ABSTRACT:
Several illustrative embodiments of this invention are shown and described. The screen deck for screening machines is assembled from rectangular screen members, preferably formed from a suitable synthetic material. These screen members abut one another directly to form a continuous screen surface. The screen members have at the edges of their undersides projections which complement one another in pairs along the abutting surfaces on only the longitudinal edges of the members. Longitudinally oriented support struts underneath the screens have aligned holes which engage the projections and thereby sustain the entire screening surface.
