ABSTRACT:
An arrangement for wet processing webs of photographic paper includes a housing, a set of parallel driven shafts mounted in an upper portion of the housing, and a set of parallel driven shafts mounted in the lower portion of the housing. Each shaft carries first web-contacting rollers on its end portions and a group of second web-contacting rollers on its central portion. A band-engaging roller is arranged between each first roller and the corresponding group of second rollers. A first conveyor band is trained over the set of band-engaging rollers nearest one end of the respective shafts while a second conveyor band is trained over the set of band-engaging rollers nearest the other end of the respective shafts. The conveyor bands are provided with gripping elements which clamp webs of photographic paper entering the housing so that the conveyor bands can draw the webs through the housing. Each shaft is rotatably supported by a pair of bearing units located in the regions of the respective band-engaging rollers. The bearing units for the upper shafts support the latter from below while the bearing units for the lower shafts support such shafts from above.
