Abstract
Apparatus for uniting exposed photographic roll films into a continuous web which is already for transport through a developing machine has a housing which is lightproof and has two inlets, one for admission of cassettes which contains exposed films and the other for reception of exposed films. Successive cassettes which are introduced through the first inlet are conveyed into the range of a film removing mechanism which automatically removes the films, without breaking the respective cassettes, and the removed films are transported to a splicing device. If the position of roll film in a cassette is such that the film cannot be expelled by the removing mechanism in the housing, the cassette is opened in a darkroom and the film which is removed from the opened cassette is introduced though the second inlet. Such film is transported to the splicing device, preferably along a path a portion of which coincides with a portion of the path for transport of films from the film removing mechanism to the splicing device. One of the inlets is closed when the other inlet is open, and vice versa.
