<p>An apparatus for the development of microfilm passes film successively through different work stations, such as the developer bath, fixing bath, preliminary washing bath, second washing bath and a drying stage. The film moves in a horizontally arranged track with the aid of a motor driven pair of rolls. The apparatus is characterized by a liquid circulation system in which each vessel supplying a liquid station with a liquid and designed as a transport container is equipped with a supply line and a suction line. The suction line moves the liquid to a bath by means of a liquid pump and by way of pressure lines through a heating means. A bath may be associated with each work station. In the bath the liquid is sprayed against the bottom side of the film travelling in the horizontal direction and is returned through a liquid and film guiding body and the supply line into the vessel.</p> |
