Description

Verfahren zum Herstellen von Flachdruckformen für Buch- und Zeitungsdruck durch Umdruck eines mit der Schreibmaschine hergestellten Schriftsatzes In Patent 639 93,1 ist ein Verfahren beschrieben, Flachdruckformen für Buch- und Zeitungsdruck dadurch herzustellen, daß mit der Schreibmaschine ein Schriftsatz auf mit Kautschuk o. dgl. überzogene Teilwalzen gedruckt und von diesen auf anderweitig mit Zeitungskopf, Linien usw. versehene Flachdruckplatten in genauer Anschlußfolge umgedruckt wird.Process for the production of planographic printing forms for letterpress and newspaper printing by transferring a typeface made with a typewriter. In Patent 639 93.1 describes a process for flat printing forms for letterpress and newspaper printing to produce that with the typewriter a brief on with rubber o. the like. Coated partial rollers printed and from these on otherwise with newspaper head, Lines, etc. provided planographic printing plates is transferred in an exact connection sequence.

Da es Schreibmaschinen oder sogenannte Schriftmaschinen (Schreibmaschinen für Buchdruck) gibt, die nicht so eingerichtet sind, daß sie unmittelbar auf die Oberfläche von Teilwalzen drucken können, und welche z. B. in der Weise von einer durch Drehung und Längsverschiebung einstellbaren Typenwalze drucken, daß eine flach eingespannte Druckfolie von hinten durch einen kleinen Stempel gegen die jeweils eingestellte Drucktype gepreßt wird, so bedarf es einer Vorrichtung, um den Kautschuküberzug der Teilwalze zum Zwecke des Bedruckens in der Schreibmaschine abzunehmen und nach erfolgtem Bedrücken wieder auf die Teilwalze aufzuspannen. Dabei ist es, um beim Umdruck der Teilwalze auf die Flachdruckplatte eine genaue Anschlußfolge des Drucksatzes zu erzielen, unerläßlich, daß der Kautschuküberzug sowohl beim Bedrucken in der Schreibmaschine als auch beim Umdrucken von der Teilwalze auf die Flachdruckplatte sich genau an :einer bestimmten Stelle befindet. Dies wird erfindungsgemäß dadurch erreicht, daß der Kautschuküberzug eine nicht dehnbare Unterlage erhält, die in einer bestimmten Weise so auf- bzw. eingespannt werden kann, daß sie sowohl in der -Schreibmaschine als auch auf der Teilwalze immer die gleiche Lage einnimmt.Since there are typewriters or so-called typewriters (typewriters for letterpress printing) that are not set up in such a way that they directly access the Can print surface of partial rollers, and which z. B. in the manner of a by rotation and longitudinal displacement adjustable type roller print that one flat clamped printing film from behind by a small stamp against each If the set pressure type is pressed, a device is required to cover the rubber remove the part roller for the purpose of printing in the typewriter and after clamped again on the partial roller after pressing. It is in order to Transfer printing of the partial roller onto the planographic printing plate an exact connection sequence of the printing set To achieve, it is essential that the rubber coating is used both during printing Typewriter as well as transfer printing from the partial roller onto the planographic printing plate is exactly at: a certain point. According to the invention, this is thereby achieved achieves that the rubber cover receives a non-stretchable base, which in a certain way so on or can be clamped that they are both in the - Typewriter and on the part roller always occupies the same position.

Zu diesem Zwecke dient beispielsweise die in der Abbildung (Querschnitt der Teilwalze) dargestellte Spannvorrichtung.For this purpose, for example, the one in the figure (cross-section the partial roller) shown clamping device.

i ist der Körper der Teilwalze. 2 ist der Überzug. 3 ist der vordere, zweckmäßig durch eine Einlage oder Schiene verstärkte Rand des hberzuges. 4 ist der hintere, ebenso verstärkte Rand desselben. 5 sind hakenförmige Stifte, hinter die der Rand 3 faßt, der mit länglichen Löchern 6 versehen ist. Am Rande 4 sind Schrauben 7 befestigt, deren Muttern 8 angezogen werden, nachdem 'die Schrauben in entsprechende Aussparungen einer an der Teilwalze befestigten Leiste 9 gelegt sind. Hierdurch wird der tiberzug 2 gespannt, und zwar jedesmal an derselben Stelle der Teilwalze, weil die Stifte 5 in Verbindung mit den Löchern 6 und die Schrauben 7 in Verbindung mit den Aussparungen der Leiste g eine andere Lage des überzuges nicht zulassen. Es muß dabei verhindert werden, daß sich der Überzug in der Richtung des Walzenumfanges beim Spannen reckt. Dies wird dadurch erreicht, daß der L berzug 2 aus einer gummiartigen äußeren Haut und einer nicht dehnbaren Unterlage zusammengesetzt wird. Hierfür eignet sich z. B. ein Metallblech, das dünn und elastisch genug ist, um in der Schriftmaschine als Folie zu dienen; auch ein nicht dehnbares Gewebe kann benutzt werden.i is the body of the partial roller. 2 is the coating. 3 is the front one, the edge of the cover is suitably reinforced with an insert or rail. 4 is the rear, equally reinforced edge of the same. 5 are hook-shaped pins, behind which the edge 3 grips, which is provided with elongated holes 6. There are 4 on the edge Screws 7 fastened, the nuts 8 of which are tightened after 'the screws placed in corresponding recesses of a bar 9 attached to the partial roller are. As a result, the coating 2 is tensioned, each time at the same point the part roller because the pins 5 in connection with the holes 6 and the screws 7 in connection with the recesses in the bar g another layer of the coating not allow. It must be prevented that the coating is in the direction the roller circumference stretches during tensioning. This is achieved in that the L coating 2 composed of a rubber-like outer skin and a non-stretchable pad will. For this, z. B. a sheet of metal that is thin and elastic enough to serve as a foil in the typewriter; even a non-stretchable fabric can to be used.

Die Vorrichtung zum Spannen des überzuges kann auch mit anderen bekannten Mitteln ausgebildet sein. Die angegebene Form ist nur ein Beispiel.The device for tensioning the coating can also be used with other known ones Means be formed. The form given is just an example.
