Holder for photographic processing machines |
摘要 |
A photographic processing machine has a plurality of rollers for transporting the photographic materials through a processing bath. According to this invention, alternate ones of adjacent rollers are provided with a flexible casing subject to internal hydraulic pressure. The flexible casing is formed of a textile fabric. The fabric encased rollers each have openings through their walls, the film treating bath liquid fed under pressure to the interior of each roller and then through the wall openings. The flexible textile casing thereby expands, to produce squeezing force on the photographic material being processed as the material passes between a rigid roller and its associated textile encased roller.
