ABSTRACT:
A sieve screen deck, the screen of which comprises a plurality of horizontal wedge wires connected to an array of backing bars running longitudinally of the screen parallel to its fall line. The screen is connected to a frame at its two ends, at least one end being connected by resilient means such that the screen may vibrate and flex under the influence of rapping or vibrating means. Side walls are provided along sides of the sieve screen, to prevent material flowing over sides of the screen, are also formed of a resilient material in order that they do not substantially impede the ability of the sieve screen to vibrate and flex under the influence of the rapping or vibrating means.
