Abstract
Abstract Individual photographic films are removed from a composite film comprising a flexible carrier strip or strips to which the films have been adhesively bonded along one edge or both edges during the production of reprint photographs, by inserting a deflector under the film while bending the carrier strip around a corner to stretch the adhesive, thereby separating the film from the carrier strip. The apparatus employed comprises an elongated frame mounting the composite film, drive means for driving the composite film the length of the frame, guide means including a corner for guiding the movement of the film, and deflector means positioned adjacent the corner for insertion under the film and moving it angularly with respect to the carrier strip as the strip moves around the guide corner, thereby separating the film from the carrier strip.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
185 words
Apparatus for removing a plurality of photographic films from an assembly of films secured adhesively along one of their longitudinal edges to an elongated, flexible carrier strip, whereby the central portions of the films are spaced from the carrier strip, the apparatus comprising: (a) a frame having an outer support surface for supporting the film and the strip assembly during movement of the assembly longitudinally in a film-removal direction, the support surface having a film-removal end, (b) a film deflector mounted on the frame and having a film-engaging outer surface and an inner end disposed longitudinally rearward of the film-removal end of the support surface, the outer surface of the deflector extending forwardly of the film-removal end of the support surface of the frame angularly outward with respect to the plane of the support surface of the frame, (c) the film deflector being arranged to engage only the film component of the film and strip assembly, (d) the film-removal end of the support surface of the frame laterally adjacent the deflector forming a carrier strip bending edge for separating the carrier strip from the films.
Claim 2
Dependent Claim

Apparatus for removing a plurality of photographic films from an assembly of films secured adhesively along one of their longitudinal edges to an elongated, flexible carrier strip, whereby the central portions of the films are spaced from the carrier strip, the apparatus comprising: (a) a frame having an outer support surface for supporting the film and the strip assembly during movement of the assembly longitudinally in a film-removal direction, the support surface having a film-removal end, (b) a film deflector mounted on the frame and having a film-engaging outer surface and an inner end disposed longitudinally rearward of the film-removal end of the support surface, the outer surface of the deflector extending forwardly of the film-removal end of the support surface of the frame angularly outward with respect to the plane of the support surface of the frame, (c) the film deflector being arranged to engage only the film component of the film and strip assembly, (d) the film-removal end of the support surface of the frame laterally adjacent the deflector forming a carrier strip bending edge for separating the carrier strip from the films.
Claim 3
Dependent Claim
58 words
The apparatus of claim 1 including a film support extending laterally from the deflector substantially in the plane of the support surface of the frame and spaced forwardly of the bending edge of the support surface for supporting film downstream from the carrier strip as the latter is bent around the bending edge and removed from the films.
Claim 4
Dependent Claim
55 words
The apparatus of claim 1 including: (a) a film and carrier strip assembly take-off reel mounted on the frame upstream from the film-removal end, (b) a carrier strip take-up reel mounted on the frame downstream from the film-removal end, and (c) reel drive means on the frame engaging the take-up reel for rotating the latter.
Claim 5
Dependent Claim
33 words
The apparatus of claim 1 including film and carrier strip assembly guide means on the frame for aligning the film longitudinally with the deflector and the carrier strip longitudinally with the bending edge.
Claim 6
Dependent Claim
139 words
The apparatus of claim 1 including: (a) a film support extending laterally from the deflector substantially in the plane of the support surface of the frame and spaced forwardly of the bending edge of the support surface for supporting film downstream from the carrier strip as the latter is bent around the bending edge and removed from the films, (b) a film and carrier strip assembly take-off reel mounted on the frame upstream from the film-removal end, (c) a carrier strip take-off reel mounted on the frame downstream from the film-removal end, (d) reel drive means on the frame engaging the take-up reel for rotating the latter, and (e) film and carrier strip assembly guide means on the frame for aligning the film longitudinally with the deflector and the carrier strip longitudinally with the bending edge and take-up reel.
Claim 7
Dependent Claim
121 words
The apparatus of claim 1 wherein the films are secured adhesively along both of their opposite longitudinal edges to a pair of laterally spaced elongated flexible carrier strips and the film-removal end of the support surface of the frame laterally adjacent both sides of the deflector form a pair of carrier strip bending edges for separating the carrier strips from the films, and the apparatus includes a film support extending laterally from opposite sides of the deflector substantially in the plane of the support surface of the frame and spaced forwardly of the bending edges of the support surface for supporting film downstream from the carrier strips as the latter are bent around the bending edges and removed from the films.
Claim 8
Dependent Claim
117 words
The apparatus of claim 1 wherein the films are secured adhesively along both of their opposite longitudinal edges to a pair of laterally spaced elongated flexible carrier strips and the film-removal end of the support surface of the frame laterally adjacent both sides of the deflector form a pair of carrier strip bending edges for separating the carrier strips from the films, and the apparatus includes: (a) a film and carrier strip assembly take-off reel mounted on the frame upstream from the film-removal end, (b) a pair of carrier strip take-up reels mounted on the frame downstream from the film-removal end, and (c) reel drive means on the frame engaging the take-up reels for rotating the latter.
Claim 9
Dependent Claim
54 words
The apparatus of claim 7 including strip drive means on the frame intermediate the bending edges of the support surface and the take-up reels arranged to engage the carrier strips for pulling the film and carrier strip assembly in the downstream direction, the reel drive means on the frame frictionally engaging the take-up reels.
Claim 10
Dependent Claim
242 words
The apparatus of claim 1 wherein the films are secured adhesively along both of their opposite longitudinal edges to a pair of laterally spaced elongated flexible carrier strips and the film-removal end of the support surface of the frame laterally adjacent both sides of the deflector form a pair of carrier strip bending edges for separating the carrier strips from the films, and the apparatus includes: (a) a film support extending laterally from opposite sides of the deflector substantially in the plane of the support surface of the frame and spaced forwardly of the bending edges of the support surface for supporting film downstream from the carrier strips as the latter are bent around the bending edges and removed from the films, (b) a film and carrier strip assembly take-off reel mounted on the frame upstream from the film-removal end, (c) a pair of carrier strip take-up reels mounted on the frame downstream from the film-removal end, (d) strip drive means on the frame intermediate the bending edges of the support surface and the take-up reels arranged to engage the carrier strips for pulling the film and carrier strip assembly in the downstream direction, (e) reel drive means on the frame frictionally engaging the take-up reels for rotating the latter, and (f) film and carrier strip assembly guide means on the frame for aligning the film longitudinally with the deflector and the carrier strips longitudinally with the bending edges and take-up reels.
