ABSTRACT:
A screen assembly for a vibratory screening machine including a plurality of superimposed screens, channels on the edges of the screen assembly, and a plurality of hollow plastic channeling strips fused into the plurality of superimposed screens. The hollow channeling strips may have metal rods therein, and the plurality of superimposed screens may be bonded to an apertured plate. A method of fabricating a screen assembly for a vibratory screening machine including the steps of laying a plurality of plastic tubes into grooves of a fixture, superimposing the plurality of screens over the plastic tubes, and applying a heated platen to the screens to thereby cause the plastic tubes to fuse into the screens. The hollow plastic tubes may have metal rods therein, and the plurality of screens may be bonded to an apertured plate before the hollow plastic tubes are bonded to the screens.
