The new spinning unit of the J
20 ensures higher yarn strength
and fewer imperfections. The im-
proved yarn quality also results
in a lower number of quality cuts
and natural ends down. Together
with the reliable robots of the J
20, far greater production ef-
ficiency is achieved, resulting in
high yarn production.
Due to the increased spinning
stability with fewer quality cuts, it
was possible to lengthen the J 20
by one section to a total of 120
highly productive spinning po-
sitions. The J 20 is therefore the
longest air-spinning machine
worldwide. Four robots, two on
each side, ensure maximum pro-
duction efficiency. The option of
separate sides makes the machine
even more flexible, allowing two
different yarn qualities to be pro-
duced simultaneously.
A further improvement realized
with the J 20 is the optimized ma-
chine construction. The centrally-
driven ventilators, the entire elec-
tric and electronic systems as well
as the supply and disposal con-
nections are integrated in the drive
frame. Separate filter chambers
process the waste from the spin-
ning positions, as also the waste
from the robots.
The bobbin delivery on the drive
frame has been lowered to a
height of 1.45 metres. This ena-
bles the bobbin conveyor belt to be
optimally controlled by the opera-
tor and the bobbins conveniently
removed and placed on pallets.
The end section only consists of
the service area for the robot at the
rear and the free-standing tube
feeder with an extended capacity
of 350 empty tubes. The two sepa-
rate tube chains, which allow dif-
ferent color tubes to be fed to the
left and right machine sides, are
a new feature of the tube feeder.
This prevents tubes being mixed
up when two yarn qualities are be-
ing simultaneously produced.
