Description

Verfahren zur Herstellung von Sieben und Filtern. Nach vorliegendem Verfahren stellt man E Siebe oder Filter her, indem man das photographische Bild eines Siebes oder Rasters in natürlicher Größe oder in irgendeinem maßstäblichen Verhältnis auf eine ätzbare Platte überträgt und die nicht belichteten Stellen anätzt.Process for the manufacture of sieves and filters. According to the present Process one makes E screens or filters by taking the photographic image a screen or grid in natural size or in any full-scale Ratio transfers to an etchable plate and etches the unexposed areas.

Diese geätzte Platte benutzt man dann . als Prägeoriginal zur Herstellung von Matrizen. Präpariert man vor oder nach der Prägung diese Matrizen mit einer Lösung von Gelatine, Leim oder ähnlichen Stoffen, die durch Behandlung mit chemischen Reagenzien oder Licht in Wasser unlöslich gemacht werden können, oder mit alkoholischen, benzinischen . oder ätherischen Lösungen von Wachs, Harz oder Gummiarten, so erhält man im galvanischen Bad siebartige Niederschläge.This etched plate is then used. as an embossed original for production of matrices. If you prepare these matrices with a Solution of gelatin, glue or similar substances obtained by treatment with chemical Reagents or light can be made insoluble in water, or with alcoholic, petrol. or essential solutions of wax, resin or types of rubber, so obtained sieve-like deposits are made in the galvanic bath.
