history

In 1884, “J. Leh and G. Langenbach in Bruchsal "a patent under the number DP 23788 for their" apparatus for moistening gummed paper ... for moistening the paper "the same was pulled through a dampening pad between a pressure roller.

The "Hansa" humidifier was offered "for every desk" and as a gift in 1905. His moist pillow remained moist for a long time, even when in use, thanks to an adhesive- sucking thread that was connected to a small water container. A patented flap should largely avoid soiling the papers to be moistened. At the same time, the device was intended as a paperweight, especially for the already moistened letter, which should be permanently closed by the weight of the moistener. The supplier of the novelty at the time was Richard Beckmann in Berlin S., Ritterstraße 37.

In 1905, the patent gazette listed a patent application from Roderich von Bandel for his "envelope and brand humidifier with felt roller plug" under number 70b dated May 17 of that year .

In 1908 the patent for a finger moistener for card players and the like was advertised by Max Kühne at Lüßnerstraße 74 in Leipzig-Lindenau.

For counting banknotes , the paper newspaper in 1919 described a finger moistener made of nickel-plated sheet metal with an enclosed felt disc made of wool. At the bottom of the capsule, a flexible wire, pointed on both sides, protruded through holes so that the container could be attached to the jacket of the money counter.
