Description

Verfahren zur Herstellung von Gegenständen aus Celluloid oder ähnlichen plastischen lassen Bei der Herstellung von Gegenständen aus Celluloid oder ähnlichen plastischen Massen ist vielfach die Anwendung von Druck notwendig, um entweder die Masse in bestimmte Formen zu bringen, verschiedene Teile zu vereinigen oder auch Verzierungen, wie Aufdrucke o. dgl., anzubringen.Process for the production of articles from celluloid or the like plastic leave in the manufacture of objects from celluloid or similar plastic masses, the application of pressure is often necessary to either the To bring mass into certain forms, to unite different parts or else Ornaments, such as prints or the like. To be attached.

Bisher hat man nun beispielsweise bei der Vereinigung von Celluloidplatten, -blättern o. dgl. oder bei der Anbringung von Verzierungen, wie Drucke usw., bereits trockene Massen verwendet und die Vereinigung oder den Aufdruck unter Anwendung eines Lösungsmittels bewirkt. Ursache hierfür war der Umstand, daß noch feuchte Celluloidmasse beim Pressen auch an dem Preßteil anhaftet und von diesem nur schwer und jedenfalls nicht ohne Beschädigung getrennt werden kann.So far, for example, when combining celluloid plates, -leave o. The like. Or when attaching decorations, such as prints, etc., already used dry masses and applying the union or imprint a solvent causes. The reason for this was the fact that it was still damp Celluloid mass also adheres to the pressed part during pressing and only with difficulty from this and in any case cannot be separated without damage.

Gemäß der Erfindung wird nun die Vereinigung der Schichten, auch bei noch feuchtem Zustande der Masse dadurch ermöglicht, daß zwischen dem Preßorgan und der Masse eine mit einer lösbaren Schicht, etwa Gummi, Gelatine o. dgl., versehene Zwischenschicht, vorzugsweise aus Papier, angebracht wird. Die lösbare Schicht kommt dabei auf die plastische Masse zu liegen. Das Preßorgan kommt nun nicht unmittelbar mit der plastischen Masse in Berührung, so daß ein Anhaften vermieden wird.According to the invention, the union of the layers is now, also with the still moist state of the mass is made possible by the fact that between the pressing member and the mass is provided with a removable layer such as gum, gelatin or the like Intermediate layer, preferably made of paper, is attached. The releasable layer comes while lying on the plastic mass. The pressing organ does not come immediately with the plastic mass in contact, so that sticking is avoided.

Um beispielsweise zwei oder mehrere Celluloidplatten zu vereinigen, werden diese in noch feuchtem Zustande aufeinandergelegt. auf die äußerste Schicht dann je ein gummiertes Papierblatt mit der gummierten Seite aufgelegt und das Ganze dann in eine Presse o. dgl. gebracht. Nach der Pressung und Vereinigung der Teile wird das Papier mit Wasser abgeweicht und der etwa noch anhaftende Gummi abgewaschen.For example, to unite two or more celluloid plates, these are placed on top of one another while they are still moist. on the outermost layer then put a sheet of gummed paper with the gummed side and the whole thing then brought into a press or the like. After pressing and joining the parts the paper is soaked with water and any remaining gum is washed off.

Das Verfahren ermöglicht also die beliebige Behandlung noch fabrikationsfeuchter plastischer Massen, macht also die bisher notwendige Anwendung von Lösungs- oder Bindemitteln unnötig und gewährleistet eine derartig gleichmäßig einwandfreie Bindung, wie sie sonst nicht zu erreichen ist. Die Behandlung wird wesentlich vereinfacht und verbilligt.The process thus enables any treatment to be carried out while still moist from the factory plastic masses, so makes the previously necessary application of solution or Binders unnecessary and ensures such a uniformly flawless bond, as it is otherwise not to be reached. The treatment is simplified considerably and cheaper.

Man kann bei Anwendung des vorliegenden Verfahrens mit der plastischen noch feuchten Masse gegebenenfalls auch trockene plastische Massen verbinden, wobei das in der feuchten Masse enthaltene Lösungsmittel die Verbindung bewirkt. Ein besonderes Lösungsmittel ist auch in diesem Falle entbehrlich.You can use the present method with the plastic Connect still moist mass, if necessary, also dry plastic masses, whereby the solvent contained in the wet mass causes the connection. A special Solvent is also unnecessary in this case.
