1. A screening apparatus comprising:

  • a plurality of elongated support bars which are generally parallel and transversely spaced with respect to each other;


    a plurality of elongated rail members which are mounted on said support bars and which are generally parallel and transversely spaced with respect to each other, each elongated rail member having a pair of transversely-spaced, longitudinally-extending protrusions; and

    a plurality of screen panel modules mounted on said elongated rail members in side-by-side abutting relationship, each said screen panel module having side portions which extend longitudinally of an adjacent rail so as to be supported thereby, adjacent side portions of adjacent screen panel modules cooperating to secure the screen panel modules to the elongated rail members, each of said mounted screen panel modules being supported only on two sides, each side portion having (a) a longitudinally-extending recess (b) a longitudinally extending resilient skirt peripheral edge portion, and a longitudinally extending groove projecting from the recess in a direction normal to the recess, each protrusion having a transverse cross-section complimentary to its associated recess and groove and being positioned securely therein so as to be engaged between opposing parts of its associated module with the adjacent skirt peripheral edge portions of adjacent modules abutting each other to facilitate retaining the modules in position secured to the elongated rail members, each said elongated rail member providing means for preventing movement of said screen panel modules in a longitudinal direction with respect to the longitudinal axis of said rail elongated member.
