Vorliegende Erfindung betrifft die Herstellung einer neuen Buchdruckwalzenmasse, welche neben einer gröfseren Haltbarkeit und Dauerhaftigkeit die Vortheile bietet, dafs sie nach mehrmaligem Umschmelzen noch brauchbar ist, zum Umschmelzen weniger Zeit erfordert und dabei dünnflüssiger wird.The present invention relates to the production of a new letterpress roller mass which besides a greater durability and durability, the advantages that it offers after repeated remelting is still usable, requires less time for remelting and becomes thinner.
Die im Handel befindliche sogenannte amerikanische Buchdruckwalzenmasse hat eine ähnliche Zusammensetzung; sie besteht aus Gelatine und Glycerin. Diese Masse hat aber den Uebelstand, dafs sie infolge eines als Binde- oder Füllmaterial benutzten Zusatzes nach dem Umschmelzen klümperig wird und daher verworfen werden mufs.The so-called American letterpress roller mass available on the market has a similar composition; it consists of gelatin and glycerine. But this mass has the disadvantage that it is the result of an additive used as a binding or filling material becomes lumpy after remelting and must therefore be discarded.
Die Herstellung der neuen Buchdruckwalzenmasse geschieht in der Weise, dafs man Gelatine, Glycerin, Borax, Knochenfett und Stearinöl in geeignetem Verhältnifs zusammenschmilzt und in passenden Formen erkalten läfst.The production of the new letterpress roller mass is carried out in such a way that one Gelatin, glycerin, borax, bone fat and stearic oil melt together in suitable proportions and let it cool down in suitable forms.
Die neue Masse hat die vorteilhaften Eigenschaften, beim Gebrauch wenig zu schwinden und nach dem Umschmelzen, nachdem man sie einige Tage an der Luft der Ruhe überlassen hat, wieder ihre ursprüngliche Festigkeit und glatte Oberfläche anzunehmen.The new mass has the advantageous properties of not shrinking much during use and after remelting, after leaving them in the open air for a few days has to regain its original strength and smooth surface.
Die Eigenschaft, leichter zu schmelzen und dabei dünnflüssiger zu werden, verdankt die Masse dem Zusätze von Rinderknochenfett und Stearinöl und unterscheidet sich dadurch wesentlich von den bekannten W'alzenmassen, die zwar auch zum Theil Fett enthalten, jedoch keinen Stearinölzusatz aufweisen.It owes its ability to melt more easily and become thinner in the process Mass the additives of beef bone fat and stearic oil and differs in this substantially different from the known rolling masses, some of which also contain fat, however do not contain any added stearic oil.
Für die in der Accidenzdruckerei gebräuchlichen Walzen hat sich folgendes Mischungsverhältnifs der Masse als zweckmäfsig erwiesen:The following mixing ratio has been used for the rollers commonly used in commercial printing proved to be appropriate for the mass:
60 Gewichtstheile Gelatine,60 parts by weight of gelatin,
80 „ Glycerin,80 "glycerine,
1,4 „ Borax,1.4 "borax,
1,4 ,, Stearinöl,1,4 ,, stearic oil,
0,7 ,, Rinderknochenfett.0.7 ,, beef bone fat.
Für die Walzen von Rotationsdruckmaschinen kommt eine Masse von folgender Zusammensetzung in Anwendung:A mass of the following composition is used for the rollers of rotary printing machines in use:
50 Gewichtstheile Glycerin, 50 ,, Gelatine,50 parts by weight of glycerine, 50, gelatin,
1,0 „ Borax,1.0 "borax,
Stearinöl,Stearic oil,
Rinderknochenfett.Beef bone fat.
Die Gelatine wird vor der Verwendung mit 15 pCt. ihres Gewichtes Wasser angerührt.The gelatin is mixed with 15 pCt. touched their weight of water.
Die obigen Gewichtsverhältnisse erfahren je nach der der Jahreszeit entsprechenden Temperatur eine geringe Schwankung, welche nur erfahrungsgemäfs festgestellt wird.The above weight ratios depend on the temperature corresponding to the season a slight fluctuation, which is only determined by experience.
