<p>A manually operable apparatus (70) for sequentially cutting sections of film (120), each of which includes a visible photographic image, and for mounting the same in a frame (10) for subsequent use in a projector or viewer is described. The apparatus (70) is specifically adapted for use with frames (10) of the type which have a pair of open-ended guides for receiving the film (120). The apparatus (70) includes means for supporting the frame (10) at an acute angle relatively to a plane containing the path of movement of an advancing section of film (120) so that the leading edge (158) of the advancing film (120) is deflected by a portion of the frame (10) in a predetermined direction and along a well-defined path into the open end of each of the two film guides. The apparatus (70) also includes means (88,90) for maintaining a trailing edge portion (159) of the section of film to be mounted in a generally horizontal plane during the deflection of the film's leading edge (158). Accordingly, after the leading edge of the film bottoms out at the closed end of each guide, and the trailing edge (159) is severed from the remainder of the roll of film, the trailing edge (159) moves in a direction to relieve the stresses in the severed section caused by the deflection of the leading edge (158) of the film. This latter movement results in the trailing edge (159) of the severed section being automatically located in the correct position in the frame (10).</p> |
