The perfect interaction

­Truetzschler combing and draw frame technology

The introduction of the Comber TCO 12 has set

new technological standards.

Toyota's knowledge of the combing process

and experience with servo motors in weaving
machines was combined with the know-how in
the development of high-performance drafting
systems in spinning preparation.

The result: the Truetzschler TCO 12.

It stands for consistently highest and reproducible

qualities even at high production rates.

With the TCO 12A, fully automatic operation

in combing is possible for the first time.

The robust
­Truetzschler drafting
system with pressure
bar was designed for
the high sliver masses
and drafts of the
comber.

of larger, and thus more economical can formats up to
1,200 mm diameter.

In a combing mill, the JUMBO CANS can be applied
between card and breaker draw frame, breaker draw
frame and Superlap, and between comber and auto­
leveller draw frame.
A spinning mill with an annual production of 6,000 t
requires approx. 840,000 can transports per year
when using 600 mm cans. This, of course, means
the same amount of sliver piecings. In a spinning mill
with 1,200 mm JUMBO CANS, the can transports
and sliver piecings are reduced to approx. 240,000.

Can changers above or under floor

The under floor version simplifies handling particu-
larly when large cans are used. The cans can easily
be inserted into and removed from the can changer.
As is common with other combers, no step must be
overcome.

To ensure that the full potential of the space-saving

reliable pneumatics.

The ­Truetzschler TWIN Draw Frame TD 9T in the typical ­Truetzschler design is the space-saving

Multi-drive technology

The Superlap produces premium quality laps with its multi-drive

technology, consisting of four individually controllable and
maintenance-free direct drives.

Fastest lap change time - increased productivity

Lap change times of less than 20 seconds are only
possible due to the individual drive technology and a
clever tube change system.
The empty tube on the TSL is inserted laterally at the
same position where it is wound shortly after.
At up to 600 lap changes per day, this means a 15%
increase in productivity at the same settings.

Individual drives make an optimization of the lap build-up possible. Influence of lap change time

Thanks to this technology, important process param-

eters such as drafts, tensions and lap pressure can
be adjusted during lap build-up. Thus, the lap separa-
tion can be implemented directly by the drives; there
is no need for complex mechanisms prone to failure. 15% less production

This results in premium quality laps due to uniform

30 Combing / TCO 12 – Lap transport

Meaningful automation
The automatic lap transport system for the TCO 12

Developed in cooperation with Neunhauser, the spe-

cialist for automated spinning mill transport systems,
the automated lap transport in combing is one of the
most meaningful investments. In addition to person-
nel cost savings compared to manual lap transport,
even more benefits become apparent in practice:

Clarity
Since the entire transport is performed overhead,
the aisles remain unobstructed. There are no emp-
ty lap tubes or transport carriages in the way. The
floors are easy to clean.

Controlled material flow

An automatic lap transport system brings the lap to
the exact comber where it is needed next. No comb-
er is down because a lap is missing, even during a
night shift with reduced personnel.

Quality gain
Since the laps are not touched by the operators, the
outer layer of the batt remains as perfect as when
leaving the Superlap. During manual transport, the
very sensitive outer layer of the lap can easily be
damaged when touched.

An automation system can

connect a Superlap and up to 6
combers with a transport system.

The new generation finisher draw frames:

Truetzschler TD 10-600 
A draw frame especially for combed yarns

As a quality filter of the spinning mill, the finisher draw frames

has an important function: Preventing errors in the sliver which
inevitably lead to yarn defects. Because quality can no longer
be improved after the finisher draw frame.

The new compactness

The new TD 10 is 14 % shorter, because length
matters. Thus, compared to competition, the space
savings averaged over all can heights are more than
20%.
This means that savings of up to $ 17,200 can be
realised by a spinning mill with an output of 1000 kg
per hour.

SMART CREEL

Most energy efficient suction system worldwide

The TD 10 only needs 800 m³/h suction at a negative
pressure of -450 Pa. Compared with the competitor
this means 30 % less exhaust air.
This leads to up to 6300 € less energy costs for the
SMART CREEL – intelligent single sliver detection filter of the central suction system per year.*
The SMART CREEL detects whether a sliver is exis-
ting and additionally whether it moves. This makes a

In contrast to contact switches, the optical sensors
are safe against operating errors because they also
