Check
and,
if
necessary,
adjust
the
cutting
gap/clearance
of
the
channel
guide
The
press
body
(see
fig.
88)
is
guided
by
sliding
bearings
horizontally
and
vertically
in
the
press
channel.
The
height
of
the
press
body
can
be
adjusted
by
means
of
different
adjusting
screws..

screws
Experience
shows
that
wear
and
tear
of
the
bearing
is
very
low
and
there
is
thus
little
need
to
adjust
them.
During
the
2
‐
month's
running
‐
in
time
the
cutting
gap
should
be
checked
once
a
week.
After
the
running
‐
in
time
proceed
according
to
the
appropriate
interval
in
the
maintenance
schedule.
Observe
safety
conditions!
SWITCHING
OFF
&
SECURE
(see
7.1)
Failure
to
observe
this
notice
may
result
in
the
side
edges
of
the
press
body
and
those
of
the
channel
coming
into
contact.
This
results
in
score
groves
on
the
parts
which
touch.
The
functioning
and
service
life
of
machine
are
not
normally
affected
by
these.
However,
the
resulting
roughness
means
that
material
will
enter
this
gap.
7.4.16
Adjustment
press
body,
press
channel
and
cutting
gap:
check
and
adjust
if
necessary
A
correct
side
guide
is
very
important
otherwise
jams
will
occur.
The
cutting
gap
as
well
has
to
be
correctly
adjusted
otherwise
severe
damages
may
occur.
A
cutting
gap
of
less
than
1
mm
is
set
at
the
factory.
Ensure
that,
if
at
all
possible,
this
value
is
not
exceeded.
A
cutting
gap
which
is
too
large
or,
respectively,
blunt
knives
may
in
the
worst
possible
case
result
in
the
press
face
becoming
blocked.
A
too
big
cutting
clearance
(>2mm)
in
connection
with
blunt
cutting
edges
(edge
radius
>0,5mm)
and
appropriate
material
behaviour
(e.g.
foils,
PET
o.s.)
results
in
vertical
force
introductions
into
the
housing
structure
which
could
add
a
multiple
of
the
thrust
of
the
pressing
ram.
Thus
severe
damages
(cracks,
permanent
deformations)
can
be
caused.
