5.3 Placing film rolls
5.3.1 Auto-grip shafts
All shafts are the same. Their function is determined by their position in the machine.
The shafts fit into the machine in both ways.
On the control panel side of the machine the shaft and the suspension snap together by a
gripper slot and gripper.
At the left-hand side of the machine the shaft has a thrust piece in the suspension. This
thrust piece pushes the shaft into locking position when the shaft is turned.
To position the shaft correctly push it firmly into the suspensions 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 15A: d = 8 ± 2.5 mm).
If not, see chapter 6 Maintenance.
Figure 15: 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 15B). 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 16.
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 suspensions.
5. Turn the shaft until the grippers lock in.
