14. The register is supplied with 2 short
sheet holddowns and 1 long sheet holddown. The 2
short holddowns should always be used. They are
placed in front of the sucker wheel guard assembly
on the angle braces above the register ribs. The
long holddown is used on sheets that require the
register gage to be beyond the end of the sucker
wheel guard assembly.
15. The pile feeder and register has a
double sheet detector designed to stop double
sheets from being fed onto the register and being
folded. This allows the double sheet to be stopped
at the double sheet detector and be removed
while the previously fed sheets are folded without
interruption. This will also shut off the vacuum
to the sucker wheel, preventing more sheets from
being fed until the double sheet is cleared.
The double sheet detector’s main
functional components are the sensing cam, roller
bearing and proximity sensor. When a single
sheet is ran through the double sheet detector,
the sheet will pass between the sensing cam, and
roller bearing without any drag, thus the sensing
cam will not move. If the sensing cam does not
move, the proximity sensor will continue to see
the sensing cam, and the pile feeder will continue
feeding sheets.
If two or more sheets are fed by the pile
feeder, this will cause the sensing cam to rotate
in the direction of the paper travel. As the sensing
cam rotates, the gap between the sensing cam and
roller bearing will close up, and actually pinch
the sheets. As the sensing cam rotates, the gap
between the sensing cam and roller bearing will
close up, eventually pinching the multiple sheets.
This will cause the sheets to stop immediately
from traveling further on the register, and the
proximity sensor will no longer sense the sensing
cam. This will cause the pile feeder operator
control panel to display “DOUBLE SHEET”. A
double sheet error on the pile feeder will prevent
sheets from being fed by the sucker wheel until the
double sheet error is cleared.
The double sheet detector must be set up
so that the sensing cam remains untouched when
a single sheet of paper is passed through. It also
must be set up so that when 2 or more sheets of
paper are fed
The double sheet detector will now only
allow one sheet thickness to pass through, and stop
multiple thicknesses from passing through.
The double sheet detector will need to have
this set up done for every job in which the stock
changes.
16. The pile feeder is equipped with an
adjustable blow bar for different stock types and
sizes. This blow bar is located on the pile feeder
below the sucker wheel guard assembly. The blow
bar has 5 different settings to change the number
of locations in which the blow bar allows air to be
blown into the pile for sheet seperation. The blow
bar is also designed to pivot, to allow air to blown
into the proper position on the stack to allow for
proper sheet seperation.
To set up the blow bar follow these
instructions:
through, the cam must be pushed in the direction
of the paper travel. This setup is acheived by doing
the following:
A. Tear two 0.75” (19.05mm) strips of the
paper to be folded.
B. Lift the lever of the double sheet
detector up.
C. Place the two strips of paper in between
the lever and the stationary block.
D. Gently pull on the strips of paper to
be sure that they are being held by the
