Abstract

Process and device for feeding a coating material onto a moving web (2) under pressure through a feed channel (12). The feed channel (12) extends transversely to the web and has a width corresponding to the web width. It is connected to a pressure equalisation chamber (8) into which the coating material is fed continuously. The amount of coating material fed to the web is adapted to the surface characteristics of the web and the web rate. To achieve this, the volumetric flow from the pressure equalisation chamber (8) is controlled by the feed channel (12), whereas the dry substance concentration of the coating material and the coating width on the web are kept constant. The levelling of the coating on the web is carried out by means of a flexible coating blade (doctor) (16) which, at least at its outlet end, forms an inner side wall of the feed channel. The blade forms an acute angle with the web and adjustment devices (18, 19) are provided for controlling the contact pressure of the blade against the web, both over their entire length and also individually at a plurality of individual points at longitudinal distances on the blade. <IMAGE>
