3.3.1.2 STRIP CUT
The strip cutting device can cut the film in 3, 4, or 5 strips, used to
stabilize products that need air (e.g., flowers, fruit, etc.) using a common
stretch film.
The frame
(1) has 2, 3, or 4 blades (2) that cut the film in the position of
the convex wheels (3) that keep the stretch film strips separated.

Using the functions that can be set from the control panel, it is possible
to configure the wrapping cycle as follows:
F55 include (F55=1) or exclude (F55=0) strip cutting.
F56 delay insertion of the cut (F56=X seconds) at machine startup to
being with an whole strip of film.
F57 and F58 control the cut at the top of the product and exactly:
F57 delays the insertion of the cut ( F57 = X seconds) in descent
startup if it was excluded with F58 = 0 .
F58 includes ( F58 = 1 ) or excludes ( F58 = 0 ) strip cutting during
execution of the top reinforcement rotations.
F59 stops cutting during ascent and shutdown:
- ascending, an amount of time ( F59 = X seconds) after reaching the
top of the product, cutting is disabled to move on to the entire strip.
- during shutdown, an amount of time ( F59 = X seconds) after the
rotation starts to slow down, cutting is disabled, allowing the last
segment of stretch film to exit unsectioned from the pre-stretch
carriage for easier control.
If you want to wrap the top part of the product by overflowing the film
beyond the top of the product itself, it is recommended to do so with
the stretch film not cut into strips, the stretch film must be one entire
strip; so, set F58 = 0 and F57 = X.
If, on the other hand, you do not want to overflow the top, it is also
possible to cut the film into strips during the reinforcement rotations
at the top, including cutting during this phase ( F58 = 1 ).
WARNING
The optional AUTOMATIC CUTTER and STRIP CUTTER cannot be
installed on the machine at the same time; one installation
excludes the other.
