4. Setting
the
fold
roll
gap/pressure.
Note:
The
proper
factory
calibration
of
the
gapsets
is
to
where
by
individually
pulling
on
each
strip
of
paper
and
the
fold
rolls
just
starting
to
rotate.
Not
enough
fold
roll
pressure
could
cause
the
folds
to
be
tight
and
not
provide
enough
drive
for
the
sheets
to
flow
through
the
roll
bank.
Too
much
fold
roll
pressure
can
cause
unnecessary
cracking,
especially
on
coated
stocks,
and
could
cause
premature
wear
of
the
fold
rolls.
a) To
do
this,
gently
pull
on
the
strip
of
paper
on
the
operator
side
and
feel
the
amount
of
pressure
the
fold
rolls
are
applying.
o
If
pulling
on
this
strip
of
paper
fells
like
there
is
not
enough
pressure
and
does
not
cause
the
fold
rolls
to
start
rotating,
turn
the
gapset
knob
counter-­‐clock
wise
to
add
more
fold
roll
pressure.
o If
pulling
on
this
strip
of
paper
fells
like
there
is
too
much
pressure
and
cause
the
strip
of
paper
to
tear
rotating,
turn
the
gapset
knob
clock
wise
to
reduce
the
amount
of
fold
roll
pressure.
b) After
feeling
the
pressure
on
the
strip
of
paper
on
the
operator
side,
gently
pull
on
the
strip
of
paper
on
the
non-­‐operator
side
and
feel
the
amount
of
pressure
the
fold
rolls
are
applying.
o If
pulling
on
this
strip
of
paper
fells
like
there
is
not
enough
pressure
and
does
not
cause
the
fold
rolls
to
start
rotating,
turn
the
gapset
knob
counter-­‐clock
wise
to
add
more
fold
roll
pressure.
o If
pulling
on
this
strip
of
paper
fells
like
there
is
too
much
pressure
and
cause
the
strip
of
paper
to
tear
rotating,
turn
the
gapset
knob
clock
wise
to
reduce
the
amount
of
fold
roll
pressure.
c) Now
that
you
have
initially
calibrated
the
fold
roll
pressures
on
the
operator
and
non-­‐operator
sides,
you
must
go
back
and
check
the
pressures
on
each
strip
of
paper
again
to
ensure
the
pressures
remained
the
same.
You
may
have
to
readjust
the
pressure
on
each
side
to
ensure
the
proper
amount
of
fold
roll
pressure
is
maintained.
