Placing film rolls

5.3.1

Auto-grip shafts

Both shafts in the front of the machine are the same. The shafts fit into the machine in both
ways. Their function is determined by their position in the machine and the setting of the
tension control.
The shafts on the rear side can swing out of their support on the control panel side.
On the other side the shaft is fixed to the machine.
On the control panel side of the machine all the shafts and the supports snap together by a
gripper slot and gripper.
A spring inside the left-hand side support pushes the shaft into locking position when the
shaft is turned. To position the shaft correctly push it firmly into the supports and turn the
shaft until it locks in.
Check the auto-grip mechanism on each shaft. The rubber cords should just touch the
edges of the recess (Figure 13A: d = 8 ± 2.5 mm).
If not, see chapter 6 Maintenance.
Figure 13: Auto-grip shaft
When the shaft is rotated inside a cylinder, the rubber cord will move to the side and gets
caught between shaft and cylinder (Figure 13B). Rotating back will release the cord.
5.3.2

Use of films with release liner

When using a film with a release liner that must be removed, load the wind-up shaft with a
scrap core (empty cardboard cylinder) of (at least) the same width as the film.
1. Take the auto-grip shaft from the wind-up position of the machine.
2. Place the scrap core on the shaft, holding the shaft as in Figure 13C.
CAUTION:
Do not drop the end of the shaft on the floor.
3. Put the shaft with cylinder back into the machine.
4. Push both sides of the shaft firmly into their supports.
5. Turn the shaft until the grippers lock in.
