A screening media for use in vibrating screen devices that fractionize crushed stones or gravel. The screening media is made by extruding a fiber-reinforced rubber or polymeric material to form a strip in a length longer than that needed to make individual screening mats for use in the vibrating screen devices. Screening apertures are then punched in the strip, and the apertured strip is cut into individual mats. The extruded strip includes side portions configured to connect to support structures of the vibrating device. Prior to the cutting step, the apertured strip can be maintained in the form of a coil or a long-length element. |
