Coating device

Abstract

Abstract Inside it or on the stencil there is a closed hollow body which is open in a slit-like manner to the coating plane. It therefore has a coating slit. The hollow body is of sealing design or is closed off appropriately, such as by a cover or the like which can be attached sealingly. A pressurised air bubble will form in this hollow body. This air is supplied as compressed air or is obtained by the introduction or continuous introduction of the foamed coating medium. The compressed air or another gaseous medium has its pressure set and drives the foamed medium actively through the coating slit and a stencil onto the material or influences the continuous foam feed. It then acts as a spring. For this purpose, the compressed-air operating unit or a corresponding measuring device is connected to the conveying device for the foamed medium. The devices influence one another according to the operating state. <IMAGE>
