<p>The screen has a rigid framework (1, 2, 3) under tension fastened to a strip (4) and made from electrically non conductive material. A fine- mesh fabric (6) made from electrically conducting material, such as high-grade steel wires fastened to the interior edge of the strip. The fabric is assigned to pressure- active elements (9) with electrical connections separated from each other and connected to a power source. The electrical connections (12, 13) are connected to both sides of the pressure-active elements. The connections are made by soldering.</p> |
