ABSTRACT:
At least one group of at least three elongated slats are mounted side by side on a frame for longitudinal reciprocation to form a conveyor, the slats being connected to adjustable drive mechanism which is operable in a first position of adjustment such that there are always a greater number of slats of each group moving simultaneously in a conveying direction, with the remaining slat or slats of each group moving in the opposite direction, and in a second position of adjustment such that all of the slats of each group move simultaneously in the conveying direction, to initiate movement of a load to be conveyed, whereupon the drive mechanism is adjusted to said first position of adjustment. In one embodiment of the invention, elongated flexible seals are provided between adjacent pair of slats, each seal being secured to one of the slats of the pair and slidably engaging the other slat of the pair, whereby to form a substantially non-porous conveyor. In another embodiment the slats are arranged to provide between adjacent slats a spacing which increases progressively in a conveying direction, whereby the conveyor functions additionally as a particle separator.
