Abstract

Film developing appts. has a developing section with a number of troughs contg. developing liq. and roller pairs in the troughs for moving film through the troughs. The ends of the axles of the lower rollers are mounted in grooves allowing vertical movement of the rollers, and the lower rollers are flexible and made of such a matl., esp. polyurethane foam, that the total s.g. of each lower roller is smaller than that of the developing liq. in the trough contg. the roller. Provides uniform adjustable roller pressure.
