3. Paper flow and operating principle
3-1 Folding section
1．Papers loaded on the feed tray are separated to 1
sheet by the separator unit when being fed by the
paper feed ring.
(The timing for feeding the paper is controlled by the
PPS 1 which senses paper flow.)
2． In the double feed detecting section, the paper presses
up the upper double feed detection roller when it passes
between the rollers. When the upper roller is pressed
up higher than reference position, double feed is detected
and the machine stops.
(Error message ‘DOUBLE FEED’ will appear in the display.)
3．The paper passed through the double feed detection
section is fed to the folding tray 1 by the folding rollers
1 and 2, and stops at the stopper. The stopped paper
sags and is fed to the path between the folding rollers
2 and 3, and then is fed to the folding tray 2.

4．The paper fed to the folding tray 2 sags by bumping
the stopper as well as the flow in the folding tray 1,
and is fed to the path between the folding rollers 3
and 4, and then is fed to the sealer section by the
ejection roller.
(When V-fold is executed, the paper is fed directly
to the path between the folding rollers 3 and 4 from
the folding tray 1 by leading with the turn guide.)
3-2 Sealer section
1. The paper fed to the sealer section touches the stopper,
and is fed to the pressure roller section by the feed
rollers and roller.
2. The temporary sealed part in the folding section of the
paper fed is peeled off by the bracket F (upper and lower)
installed adjacent to the feed roller, and then is fed to the
pressure roller section.
3. The paper is applied by strong pressure between the
pressure rollers, and pressure sensitive adhesive
parts are adhered.
