Abstract

A device for winding strips of photographic film inside a housing. A film-guide slot opens into the housing's approximately cylindrical interior. A film reel rotates freely in the housing interior without a positive drive and demarcates, in conjunction with the inner surface of the housing, a more or less annular film-guide channel. The film-guide slot opens more or less tangentially into the interior channel.
