5.3.1 Auto-grip shafts
All auto-grip shafts operate in the same fashion. Their function is determined by their
position in the machine.
The drop in shafts fit into the machine in either direction.
On the control panel side of the machine the auto-grip shaft gripper snaps into the brake or
clutch gripper slot in the shaft holder.
At the left-hand side of the machine the drop in shafts have a spring loaded plunger in the
shaft holder. This plunger pushes the gripper into the gripper slot (and into the locking
position) when the shaft is turned.
To position the shaft correctly, push it firmly into the shaft holders 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 (14A: d = .3” ±.1” [8 ± 2.5 mm]).
If not, see chapter 6 (maintenance).
Figure 14: Auto-grip shaft
When the shaft is rotated inside a film core, the rubber cord will move to the side and gets
caught between shaft and film core (Figure B). 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.
a. Take the auto-grip shaft from the wind-up position of the machine.
b. Place the scrap core on the shaft.
CAUTION:
Do not drop the end of the shaft on the floor.
c. Put the shaft with cylinder back into the machine.
d. Push both sides of the shaft firmly into the shaft holders.
e. Turn the shaft until the grippers lock in.
