Apparatus for supporting screen (12) in a screening machine (10) that will permit long-life of the screen even when subjected to heat and vibration. The screen or wire cloth edge is folded over (30) and fastened or joined (42, 44, 46), with a metal rod (32) inserted down through the foldover space (34). Spring clips (40) or other adjustable tensioning devices attach the steel rod (32) to the screening machine frame (50), thus placing the screen (12) in tension.
