Abstract
A roller to be used in apparatus for wet treatment of photographic material comprises a hollow metallic core and two inserts with coupling shafts provided therein. A coat of chemically resistant thermoplastic material is applied around and sealingly surrounds the core to protect it from the corrosive action of media used in the wet treatment process. The outer surface of the thus coated roller is thereupon machined to a high-quality finish.
