
The sleeving material, referred to as film, is actually a continuous tube which has been laid
flat and wound onto a core to form a reel.

Before the film is cut to form a sleeve, it must be opened into a
more circular shape. To achieve this a film Material Spreader
Mandrel like the one shown in the left is used. Each mandrel is
manufactured to suit a particular size of film.

The layflat size of the film relevant to each spreader is marked
on one of its fins. Select the correct size spreader for the film
being used and insert it into the film a distance of approximately
150mm.

Once the film is inserted into the mandrel, it is supported by
adjustable mandrel support, material feed driver and applicating
driver. To secure the mandrel, make sure all support rollers on
each part are tightened properly.

Once the mandrel is secured properly, the mandrel should not
be able to be moved by hand, if there is movement, check all
support roller and drivers.

Once passing the mandrel, the film will be expanded and fed
through, getting ready for the cutting set.
