Patent ID: 6962626

Claim:
A venting assembly adapted for use with a drum photoreceptor dip coating apparatus, the apparatus having a tank for holding a dip coating liquid, at least one dip tube vertically arranged within the tank, each dip tube adapted to receive (i) a flow of the dip coating liquid, and (ii) a drum to be coated with the liquid, the venting assembly comprising: a plurality of vent tubes arranged within the tank to uniformly surround each dip tube, each vent tube defining a vapor withdrawing end positioned proximate a surface of the dip coating liquid and an outlet end; a venting manifold in flow communication with each outlet end of the plurality of vent tubes; whereby upon inducing a pressure differential between (i) the vapor withdrawing end of each vent tube and (ii) the venting manifold to thereby cause vapor flow into the venting manifold, vapors residing above the surface of the dip coating liquid are removed therefrom in a uniform fashion thereby promoting uniform drying of the drum coated with the dip coating liquid.
