ABSTRACT:
A device for removing volatile noxious liquids from photographic film has a film passage with an inlet and an outlet. Inwardly adjacent the film passage the opposite surfaces of the passage have recesses which are connected to a suction source; the inlet is slightly larger than the film so that the suction can act already on the film before the same enters the inlet, so that vapors forming outside the inlet are aspirated by the suction. A portion of the adhering liquid is also removed by this suction. Subsequently the device has in these surfaces two additional recesses which are also connected to a suction source, to remove additional liquid. Downstream of these additional recesses a series of air outlet openings is provided in each of the surfaces; these openings face in upstream direction and receive air under sufficient pressure so that any liquid still adhering after the web passes the additional recesses is forced to flow in upstream direction and to the additional recesses, to be aspirated by the suction therein, while the air at the same time dries the film which then emerges from the device in dry condition.
