliert. Eine Scheibe 8 und Mutter 9 dienen dazu, den Rippenmantel 2 wieder vom Tragzylinder ι abzudrücken.A rib jacket 2 with the copper coating 3 is seated on the conical support cylinder ι. The rib jacket 2 has a conical bore corresponding to the conical support cylinder 1. A disk 4 with the screws 5 is used to press the jacket 2 onto the support cylinder 1. Lugs 6 of the disk 4 are used to guide the rib jacket 2 concentrically when it is slipped onto the supporting cylinder 1. The lugs 6 fit into recesses 7 of the support cylinder 1, so that the outermost rib of the rib jacket 2 does not lose its support. A washer 8 and nut 9 are used to push the rib shell 2 back from the support cylinder ι.
