4.3 SET FILM PRE-STRETCH
Use the gear control (see the gure on the left) directly above the roll
of lm to set different degrees of försträckningsgrader.
According to the Cyklop philosophy:
100% pre-stretch=1 metre lm on the roll will be 2 metres on the pallet.
200%: 1 metre will be 3 metres, 300%: 1 metre will be 4 metres,
and so forth. (The lm tension value also makes a difference.)
GL 205, GL205 HS
Gear 1= 1%
Gear 2= 25%
Gear 3= 45%
Gear 4= 65%
Gear 5= 90%
Gear 6= 135%
Gear 7= 170%
Gear 8= 210% GL 215, GL 215 HS
Gear 1= 30%
Gear 2= 60%
Gear 3= 80%
Gear 4= 110%
Gear 5= 145%
Gear 6= 200%
Gear 7= 250%
Gear 8= 300%
If you select a high gear, the lm will be thinner on the pallet goods.
This means lower lm cost, but it also requires a higher lm quality
than a lower gear. Start with gear 6, for example, to see whether the
lm holds. If it breaks, switch to a lower gear or a higher lm quality.
The machine is equipped with a semi-automated, electronic
system for optimizing lm tension between the aggregate and
the goods.
To use the machine in the best way with different lm types
and goods the tension have to be set manually. If not, pro-
blems may occur with the output of lm. Either the lm roll may
eject the lm intermittently and annoying sounds may occur or
that the good may be exposed to too high tension.
Adjust the tension by turning the potentiometer for lm ten-
sion.
INCREASE Turn the potentiometer clockwise
REDUCE Turn potentiometer counterclockwise
Remember that if too high lm tesion is set, the lm might
break.
Setting the lm tension when wrapping fragile items:
1. Start lm cycle
2. Reduce the lm tension slowly until the lm is ejected in-
termittently.
3. Increase by one unit on the scale
Setting up the lm tension when wrapping non fragile items:
1. Start lm cycle
2. Increase the lm tension solwly until the lm is close to
breaking, or that the goods will be wrapped too tight.
3. Turn down one unit on the scale.
The system allows for this adjustment, the best results both
economically and packaging technology.
Example, settings Loose lm tension Tight lm tension
Cast lm 17-20 my
Blown lm 20-25 my
