ABSTRACT:
Apparatus for drying sheets of photographic material has a group of parallel lower horizontal shafts and a group of parallel upper horizontal shafts which are staggered with reference to the lower shafts. All of the shafts extend transversely of the direction of travel of sheets therebetween and carry elastic rollers which engage and advance the sheets. Certain shafts carry holders for U-shaped guide members which flank the path of the sheets between the rollers on the upper and lower shafts and prevent the leaders of the sheets from curling into the spaces between the upper or lower shafts. The distance between the axes of two neighboring lower or upper shafts is at least 2D and the distance between the upper and lower guide members is less than D, wherein D is the outer diameter of a roller. The spaces between the rows of rollers on neighboring upper and lower shafts serve (a) to provide room for nozzles which discharge streams of hot gaseous fluid to expel moisture from advancing sheets and (b) to provide room for evacuation of moisture-laden fluid.
