Method of accommodating photographic film with enlongated leader member in photographic-film cartridge

A method of accommodating a strip of photographic film in a main body of a photographic-film cartridge in a state in which a first end of an elongated leader ember provided separately from said strip of photographic film is mounted on a spool in said cartridge and a predetermined length of a second end of said elongated leader member extends out of said cartridge, said method comprising the following steps:

• a first step of inserting the leading end of a strip of photographic film into said main body of said cartridge through a photographic-film outlet defined in said cartridge such that said photographic film contacts said second end of said elongated leader member extending from said cartridge;
• a second step of rotating said spool and feeding said strip of photographic film into said main body of said cartridge with said leader member serving as a guide member for said photographic film, until a leading end of said strip of photographic film is held by successive convolutions of said leader member, or said leader member and said spool;
• and
• a third step of rotating said spool to wind said strip of photographic film onto said spool with the aid of frictional force produced when the leading end of said strip of photographic film is held between successive convolutions of said leader member, and another frictional force produced when said leading end of said strip of photographic film is held between said leader member and said spool, thereby accommodating said strip of photographic film in said main body of said cartridge.
