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.
NO TE
STEP 3:
Back Wedge
Adjustment
Procedure
To adjust the back wedge for initial proper positioning, follow these
steps:
1. Grasp a handful of material, approximately 2 to 2.5 in. (5 to 6
cm) thick, and preshingle the edges with your thumb.
2. Place the preshingled material in the hopper so that the edges
rest against the curvature of the gate assembly.
3. Turn the back wedge wing-nut adjustment counter-clockwise
to loosen the wedge.
4. Move the back wedge forwards and backwards until the bot -
tom sheet is not touching the table top. A good starting point
is to measure about .625 in. (16 mm) from the bottom sheet to
front edge of table top. Then as you test, you can “fine tune”
from this point.
5. Make sure the edge of the back wedge assembly is parallel
with the edge of the material stack. Adjust as required and
then tighten wing-nut.
6. Check that individual wedges are evenly spaced to provide
enough support to lift the material off the table top and feed
belts, without any bowing or twisting.
Keep in mind that the back wedge works with
the gate assembly to provide the proper lift,
curvature of the material, and proper belt/
material contact to separate and feed one sheet
at a time.
NO TE
There are a number of feeding problems which
can be solved by simply adjusting the back wedge
to different positions. Some of these problems
include double feeds, skewing, twisting, poor
singulation, ink or varnish buildup on the belts,
and jamming at the gate assembly area.
