<p>Apparatus for treating a web with treatment fluid comprises a two part housing (32,34) defining a recess (62) for receiving the web and a fluid distribution system comprises a series of passages (46,48,50,52,54,56,58) connected in a whiffletree configuration for dividing and subdividing the treatment fluid to supply treatment fluid to the recess (62) at a plurality of locations across the recess to uniformly treat the web with the treatment fluid. In another embodiment the process or comprises a pair of plates (90,92) defining a recess (98) for receiving a web. The plates (90,92) have at least one pair of elongated liquid injection openings (100) extending transversely of the recess (98) on opposite sides of the web respectively in juxtaposed relationship for injecting liquid into the recess (98). The plates further include at least one pair of elongated evacuation openings (102) extending transversely of the recess (98) on opposite sides of the web respectively in juxtaposed relationship for evacuating liquid from the recess (98). A whiffletree liquid distribution system (114,116,118,120,122,124,126) is associated with each of the openings (100,102) to supply liquid to the injection openings (100) and to evacuate liquid from the evacuation openings (102). <IMAGE></p> |
