of the reel or the film.

Typically, if the end of a strip of film is merely inserted
within a slot located on the hub of a reel, the film can
easily fall out, Alternatively, if a mechanical device is
used for holding the end portion of the film onto the reel,
the film eventually brakes with fatigue and flexing. It has
been found that these problems can be avoided by securing a
polyester tape 2, that includes an adhesive 7 on one side
thereof, to the end portion of a film 1 and around a pin 3,
preferably made of plastic, leaving a gap 6 between the pin 3
and the end of the film 1, as clearly shown in Figure 1 and
2. The polyester tape 2 is preferably secured to both faces
of the film 1, as shown in Figures 1 and 3. It is preferred
to use a polyester tape having a width slightly less than the
width of the film so as to prevent excess friction when the
reel is in use.

In operational use, pin 3 is inserted within the slot typi-
cally located on the hub 5 of a standar...
