APPARATUS FOR THE LIQUID PROCESSING OF A SURFACE OF A MATERIAL IN THE FORM OF A SHEET, A WEB OR A PLATE

摘要

An apparatus is described for the liquid processing of a surface of a moving sheet, web or plate. Processing liquid is supplied to said surface via a plurality of elongate discharge orifices extending across the width of said moving sheet or web in a non-perpendicular direction with respect to the sense in which said sheet, web or plate is advanced within said apparatus. By the said non-perpendicular arrangement of the discharge orifices air bubbles entrapped in the processing liquid as a result of pumping can be carried off so that no processing faults occur.
