Abstract
A device for holding film strips and the like in proper position on spiral reels or the like such that the film will be held onto the reel in proper spaced relation to permit the flow of the developer about the film for development thereof. The device includes a longitudinally extending body having a transverse dimension which will permit the device to extend across the width of the film and thus the corresponding spiral reel to contact the edges of the film and hold the same against the spirally formed elements of the reel. The device is designed to lock into the reel between the spiral elements thereof and may be used for full or partial strips of film.
Claims15
In combination, a film mounting reel and a film retention device therefore, said combination including:
- a. a film mounting reel having a longitudinally extending core portion and a pair of longitudinally spaced film spacing elements arranged on said core portion, said film spacing elements including a sprially formed support member extending laterally from said core, the longitudinal spacing of said support members provided to receive the image area of the film therebetween;
- b. the film retention device including a longitudinally extending, planar, body portion of a generally resilient material to allow forming thereof for placement thereof into said reel between said spiral supports thereof;
- and,
- c. said body having at least one pair of oppositely directed, transversely extending tab elements, the transverse dimension of said tabs permitting the same to extend transversely into the spiral film supports of said reel for locking between adjacent of such spiral supports to retain the film against one of said spiral supports.
