Abstract (en)
A method for producing panels for a screen for machines that is suitable for placing in front of or around the machine, in which the starting material is steel plate, and in which use is made of an angle bending device. The screen for machines is assembled from uprights and from panels fitted between said uprights. In the method a first type of panel is produced in one piece from a steel plate that is bent in edge areas by means of the angle bending device. Holes for fixing to the uprights are made in the bent edge areas. In the method a second type of panel is produced by forming strips of steel plate by means of the angle bending device to a bent, angled section which has legs. Furthermore, in the method holes for fixing to the uprights are provided in one leg of the angled section. A framework is constructed from the bent, angled sections, in which in each case the leg of each angled section that has been provided with holes lies on the periphery of the framework and another leg lies on the front side of the framework. A piece of mesh, a sheet or something of that type is fitted in the framework. <IMAGE>
