Abstract
A photographic film splicer includes a supporting pad or platform on which ends of photographic film strips are supported, and a movable heat block which applies heat and pressure to a heat activated splice tape and the film ends. A heated die attached to the heat block and a plurality of spring-loaded pins supported by the platform apply heat and pressure to a portion of one of the film ends proximate the splice tape to deform a portion of the film strip. The deformed area of the film strip acts as a ramp proximate the splice tape which guides film strips over the interface of the splice tape and the film strip during operations in which the web of photographic film is cut into individual lengths and in which the individual lengths of film are stacked.
