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.
Claims3
In combination:
- a first strip of photographic film having a top and bottom surface;
- a second strip of photographic film having a top and bottom surface;
- a splice tape bonded to the top surfaces of adjacent ends of the first and second strips to splice the first and second strips together with their ends in abutting relationship, the splice tape defining a raised spliced area on the adjacent film strip ends wherein the spliced area has a top surface which is above the top surfaces of the first and second film strip and has an edge generally transverse to a longitudinal axis of the first and second film strips and forms a discontinuity between the top surface of the first film strip and the top surface of the splice tape;
- and
- a ramp positioned on and extending above the top surface of the film strip proximate the edge of the splice tape outside of the spliced area, the ramp having an inclined portion positioned on a side of the ramp away from the edge of the splice tape.
