Film reel with film-threading tensioning flange

摘要

In a preferred embodiment, there is a film reel having a film- threading film-retaining core, the core containing free-space for threading a mounting-end of a film to be would on the reel, and across at least a portion of the core's free space there being a floor mounting the outer reel structure onto the inner core structure that is mountable on a driving spindle, with spaced-apart posts extending upwardly from the floor and the posts being spaced from each of the mounting spaces inside core walls and the space's inside surface of the outside walls of the core, with each of the posts anchored by anchoring structure connected to the core's inside core structure, the upwardly extending posts having a large exaggerated arcuate surface providing large surface area for contact with film threaded thereagainst, there being a flange extending angularly radially inwardly from the inside surface of the outside wall of the core, the flange extending between second and third posts and extending radially inwardly sufficiently to press against the threaded film when threaded within the threading space of the core such that the pressed threaded film is held tautly.
