ABSTRACT:
A screening screen assembly for a vibratory screening machine including an apertured plate, and a bonded subassembly of an undulating support screen and fine screening screen and finer screening screen bonded to each other by a fused plastic grid and bonded to the apertured plate. A method of fabricating a screening screen assembly for a vibratory screening machine including the steps of providing a support screen, superimposing a plastic grid onto the support screen, superimposing a finer screening screen onto the fine screening screen, applying heat and pressure to the superimposed screens to fuse the plastic grid and thereby form a flat bonded laminate subassembly by causing the fused plastic grid to permeate the fine screen and the finer screen and the support screen, forming the bonded laminate subassembly into an undulating shape, providing an apertured plate, and bonding the undulating bonded subassembly to the apertured plate.
