Spread/Feed Function Check
Use a sheet or similar piece of flatwork to
test the feeder. Press a STATION button to
select a program. Stand clear of all moving
parts and watch for the following:
The piece is carried upward by the
input conveyor (Figure 2-31) to the
transfer point.
The transfer clamp, located at the cen
-
ter of the unit (Figure 2-32), moves for-
ward and grabs the flatwork as close as
1-1½” from the corners, where it is held
for the spreader clamps to grab it.
The spreader clamps (Figure 2-33) and
lower spreader belts spread and smooth
the flatwork.
The laydown air blast occurs (Figure
2-34) and the piece is smoothed by the
doffer rolls as it travels on the discharge
ribbons.
Turn power OFF at the main disconnect
switch. The Start/Stop button lamp and the
CHI panel display will go out.
Each photosensor on the unit is physically
aligned and sensitivity adjusted for testing
purposes before shipment.

Different environments require alignment
and sensitivity adjustments during instal
-
lation to ensure reliable operation of the
sensors. Sensors that are misaligned or out
of adjustment can miss a piece of flatwork
or give a false signal when no material is
there. For more information, refer to the
REPAIR chapter,
Sensors
section.
