Abstract
An apparatus and method for treating one side of a moving web includes a pair of laterally spaced vertical end members. The web to be treated passes in a downwardly extending loop around the lower arcuate edges of the end members and is sealed thereto by tension in the web. The web and end members form a trough containing a flowable treatment material, and the web moves past the flowable material to be contacted and treated thereby. Guide means direct the web downwardly to the inlet side of the trough and upwardly from the exit side of the web-formed trough.
