When the reverse roller solenoid [A] is turned off, the reverse roller [D] stops as the stop-
per [B] locks the clutch gear [C].
However, since the feed rollers [F] turn continuously, the master continues to be fed
causing the master to buckle. This buckle is detected by the master buckle sensor [E].
When the sensor turns on, the main motor turns on at 10 rpm to rotate the drum. The
main motor turns off when the sensor. turns off.
Therefore, the master is fed by ttie ON/OFF action of the master buckle sensor.
