STEP 6:
Manual Test
to Verify
Now that you have made all the necessary adjustments for operation,
it is recommended that you verify material singulation and separation
at the feeder for your particular application. Before you power-up and
run your machine with a full hopper, manually feed several sheets of
material through the gate assembly area.
Prepare your test by loading the hopper with approximately 2 to 2.5
in. (5 to 6 cm) of material. Make sure you preshingle the stack so that
material rests against the curvature of the gate assembly.
1. Manually feed several sheets of material slowly through the
gate assembly area. Move the drive belts by pressing your
thumb against the discharge belt.
2. Observe how individual material enters and exits the gate
assembly area. Remember, a properly set gap will allow each
new sheet to enter at about the center line of the cylinder
while the bottom sheet is exiting the gate assembly area
(Figure 2-16). Ideally, this means a slight overlap of both the
first sheet and the second sheet (.125 in., or 3 mm) at the gate
assembly area. The overlap occurs as the bottom sheet is
exiting and the next sheet is entering.
3. If feeding doubles, move the wedge in toward the gate
assembly. Test again.
4. If sheets are overlapping excessively or, if the machine is
feeding doubles, reduce the gap slightly by moving the knob
about 1/8 turn counterclockwise. Test again.
5. As material moves through the hold-down area, check for any
skewing or jamming. Also check for damage to the material.
6. If this or other feeding problems still persist (slipping,
skewing, jamming), then review all the adjustment procedures
in Section 2, Preparing for Operation.
If the gate assembly is too tight, the feeder will
have difficulty pulling the material through the
gate assembly area. This will cause “missed”
feeds.
NOTE
Figure 2-16. Optimum Overlap and Separation of Material
NOTE
Moving the back wedge too far forward to the
gate assembly can create a pinch point between
the tip of the triangle wedges and the material. If
moving the back wedge in is not effective, then an
optional wedge may be required. See Section 6,
Additional Wedges, for more information.
TIP
For certain types of materials, you may have to
position the material “off-center” to prevent any
skewing affect.
