Abstract

An applicator assembly used in a processor for processing a photosensitive material with a developer liquid, in which an oscillating applicator supports and contacts an open-celled scrubber pad. The developing fluid is pumped through an adapter onto the applicator, which has a plurality of perforations at its front surface contacting the scrubber pad. The developer fluid is distributed through the scrubber pad which serves as a manifold to the surface to be developed and cleans from it unhardened emulsion of the photosensitive material, which passes the scrubber pad, inserted between it and a transport belt. There are provided means to prevent any shift between the applicator and the scrubber pad which might appear due to the oscillating movement of the applicator assembly transverse to the guide motion of the transport belt, which advances the photosensitive material.

Dependent claims

An applicator assembly for processing a photosensitive material with a developer liquid, having an oscillating applicator supporting and contacting an open-celled scrubber pad, said applicator being provided with perforations through which the developer liquid under pressure is directed outwardly to penetrate said scrubber pad to wet and to process a photosensitive layer of a photosensitive material, which is inserted between a transport belt and an outer surface of the scrubber pad, said applicator assembly comprising:

pad holder rods around which longitudinal edges of the scrubber pad are wrapped;
said pad holder rods having shouldered rod ends in operative connection with rod holders to clamp the scrubber pad between the pad holder rods and angular longitudinal edges of a channel sub-assembly of the applicator;
and means for providing an additional contact attachment between the applicator and the scrubber pad to prevent a tightening of the scrubber pad during the oscillating movement of the applicator assembly transverse to the guide motion of the photosensitive material advanced by the transport belt.
