Abstract
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.
