Tying
material
As
the
press
process
starts,
tying
material
(wire)
from
several
reels
is
fed
on
the
front
side
of
the
bale
that
is
forming.
As
the
bale
grows
both
in
volume
and
in
length
tying
material
is
pulled
over
and
underneath
the
bale.

the
bale.
Wire
cabinets
for
feeding

the
tying
material
are
foreseen
for
the
machine.
Optionally
