Vacuum Feed Sheet Separator
The sheet separator will need adjusting for the
weight of paper you are bursting. Ideal adjustment
will feed only one sheet without marking the paper
or feeding doubles. Use the following procedure to
get started. (Fine tune these adjustments according
to the condition of the paper and the environmental
conditions of your particular work area.)
Adjustment Procedure
1. Raise the separator (ccw) (Fig. 16) to avoid marking
the sucker wheel. NOTE: Do not make separator
adjustments while the burster is running.
Squaring Feed Table
In order for your machine to burst properly the forms
must be fed into the rollers square. The feed table
is adjusted at the factory and should only require
periodic checks. The unique feed table adjustment
feature allows for quick and easy adjustment if
needed.
1. Adjust the feed table squaring screw and align the
center line of the scale with the center mark on the
feeder table (Fig 14).
2. Loosely position the feed table side guides to the
scales on the feed table, (Fig 14 & 15). Read the front
scale at the inside edge of the side guide clamp block.
The rear scale will line up with the inside edge of the
side guide. The scales are set up to center the paper
on the sucker wheel. Initially set each guide 1/4”
(6.4mm) wide. Do not tighten the lock knobs.
3. Raise the sheet separator counter clockwise (ccw)
so it is away from the sucker wheel (Fig 16). Place
a sheet of the paper to be folded on the feed table.
Slide the sheet forward into the rollers. The sheet
must contact the rollers evenly and not touch the side
guides. Turn Burster and blower on and press the jog
button to feed in approx. 1/2” (12.7mm) of the form
into the rollers.
4. Position the operator side guide so it is just touching
the sheet but not pushing it. The side guide must be
even to the sheet from end to end. Tighten the front
lock knobs then the rear knobs, (Fig 14 & 15).
5. Repeat step 4 on the non operator side guide.
6. The paper will now feed square into the rollers.
Now that the side guides are square, the feed table
squaring screw, (Fig 14), can be adjusted for fi ne
tuning the overall squareness.
