Abstract
Improvements in the manufacturing by molding of reels for photographic films, consisting essentially of forming the reels by juxtaposition of two molded parts, one of which constitutes the central cylindrical core on which the film is wound, to which end it presents one or more notches for retaining it, which is joined by one of its ends of a disk-shaped head, formed in the molding operation of the central core and centrally provided with a hole, the other piece being constituted by a disk analogous to integral with the core and provided with an extension or central cylindrical lug of a diameter corresponding to the interior of that core, being adjusted with this and, preferably, both adhered to each other by means of an appropriate glue.
