Abstract
Successive exposed photographic films are connected, either individually or in groups of two or more, to discrete sheet-like leaders which are transported along an elongated first path extending through the baths and the dryer of a developing unit. The leaders are separated from the respective webs downstream of the developing unit but upstream of a copying unit for developed films, and the separated leaders are directed into a second path to be gathered in a receptacle. The separation involves severing the leading end of each web close behind the respective leader, and the thus separated webs are caused to continue to advance along the first path through a magazine and thence into the copying unit. The severing mechanism includes a stationary first knife and a second knife which is movable relative to the first knife between a first position in which an oncoming leader is free to enter the second path and a second position in which the knives cooperate to sever the leading end of the web behind the leader in the second path.
