PATENT OFFICE.

Up to now bronzed paper has been made by adding bronze to a suitable one Adhesive mixed with brushes or the like was applied to the paper. One smeared also the paper with glue and then sprinkled bronze on it.

In the first case the bronze lost its pure luster, while after the last the Loss of bronze due to dusting was quite a significant one. Both procedures also had the disadvantage that a uniform covering with bronze could not be achieved could be.

The present procedure eliminates these inconveniences.

The paper α is used in rolls a ¹ and, after bronzing, is passed over a number of heated cylinders bb ¹ , which cause the paper to dry completely. The paper is coated with adhesive by means of an adhesive application brush c or some other suitable device in order to easily accept the bronze dust.

The fan d sucks in air through a pipe g from the bronze container e, which is saturated with bronze dust when the container e is passed through. The stream of air, saturated with bronze dust, goes through the tube h , smears the paper at / and releases the dust to the paper as far as the glue can absorb it. The bronze that has not been taken up is ^{sucked in by the fan d l} through the pipe / r and returned through pipe / into the container e .

The rotating drum f is used to atomize the bronze and, through its more or less rapid rotation, causes a stronger or weaker saturation of the air flow with bronze dust.

If several fans are used, which bronze of different colors the Feeding in paper results in colored and with the use of appropriate cover templates patterned paper.
