Description

Process for the production of glass signs It is known per se Paint spreads at any point of the most varied of materials by means of a Scrape or scrape off spatulas with straight and sharp edges.

The idea of the invention now consists in the purposeful application of this Measure or the use of such spatulas to simplify and cheaper production of glass signs.

Glass signs with a simple writing and drawing were namely so far either painted with a brush, which takes a lot of practice and time took apart from the fact that such glass-childers couldn't look clean because it was impossible to have the same thickness everywhere, especially with finer drawings and to be applied with sharp contours. Or such glass signs were placed using the metal foil separation process here.

This procedure almost required more time, practice, and expertise. After all, you had to go through the steps following this procedure, in order to only cover the most important operations to mention, clean the glass pane, then apply a gelatin solution, then "vas was very difficult to pull on the metal foil and use a rubber, # valze roll on, dry the damp film on it, pause the drawing and press Cut out with a knife with a sharp point.

This latter work is known to be very difficult, especially when fine sheets have to be cut. Then there are the many reworking tasks, which already require cutting out the foil, and removing the gelatin water that has dried on the acus-cut areas, which again injures the cut edges very easily. This is then followed by the subsequent stroking - the background of the font, the lifting of the remaining foil letters, the cleaning out of the font, etc.

The metal foil cutting process. is, therefore, as from the foregoing excellent, very cumbersome, time-consuming, requires great technical skills and in spite of all this, it results in the simplest script and decorative design not always perfect results.

On the other hand, the new procedure mentioned at the beginning now demands only four work steps that can be carried out by any inexperienced and thereby the production of previously unattainable high-quality glass shields-in of great decorative effect in a fraction of the time as it has been for the simplest up to now Signs was needed, allows.

Said four operations are f he following: First, cleaning of the glass sheet, then plating of the color, after which drying Aufpausen the drawing or writing, and then immediately the sharp contours AusstDßen of writing or drawing using the spatula. Depending on its leadership and the profiling of the blades of the scraper, a great variety of forms in writing and drawing can be effortlessly achieved. For example, according to the new method, when using scrapers with more or less narrow cutting edges, you can achieve stalk patterns in a simple continuous or-ü, interrupted or intersecting course with then remaining color islands, which cannot be carried out by any other working method, let alone in this razor sharpness are feasible.

So it becomes more familiar through the use of familiar ways of working Tools in a particularly economical way the production of Glass.children enables. Only in this purposeful application of known working methods and The inventive lies in tools.

The drawing illustrates some of the known spatulas which are particularly suitable for carrying out the method, namely: .. Fig. 5 a spatula with adjustable cutting edges, Fig. 6 a small-scale spatula in use, with the hatched area representing the piece of the paint layer that has already been pushed away in one line ..
