11 Feedroll Gap
Function
This is the gap between the roll contact surfaces.
DO NOT
allow
the upper roll and lower roll to contact one another for an
extended period. If the rolls are touching, turn off the machine
immediately and adjust the feedroll gap. Operating the machine
with the rolls in contact will rapidly erode the knurling on the
rolls, reducing material feeding efficiency.
Step 1 Lockout/tag out power.
Step 2 Unbolt the guard and remove from machine.
Step 3
Loosen the adjustment screw jam nut located on the
right hand
side of the feedworks.
Step 4
Turn the screw counterclockwise (
Figures 8a, 8b and 8c
) to
lower the upper feed roll until it contacts the lower feedroll.
Step 5
Now turn the screws in the clockwise direction to raise the upper
feedroll until a .010” gap is achieved between the two rolls.
Step 6
Tighten down the jam nut while holding the adjustment screw
stationary.
12 Material Guide Gap
Function
The Material Guides prevent material from feeding around the
roll and tangling. They are located behind the upper and lower
feedrolls. A small gap must be maintained between the guides
and the rolls. The gap needs to be at most, ½ the thickness of
the thinnest material being fed into the machine. The gap will
widen over time as the knurling on the feedroll wears down and
will require the material guide gap to be adjusted.
Step 1 Lockout/tag out power.
Step 2 Unbolt the guard and remove from machine.
Step 3
Lift chain off sprockets by first depressing the chain tensioning
arm (
Fig. 3
).
Step 4
Remove the bolts holding the lid in place and slide forward to
remove. Rotate the upper feedworks assembly forward.
Step 5
The upper and lower material guides are each fastened with two
screws. Loosen the screws holding the guide in place and adjust
the gaps to half the thickness of the thinnest material being
processed. Use a feeler gauge to verify the gap.
Step 6
Once gap
is achieved, tighten the screw
s
. Double check the
gaps and rotate the feedrolls to make sure the material guides
do not contact the feedrolls.
