in the master attach position, the master
feed clutch comes on, so that sponge roller2 is
driven and feeds out the master by a fixed
amount.
2) The master clamp opens and closes, to clamp the
master.
3) When the master is wound onto the drum, the
master feed clutch turns off, leaving sponge
roller2 free to be turned by the master as it is
wound off the drum.
(6) Master Feed Clutch(Electromagnetic clutch)
Description
Sponge roller2 is attached to the bottom section of the master conveyance way of the master feed unit, and is
driven via the master feed clutch (CL1) by the platemaking motor. The rotation of sponge roller2 is controlled
with the master feed clutch ON / OFF.
