ABSTRACT:
Conveyor assemblies adapted for use in painting booths, embodying conveyor units having upper and lower frames spaced apart by post portions aligned in the direction of travel. A dust cover encloses the drive mechanism and has a top wall between the upper and lower frames. A slot is provided to permit passage of the aligned post portions, and the slot is covered by a resilient flexible flap which can be displaced by the post portions as they travel through the slot. The drive mechanism includes alternative drive chains, one of which has a pusher for effecting advance of the units, the other of which has a bifurcated coupling which may effect both advance and retraction of the units along their path of travel. The lower frame has swivelable wheels which may ride in the elevated wheel-guide tracks in the painting booth to provide stabilization of the frame against lateral sway.
