ABSTRACT:
The present invention is a criss-cross flow hopper which provides even fluid distribution. The flow hopper includes the first and second hopper half each having a planar surface and a cavity which cooperate to form an inner chamber and an exit slot. A first and second insert are securable to each hopper half in the cavity. These non-contacting inserts form within the chamber first and second half flow slots which direct fluid away from the exit slot but then the fluid combines in a damping chamber bounded by the inserts. The fluid is then directed to the exit slot to the substrate to be coated.
