Pile Feeder

The paper feeder is specially designed to feed
index stocks at high speeds. It is very important
for the operator to keep the feeder in good working
condition and to learn how to adjust and correct for
various operating conditions. The importance of
this is magnified by two conditions. First, the
machine is handling papers which have already
been through two or three other machines and,
because of this, may not be in pristine condition.
Second, the stocks being fed may vary, and will
vary greatly in feeding ability. Knowing how to
make fine adjustments to compensate for various
paper conditions will greatly increase the
productivity of this machine.
The most critical area in any paper feeder is at the
point where the vacuum nozzles contact the top
sheet to lift it from the stack. If papers and
operating conditions were uniform all of the time,
this would not present a problem. However, the
papers handled by this machine tend to have
various curls, warpage, ripples, etc., which greatly
hamper feeding. The sheets may tend to curl up or
down or the entire stack may be tilted due to
moisture from printing. The following "hints" will
help the operator to keep the Scott 10,000
operating at maximum production speeds.
3.3.2.1 Sheet Separator Fingers
The position and condition of the sheet separator
fingers should be carefully maintained. Each sheet
separator finger should be centered both top and
bottom and right to left of the mounting block
opening. Care should be taken to make certain
that the fingers are free and extend into the sheet
about 1/8--inch (6.3mm). Whenever the position of
nozzles is changed, the stack guide should be
moved until the finger is slightly to the left of the
nozzle.
The separator fInger should be 1/2"
above the paper stack.
