Apparatus for applying a processing liquid to a sheet or web material

摘要

The deposit of solid residue upon the exit squeeze rollers following immersion of sheet- or weblike materials in a bath of treatment liquid and the transfer of the residue to the materials themselves is avoided by an applicator which applies a film of moistening liquid to the periphery of one such exit roller so that the exit rollers are sufficiently wetted as to dissolve the solid residue before a sheet or web passes therethrough.
