MASTER FEED
C249 6-24 SM
Procedure
The duct plate [A] is in the middle position before printing. (1)
↓
The duct plate moves to the close position when the master is fed until the master
tension roller [B] catches the leading edge of the master. (2)
↓
Clamper [C] opens. (The drum is at the master feed position.) (3)
↓
The duct plate moves to the open position when the clamper clamps the master. At
this time, the master is stored in the master buffer duct [D]. (4)
↓
The duct plate moves the master push mylar [E] after the clamper clamps the
master. At this time, the master push mylar contacts with the master on the drum
(5). The master push mylar prevents air pockets and distributes the ink through the
master as the master is wrapped around the drum.
↓
The cutter [F] cuts the master after the master is wrapped around the drum (6).
