A device (,) for the intermediate storage of photographic material (,) in sheet form includes an entrance (,) for receiving the material (,), an exit (,) for discharging the material (,) and several rotatably supported rollers (,) which are provided to transport of the material in sheet form (,) from the entrance (,) to the exit (,) and can be driven by at least one drive means (,). A monitoring means (,A,,B) for monitoring positions of intermediately stored sheets (,) of the photographic material (,) is also provided. A control means (,) controls the rotation speeds of the driveable rollers (,) in such a way that during operation the rotation speed of at least one of the rollers (,) can be adjusted independently of the rotation speeds of the other rollers (,) in response to the monitored positions.

Device for intermediate storage of photographic sheet material

Relatively short sections of photographic roll films (such sections can consist of a single film frame or of two or another small number of film frames) are provided with elongated strip-shaped extensions for convenient transport through a copying machine. Extensions are severed from the leader of a roll of convoluted flexible material having a width matching the desired length of an extension, and one end of a freshly severed extension is caused to overlap one end of a film section so that the extent of overlap is not more than the width of a frame line between two neighboring frames of a roll film. One side of each extension is fully coated with a layer of hotmelt, and the extension is sealed to the respective film section by a narrow elongated heating element which is moved against the overlapping ends of the film section and the properly oriented extension. The roll can be subdivided into wider or narrower extensions, depending upon the width of film sections which are to be connected with extensions.

Method of and apparatus for applying flexible extensions to sections of

Apparatus for advancing roll films in a copying machine on a table which is located above the floor at a level less than the length of a film. The apparatus has a film channel and advancing rolls which can engage one end portion of a film to advance the film past a monitoring device preparatory to copying and/or past a copier subsequent to monitoring. The other end portion of the film is frictionally or clampingly held in a recess or on a supporting surface adjacent the inlet of the film channel so that the median portion of the film forms a loop which does not reach the floor beneath the table. A wiping device with two brushes can be installed adjacent the recess to wipe both sides of the film while the film advances into the channel so that the size of its looped portion is reduced.
