Description

Verfahren zur Herstellung von Sandbettungen zur Aufnahme elastischer Negative Die Erfindung betrifft ein Verfahren zum Herstellen von Sand!bettungen zur Aufnahme elastischer Negative, die über einem Originalmodell in Gipskappen ,geformt sind.Process for the production of sand beds for the absorption of elastic Negative The invention relates to a method for producing sand beds for holding elastic negatives, which are molded over an original model in plaster caps are.

Bisher sind die elastischen Negative während des Trocknens in .den zu ihrer Formung verwendeten Gipskappen verblieben, so daß die letzteren in größerer Anzahl vorhanden sein mußten oder zur Herstellung einer größeren Anzahl Negative zu große Wartezeiten nötig waren.So far, the elastic negatives are in .den while drying plaster caps used to shape them remained, so that the latter in larger Number had to be available or to produce a larger number of negatives too long waiting times were necessary.

Gemäß der Erfindung werden die in bekannter Weise mit Hilfe elastischer Negative hergestellten Gipskappen mit Gips ausgegossen, und mit dem so hergestellten Gipsmodell werden in Formkästen Bettungen aus Sand hergestellt, in denen die mittels des Originahnodells,in bekannter Weise hergestellten elastischen Negative zwecks Trocknung Aufnahme finden.According to the invention, they are made more elastic in a known manner Negative plaster of paris copings poured with plaster, and with the so produced Plaster models are made in molding boxes made of sand, in which the means of the original model, elastic negatives produced in a known manner for the purpose Find drying intake.

Auf diese Weise ist es möglich, jederzeit rasch eine beliebige Anzahl Ablegefortnei für die elastischen Negative herzustellen und die Formarbeit ,auf kürzeste Zeit zusammenzufassen. Außerdem können die Ablegeformen mittels des Gipsklotzes durch ungelernte billigere Kräfte hergestellt werden.In this way it is possible to quickly add any number at any time Establish filing for the elastic negatives and the form work summarize the shortest time. In addition, the placement forms can be made using the plaster block be produced by unskilled cheaper workers.
