Description
Vorrichtung zum Befestigen kurzer Kupfermäntel auf den Formzylindern von Rotationstiefdruckmaschinen Die Erfindung betrifft eine Vorrichtung, durch die es ermöglicht wird, a=uf den Formzylindern vom Roitats:onstiefdruck Faschinen Kupfermäntel zu befestigen, die kürzer als der Formzylinder sind.Device for attaching short copper jackets to the forme cylinders of rotogravure printing presses The invention relates to a device through which it is made possible on the forme cylinders of the Roitats: on gravure fascines copper jackets to be attached that are shorter than the forme cylinder.
Der kurze, über den Formzylinder gezogene Kupfermantel wird gegen Verdrehung durch einen Keil gesichert, der einers=eits in eine Nut des Formzylinders und anderseits in eine Gegennut des Kupfermantels greift.The short copper jacket drawn over the forme cylinder is counteracted Rotation is secured by a wedge, which is on the one hand in a groove in the forme cylinder and on the other hand engages in a counter groove in the copper jacket.
Um nun dem Kupfermantel auf dem Form. zylinder auch einen seitlichen Halt zu geben, wird gemäß der Erfindung auf den mantelfreien T«a des Formzylinders eine SpannhüUse gezogen, deren Außendurchmesser kleiner ist als der des Kupfermantels und so von der Farbwalze nicht berührt wird. Dier Kupfermantel und die Spa.nnhiilsse werden beiderseits in an sich bekannter WeW durch die in Gewinden nach der Mitte zu geführten Spannringe auf dem Fonnzylluder festgehalten und gegeneinander gespannt.To now the copper jacket on the form. cylinder also a side According to the invention, support is provided on the jacket-free T «a of the forme cylinder A clamping sleeve is drawn, the outside diameter of which is smaller than that of the copper jacket and so is not touched by the inking roller. The copper sheath and the spa fittings are on both sides in a known WeW through the threads towards the middle held to guided clamping rings on the Fonnzylluder and clamped against each other.
Auf der Zeichnung ist die Erfindung beispielsweise veranschaulicht, rund zwar stellein dar: Abb. i einen Formzylinder mit einem etwa halb so langen Kupfermantel, Abb. 2 und 3 andere Längen von Kupfermänteln und Abb. q. .einen Foirmzylinder in Querschnitt. über den Formzylinder a ist der mit den Ätzungen versehene, die halbe Zylinderlänge deckende Kupfermantel b gezogen und dort durch einen Keil. c ,gegen Verdrehung festgehalten (Abb. q.).The invention is illustrated in the drawing, for example, round represents: Fig. i a forme cylinder with a half as long Copper jacket, Fig. 2 and 3 other lengths of copper jacket and Fig. Q. .a foil cylinder in cross section. over the forme cylinder a is the one provided with the etchings, the half the cylinder length covering copper jacket b pulled and there through a wedge. c , held against rotation (Fig. q.).
Der Keil c greift einerseits in die Nut d des Fo.rmzvlinders und anderseits in die Gegennute des Kupfermantels b.The wedge c engages on the one hand in the groove d of the Fo.rmzvlinder and on the other hand into the opposite groove of the copper jacket b.
Um dem Kupfermantel b auf dem Druckzylindera auch einen seitlichen Halt zu geben, wird noch eine Spannhülssel auf den Formzy#Iindera gezogen, di=e im Außendurchmesser kleiner als der Kupfermantel ist und so von der Farbwalze nacht berührt wird. Der Kupfermantel b und die Spannhälse i werden beiderseits in an sich bekannter Weise durch die in Gewinden nach der 1Vütte zu geführten Spannringe g und h auf den Formzylinder festgehalten und gegeneinander gespannt.Around the copper jacket b on the printing cylinder a also a lateral one To give hold, a clamping sleeve is pulled onto the Formzy # Iindera, di = e is smaller in the outer diameter than the copper jacket and is thus affected by the inking roller is touched. The copper jacket b and the clamping necks i are on both sides in per se in a known manner by the clamping rings g to be guided in threads after the 1Vütte and h held on the forme cylinder and clamped against each other.
Selbstverständlich gehören zu .den Kupfermänteln vers-chmedener Länge auch verschieden lange 'Spannhülsen f, wie solche in den Abb. z und 3 mit gestrIchelten Linien angedeutet sind.Of course, different lengths belong to the copper sheaths also different lengths of clamping sleeves f, like those in Figs. z and 3 with dashed lines Lines are indicated.
