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 the surface via a plurality of elongated discharge orifices extending across the width of said moving sheet or web in an oblique angle with respect to the direction in which said sheet, web or plate is advanced within said apparatus. By the oblique arrangement of the discharge orifices air bubbles entrapped in the processing liquid as a result of pumping can be carried off and processing faults reduced.
