When
pressing
plastic
foils
a
minimal
cutting
gap
is
particularly
important.
Initial
pressures
of
approx.
100
bar
during
the
return
stroke
indicate
jamming
through
foil
which
is
taken
up
as
a
result
of
a
cutting
gap
which
is
too
large.
Blunt
knives
/
counter
blades
can
contribute
to
this
fault.
Observe
safety
conditions!
