Verfahren zur Herstellung von Projektionsflächen.
Vorliegende Erfindung bezieht sich auf ein Verfahren zur Herstellung von Projektionsflächen für die Vorführung kinematographischer Bilder und besteht darin dass man Guttaperchahaut zunächst in Benzin oder einem anderen Guttapt-t±La für die vereinigung mit Metallpulver geeignet machenden Mittel tränkt und sodann auf die dem Projektionsapparat zugekehrte Fläche einen hellen Metallüberzug (z. B. Silber oder Aluminium'dure Verreiben des in Pulverform überzuführenden Metalls aufbringt. Die so präparierte Haut kann sodann an der eigentlichen Projektionswand ohneweiters durch Aufspannen oder auf anderem Wege befestigt werden.
Durch das neue Verfahren werden die bisher üblichen Aluminium-sowie die sogenannten Perlenwände entbehrlich, denen gegenüber die neue Wand den Vorzug geringerer Herstellungs- und Betriebskosten hat.

Process for the production of projection surfaces.
The present invention relates to a method for the production of projection surfaces for the presentation of cinematographic images and consists in first soaking the gutta-percha skin in gasoline or another Guttapt-t ± La agent suitable for combining with metal powder and then on the surface facing the projection apparatus a bright metal coating (e.g. silver or aluminum dure rubbing the metal to be converted into powder form. The skin prepared in this way can then be attached to the actual projection screen by stretching it or in some other way.
As a result of the new process, the previously customary aluminum and so-called bead walls can be dispensed with, compared to which the new wall has the advantage of lower manufacturing and operating costs.
