Abstract
A photosensitive material-drying apparatus for drying a photosensitive material after being dipped in a treatment solution to wet the same. Water-absorbing rollers for contact with the same surface of the photosensitive material are provided in the vicinity of a photosensitive material-introducing inlet, and are arranged along a direction of transfer of the photosensitive material. The water-absorbing abilities of the water-absorbing rollers is increased progressively in the direction of transfer of photosensitive material.
Claims22
In a photosensitive material-drying apparatus for drying a photosensitive material after being dipped in a treatment solution, the improvement wherein a plurality of water-absorbing rollers for contact with the same surface of said photosensitive material are provided in the vicinity of a photosensitive material-introducing inlet, said water-absorbing rollers being arranged along a direction of transfer of said photosensitive material, wherein, prior to any of said rollers having absorbed any water, the water-absorbing abilities of said water-absorbing rollers increases progressively in the direction of transfer of said photosensitive material.
In a photosensitive material-drying apparatus for drying a photosensitive material after being dipped in a treatment solution, the improvement wherein a plurality of air-permeable water-absorbing rollers for contact with the same surface of said photosensitive material are provided in the vicinity of a photosensitive material-introducing inlet, said rollers being arranged along a direction of transfer of said photosensitive material, said rollers comprising a hollow metal member having a plurality of openings formed therethrough, a pair of shafts extending outward from opposite ends of said hollow metal member, at least one of said shafts being hollow and being connected to a suction pressure source, amounts of air drawn through said openings prior to any of said rollers having absorbed any water, increasing progressively in the direction of transfer of said photosensitive material.
