The automatic strip tightener reduces the width of the film to one string
and reinforces binding of the product.
SINGLE AUTOMATIC STRIP TIGHTENER DOUBLE AUTOMATIC STRIP TIGHTENER
The device is made up of a frame (1) with a chain ring (2) controlled
by a gear motor (3) . The same frame has an idle roller (4) that forces
the film to follow a certain path; see diagram (A) . Attached to the chain
(2) is a grooved idle wheel (6) (or two in the case of a double strip
tightener).
Operating the gear motor (3) , the chain (2) moves the grooved idle
wheel (6) (or the two wheels in the case of the double strip tightener)
vertically. When it encounters the strip of stretch film, it reduces the
film width to a string.
The frame
(1) has two sensors:
- sensor (7) stops the grooved wheel (6) in the bottom position that
corresponds to the strip of stretch film reduced to a string.
- sensor (8) stops the grooved wheel (6) in the top position that
corresponds to the extended strip of stretch film.

Open the door and insert the film between the rollers following the
path indicated in figure (A) , the symbol with the triangles identifies the
side of the film to which the bonding agent (if present) is applied.
IMMAGINE SPECIFICA
Using the functions that can be set from the panel, the following is
possible:
- Exclude (F34=0) or include the device and choose the number of
rotations X at the base of the product (F34=X) .
- Exclude (F36=0) or include the device and choose the number of
rotations X at the top of the product (F36=X) .
- Exclude (F35=0) or include the device during carriage ascent ( F35=1
for the entire ascent, F35=2 up to the reinforcement* excluded,
F35=3 from the reinforcement to the upper rotations and F35=4
only during reinforcement*).
- Exclude (F37=0) or include the device (F37=1) during carriage
descent.
- Choose the final number of bottom rotations (F38=X) .
- Choose the reduction of the film strip, setting the adjustment time
(F39=X) .
- Enable the ascent of the carriage with the device included at the top
of the product after performing the upper rotations with film open
(F63=X) .
