Abstract

Abstract A method is provided for winding a photographic film into a spool with fastening elements for the end of the film on its core. The spool is rotatably mounted in a cassette with a slotlike opening. The opening and the end of the film are brought together into the insertion position with the fastening element on the spool core aligned with the opening. A guide tongue is then inserted within the slot and the end of the film is introduced into it and through the opening into contact and securement with the spool core. Then the guide tongue is withdrawn and a suitable length of the film is wound on the spool.
