Sheets are fed.
- The feed roller rotates and feeds sheet one by one
to the buckle chute. (Fig. 1)
The sheet hits the stopper.
- The sheet hits the stopper on the 1st buckle chute
and stops. (Fig. 2)
The sheet is bent slightly.
- The sheet stopped by the stopper is bent, and the
fold rollers catch the sheet bend. (Fig. 3)
- When the folding speed is set to “High”, the amount of
sheet bend is slightly changed. Set the stopper posi-
tion 1 mm (0.04”) shorter than the normal setting.
- When the heavier sheet is folded, the amount of sheet
bent becomes smaller. Set the folding speed to “High”
to create bigger sheet bend.
The sheet is folded.
- The fold rollers catch the bending part of sheet
and sheet is folded.
- The fold position changes depending on the stop-
per position.

The feed roller rotates to the

The rotation of the clutch stopper
stops when the clutch lever lowers.
The clutch spring istwisted to
the arrow direction, and the inner
diameter of the clutch spring isenlarged.
Since the inner diameter of the
clutch spring isenlarged, the power
transmission to the feed roller shaft is
shut off, and the clutch bushing is
slipped on the clutch pulley.
The feed roller does not rotate although
