Abstract
An apparatus and method for splicing photographic films is disclosed, where the films are conveyed along a path and supported by a track element. Upon being positioned to receive a splice, the films are clamped between a movable splice pad and the track clement. The clamping action produced by the movable splice pad substantially eliminates the problem of film foldovers caused by curling at the trailing end of a film. A splice head is lowered to apply a splice tape to the films, thereby forming the splice. The films are spliced together in a flattened state, producing a continuous web of film which can be wound onto a roll or core for further processing.
