Abstract
The present invention is an apparatus for preparation of a coating hopper. A preparation pan is positioned beneath the hopper lip during hopper preparation wherein flow within the hopper is chaotic and the curtain is not stable. The preparation pan includes edge walls spaced apart from the edge guides to stabilize the unsteady curtain within the preparation pan. The invention minimizes splashing and splattering of the coating liquids thereby minimizing contamination of the coating equipment.
