6.6.4 WRAPPING THE MASTER AROUND THE DRUM
Drum Lock and Master Clamper Open
The drum guide [A] holds the drum at the master eject and the master making
positions.
When the drum reaches the master making position, the drum guide moves to
engage the stud [B] on the rear drum flange until the clamper open position sensor
[C] is actuated. (The other stud was used for the master eject position.)
The master clamper opening arm [D] is just above the drum guide. The arm is
different from the one used for opening the master clamper at the master eject
position. The clamper motor [E] drives the arm and opens the master clamper [F],
in synchronization with the drum guide movement.
The drum guide moves (to open the master clamper) until the clamper open
position sensor is interrupted by the feeler. Then it stops immediately (unlike at the
master eject position of the drum) as shown in the diagram.
Before the drum starts turning to start wrapping the master on the drum, the drum
guide returns to the home position until the clamper close position sensor [G] is
activated. The master clamper opening arm also returns, closing the master
clamper.
CAUTION: Do not use alcohol to clean the magnet of the master clamper.
