Abstract
In accordance with the inventive method, a one-sided coated element, in particular a screen element, is provided with a bonding agent after being cleaned. Subsequently, form elements are inserted into the openings of the elements from the rear side thereof which completely fill the openings and extend therethrough. Thereafter, the coating is applied in a lesser thickness than the height of the protruding form elements. This assures that, with a comparably thick coating, openings of a predetermined geometry are created. For this purpose, a device is preferably used having bars which consist of adjacent, successive tapered , pyramid- or horizontal prism-like form elements. The form elements consist of an elastic material which taper into a sharp pointed edge. Thereby, the form elements may be easily installed and removed and the coating runs off the form elements during application, so that the openings are not covered up by the coating material. In such a manufactured screen element, the openings are formed by parallel running profile wires which are connected with each other by transverse ribs. The coating is applied in comparable large thicknesses on the operating face of the prof…
