Description

Verfahren zur Herstellung von Matrizen für Gummidruckformen. Zwecks Herstellung von Matrizen für zu vulkanisierende Gummidruckformen, Stempel tt. d-gl. bedient man sich bisher fast ausschließlich einer gipsartigen, aus verschiedenen Motten (Gips, Kaolin, Dextrin) zusammengesetzten Masse, die, mit `Wasser angesetzt, bald erhärtet und dann- noch vorsichtig getrocknet «-erden muß. Neuerdings hat man auch versucht, zum Abformen der" Originale für genannten Zweck Trockenrnatern aus Pappe sowie gewöhnliche Papiermatern zu benutzen, wie sie allgemein in der Stereotypie Verwendung finden. Die erstgenannte Masse hat den Nachteil, daß die Herstellung der Matrize zuviel Zeit in Anspruch nimmt und sie meist nur einmal benutzt Zierden kanj, außerdem aber sich beim Trocknen leicht Sprünge und Risse bilden, die die Matrize unbrauchbar machen. Pappmatrizen sind zwar schneller herzustellen, sie geben aber keinen reinen Abdruck, weil sich beim Vulkanisierungsprozeß leicht Fasern der Pappe ablösen und am Gummi haften bleiben.Process for the production of matrices for rubber printing forms. For the purpose of Production of matrices for rubber printing forms to be vulcanized, stamps tt. d-gl. So far, one has almost exclusively used a plaster of paris, from different ones Moths (plaster of paris, kaolin, dextrin) are a compound that, when mixed with `water, soon hardened and then - carefully dried "- must earth. Recently one has also tried to mold the "originals for the mentioned purpose" drying out To use cardboard as well as ordinary paper materials, as they are commonly used in stereotype Find use. The former mass has the disadvantage that the production the die takes too much time and usually only uses it once kanj, but also cracks and cracks easily form when drying, which the Make the die unusable. Cardboard matrices are quicker to manufacture, they give but not a pure impression, because fibers of the Remove the cardboard and stick to the rubber.

Die Erfindung besteht in der Verwendung einer aus Weichblei bestehenden Matrize, die durch einfache Prägung hergestellt ist. Diese Matrize gibt nicht nur einen allen Zwecken entsprechenden geeignefeti scharfen und auf der Oberfläche der Druckelemente blanken Abdruck, sondern hält auch eine beliebige Anzahl von Vulkanisierungen aus.The invention consists in the use of one made of soft lead Die that is made by simple embossing. This die is not only a suitable sharp and suitable for all purposes Surface of the printing elements bare imprint, but also holds any number from vulcanization.

Die Widerstandsfähigkeit dieser Matrize kann noch erhöht werden, wenn ihre Rückseite in den Bunzen und Blankstellen durch Gips oder einen anderen entsprechenden; unnachgiebigen Füllstoff ausgefüllt wird.The resistance of this die can be increased if their back in the bunches and bare spots by plaster of paris or another equivalent; unyielding filler is filled.

Benutzt man zum Abprägen der Form Weichbleiplatten,welche auf ihrer Rückseite geriffelt sind, dann kann die Prägung bei geringerem Druck erfolgen.If you use soft lead plates to stamp the shape, which are on their The reverse side are corrugated, then the embossing can be done with less pressure.

Die. Zeichnung erläutert ein Ausführungsbeispil einer nach :dem neuen Verfahren erzeugten Matrize, wobei veranschaulichen Abb, i den Abschnitt einer Weichbleiplatte a mit Riffelung a', Abb. 2 und g einen Teil dieser Platte in Rückansicht und im Querschnitt, stark vergrößert, aus welchen Darstellungen ersichtlich ist, daß zufolge der auf der Rückseite der Platte vorgesehenen Riffelung neben- und übeneinanderliegende Ansätze in Form abgestumpfter Pyramiden a2 entstellen.The. Drawing explains an exemplary embodiment one after: the new one Method generated die, fig, i illustrating the section of a soft lead plate a with corrugation a ', Fig. 2 and g a part of this plate in rear view and in Cross-section, greatly enlarged, from which representations it can be seen that according to the corrugation provided on the back of the plate next to and on top of one another Disfigure approaches in the form of truncated pyramids a2.
