Apparatus for treating a moving web

摘要

Apparatus for extracting liquid from a moving web having reduced suction requirements, conserving space and being more servicable may be provided through the use of an upper wear surface constructed of ultra high molecular weight polyethylene having a transverse slot therein over which the web passes, together with elongated transverse inserts for blocking end portions of the slot responsive to movement of the web from side to side as it drifts or wanders during its movement over the slot.
