ABSTRACT:
Apparatus for transporting and drying photographic paper which has been chemically processed, includes a roller assembly for transporting the paper through a drying tank. Drying of the paper is accomplished by means of warm air which is propelled by a pump through a distribution duct network. The duct network includes a number of distribution tubes each of which has a tube body and a discharge chute for directing the air from the tube against the paper. Contoured upper and lower surfaces of the tube in combination with individual roller elements, which are spaced apart on a roller shaft, provide turbulence reducing return channels for routing the air, which has been deflected by the paper, back toward the pump.
