  • conveyor slats each having an upper portion including the said upper side portions, and laterally spaced apart depending leg portions, each with a laterally outwardly directed flange that is offset vertically below the upper side portion on its side of the conveyor slat;

    a longitudinal support beam positioned between each adjoining pair of conveyor slats, below adjacent upper side portions of the adjoining conveyor slats;

    a longitudinal bearing/seal member on each support beam, extending along and connected to said support beam, said bearing/seal member presenting said bearing/seal surface; and

    said longitudinal bearing/seal members having side portions that project laterally outwardly from opposite sides of the support beams, each into a position that is above an adjacent outwardly directed flange on an adjacent depending leg of an adjoining conveyor slat, for blocking upward movement of the conveyor slats up off of the bearing/seal member.
