Floating film photographic developing apparatus
Abstract
Abstract Developing apparatus for the rapid development of photographic silver halide elements, e.g., sheets or plates having a series of spaced solution-applying plates having (1) rows of spaced orifices of small diameter for supplying photographic treating solutions to the surface of the applying plates and to the surface of the elements passed across the applying plates, and (2) alternate rows of spaced orifices of greater diameter for removing excess solution; characterized in that between the applying plates are pressure or squeegee rolls for removing excess solutions, drip pans for the solutions, cover plates extending over the applying plates and flexible sealing strips at the entrance and exit ends of the cover plates, which strips are adapted to press against the back surface of the photographic elements. The apparatus can have an associated drying chamber adjacent the final solution-applying plate.
