Abstract

A reel for strip-like recording substrates, in particular photographic films, with a slot provided in the reel core and at least one hook provided therein for fixing the end of the tape inserted into the slot, wherein the upper and lower side of the hook are joined together by an oblique face at the end opposite the film insertion side, in such a manner that the hook tapers towards the hook end and the hook surface is longer than the hook under-side, and wherein any chosen sections parallel to the under-side of the hook through the oblique face produce arcuate lines of intersection, ensuring secure insertion of the film end.
