ABSTRACT:
An improved vibratory separator screen in which a wire mesh having least a first pair of opposed end portions each comprising a reinforced edge strip tensioned to a surrounding frame comprises a reinforcing spline member located adjacent each of the opposed end portions with the spline adjacent opposed ends portions being completely encapsulated, such as with cured vulcanized rubber, to fixedly secure the spline member to the adjacent opposed end portion with the mesh at a desired tautness for providing a substantially evenly tensioned mesh when tensioned to the surrounding frame. The completely encapsulated spline adjacent opposed end portions comprise the reinforced edge strips which each have sealed end points. These encapsulated opposed end portions may be provided on all sides of the wire mesh with the reinforced edge strips formed thereby having through holes provided directly through the completely encapsulated spline adjacent opposed end portions to provide eyelets for tensioning the mesh to the surrounding frame.
