5.3. FILM WRAPPING TENSION
- ADJUSTMENT
1. Loosen nut (A) and rotate flange (B); by
turning clockwise the roller’s braking
effect increases therefore wrapping
tension.
Adjustment is very sensitive, therefore
turn the flange of just a few revolutions
to obtain the desired effect.
2. Once adjustment is performed,
completely tighten the bolt to avoid
loosening during rotation.
Important
Do not exceed with the braking effect.
Avoid an excessive wrapping tension.
5.4. GUIDE UNITS
ADJUSTMENT
The guide rollers must be adjusted
according to the product length.
1. loosen handle (A) and move the unit.
2. tighten handle.
3. Check that the guide rollers allow the
passage of the product without exerting
any thrust on it.
4. Furthermore, check that the infeed units
are aligned with those on outfeed to
avoid product jamming during
conveyment.
5.4.1.PNEUMATIC GUIDES ON ONE
SIDE
For guides with pneumatic operation on one
side only, adjust the units on the fixed side by
hand wheel.
Adjustment is not necessary for each product
width as the machine works correctly even with
products slightly decentred.
5.4.2.MANUAL SELF-CENTRING
GUIDES
In the self-centring units, adjustment is
performed by hand wheel, allowing positioning
of the guides on both sides.
