Bei der bekannten Herstellung von Walzenmasse für Druckereiauftragwalzen aus Leim, Gelatine, Glucose und Glycerin zeigt sich der Uebelstand, dafs das Product einen Ueberschufs an Feuchtigkeit enthält. Es entsteht daher kein vollkommen gleichmäfsiges, elastisches, gegen Temperatureinflüsse und Staub unempfindliches, nicht einschrumpfendes Walzenmaterial, wie solches erforderlich ist, um einen klaren, gleichmäfsigen Abdruck zu erzielen.In the known production of roller mass for printing application rollers from glue, Gelatin, glucose, and glycerine show the disadvantage that the product is in excess contains moisture. There is therefore no perfectly uniform, elastic, non-shrinking roller material that is insensitive to temperature influences and dust, how such is necessary to obtain a clear, even impression.

Man versuchte diesen Uebelstand dadurch zu beseitigen, dafs bei Herstellung von Walzenmasse nur so viel bezw. nur so wenig Wasser in Anwendung gebracht wurde, wie gerade zur Auflösung des Leimes und der Gelatine unbedingt nothwendig war; aber auch hiermit wurde kein vollkommen gleichmäfsiges Product erzielt.Attempts were made to remedy this disadvantage by making roller mass only so much respectively. only as little water was used as was used to dissolve the glue and gelatin was absolutely necessary; but this also did not result in a perfectly uniform product achieved.

Die vorliegende Erfindung beseitigt diesen Nachtheil dadurch, dafs zu der aus Gelatine, Leim, Glucose und Glycerin zusammengesetzten Masse, nachdem der Leim und die Gelatine in kaltem Wasser gelöst wurden, ein Zusatz von Methylalkohol oder mit Holzgeist versetztem Spiritus gegeben wird, zum Zwecke, den schädlichen Ueberschufs an Wasser zu beseitigen.The present invention overcomes this disadvantage in that, in addition to that of gelatin, Glue, glucose and glycerin compound mass after the glue and the gelatin dissolved in cold water, an addition of methyl alcohol or wood spirit Spirit is given for the purpose of eliminating the harmful excess of water.

Dieses geschieht dadurch, dafs der Zusatz an Methylalkohol oder von mit Holzgeist versetztem Spiritus bei seiner theilweisen Verdunstung den Ueberschufs an Wasser entfernt.This is done by adding methyl alcohol or wood spirit Spirit, with its partial evaporation, removes the excess of water.

Die mit Methylalkohol hergestellte Walzenmasse besitzt nicht die eingangs erwähnten Nachtheile und zeichnet sich noch dadurch aus, dafs sie beliebig oft umgegossen werden kann, ohne ihre Elasticität und Geschmeidigkeit zu verlieren und ohne einzuschrumpfen.The roller mass produced with methyl alcohol does not have that mentioned at the beginning Disadvantages and is also distinguished by the fact that they are poured over as often as desired can without losing its elasticity and suppleness and without shrinking.
