Abstract
A method of processing material in which the material is held on the outside periphery of a drum and processing solution is applied at least twice to the sensitized surface of the material as the drum rotates. The total volume of solution applied is less than 300 ml/sqm of material being processed.
Claims16
A method of processing chemically sensitive materials in which the material is held on the outer periphery of a drum, the sensitized surface facing outwards, wherein processing solution is applied at least twice from a reservoir to the surface of the material, the total volume of solution applied to the material having a maximum of 300 ml/sqm of material to be processed.
Apparatus for processing chemically sensitive materials including a drum processor on which the material to be processed is mounted, the sensitive surface of the material facing outwards, a supply of processing solution, the volume of said supply being substantially equal to or less than 300 ml/sqm of the material to be processed, and means for repeatedly applying the solution to the surface of the material.
9 Apparatus as claimed in claim 8 wherein the means for repeatedly applying the solution to the surface of the material comprises a driven roller.
Apparatus as claimed in claim 9 wherein the drum and the driven roller are positioned to have a gap of up to 0.5 mm between them.
Dependencies are inferred from the claim text.
