Abstract

Die Erfindung betrifft ein Verfahren zum Streichen eines feuchten oder beleimten lagenförmigen Papiers aus Rohpapier, Rohpappe oder ungestrichenem Karton. Um eine effizientere Möglichkeit zum Streichen von Papier zur Verfügung zu stellen, umfasst das erfindungsgemäße Verfahren die folgenden Schritte
- Aufbauen von Gasdruck in einer Leitung
- Erzeugen eines Druckwechsels in der Leitung
- Verwirbeln und Mitreißen von Streichpartikeln in die Leitung
- Sprühen von verwirbelten Streichpartikeln aus der Leitung auf das Papier,

wobei die Streichpartikel nach dem Aufsprühen auf der Oberfläche des Papiers anhaften.

The invention relates to a method for coating a wet or glued sheet-like paper from raw paper, raw board or uncoated cardboard. In order to provide a more efficient way of coating paper, the method according to the invention comprises the following steps
- Building gas pressure in a pipe
- Generating a pressure change in the line
- Swirling and entrainment of coating particles in the pipe
Spraying swirling coated particles from the pipe onto the paper,

wherein the coating particles adhere to the surface of the paper after spraying.
