Abstract
A method of constructing a frame ( ) for a filtering screen from a polymer material is described in which a wire frame reinforcement is wholly encapsulated during the frame moulding process so that two parallel spaced apart wires extend through each of the intersecting orthogonal ribs ( ) which define the open area of the frame ( ) across which the wirecloths ( ) are stretched. The surfaces of the frame ( ) in which the wirecloths ( ) are embedded are formed with ridges ( ) and the crests of the latter extend to different heights. The crests are softened by heating during the manufacturing process and the wirecloths ( ) stretched over the frame ( ) are forced into the softened crests after which the assembly is allowed to cool and cure. The frame ( ) is re-usable by stripping wirecloths ( ) from the top of the frame ( ) and fitting fresh wirecloths over the plastics material and heating the regions which are to encapsulate the fresh wirecloth.
