ith ITMA Asia + CITME 2010 coming in June, spinning and twisting machinery manufacturers
will be introducing new technologies for both the Asian and overall global markets. Following is a
sampling from four suppliers.
Trützschler Spinning and Trützschler Card Clothing (TCC), two of three businesses comprising
Germany-based Trützschler GmbH & Co. KG, provide technology and machinery for spinning
Trützschler Spinning is putting emphasis on its foreign parts detection and separation
technology. The top-of-the-line Securoprop SP-FPU detects foreign parts – including colored,
transparent and partially transparent parts – using polarized light, and is particularly effective
for detecting materials such as polypropylene or polyethylene foil, which – though similar to
cotton in color – are not detected by conventional foreign part separators.
TCC reports its new FGX1 cylinder card clothing for spinning noticeably improves the quality
of combed yarns, even when installed on older cards and with lower production rates than are
achieved using newer cards. The company also notes that the clothing lasts up to 30-percent longer
than earlier varieties and requires half the maintenance.
The FGX1 cylinder wire features a new tooth shape and offers a soft carding process. It also
reduces imperfection indicator (IPI) values by 15 percent, and reduces neps by up to 90 percent.
Rieter Machine Works Ltd., Switzerland, is promoting its RSB-D 22 double-head autoleveler
draw frame and its new G 32 ring-spinning machine. Edda Walraf, the company’s head of marketing,
reports both machines are designed to provide high- and consistent-quality short-staple yarns made
of 100-percent cotton, man-made fiber and blends of the two.
The RSB-D 22, with 2 x 1,100-meters-per-minute (m/min) maximum delivery speed, and RSB-D 22c
for combed cotton, with 2 x 550-m/min maximum speed, feature two completely independent machine
sides and autoleveling functions, with quality and output of each head comparable to that of
Rieter’s RSB-D 40 single-head draw frame. Advantages of the double-head model include reduced space
requirements, low energy consumption owing to joint utilization of one extraction fan for both
heads, and reduced capital cost. The independent machine sides also improve efficiency by 10 to 15
percent over conventional double-head draw frames and produce superior sliver quality as there is
no coupled delivery roller drive as is typical on other draw frames, Walraf said. Flexibility is
enhanced because each machine side can be set for different sliver weights and speeds. Space-saving
features include machine widths of 320 centimeters (cm) for the RSB-D 22 and 290 cm for the RSB-D
22c; and the option of setting the machine into the floor, which reduces its length by 1 meter or
so. Also, large sliver feed cans can be arranged in three rows instead of two to reduce roller feed
The G 32 features up to 1,440 spindles, reducing investment costs per spindle. Other
features include: Rieter’s Ri-Q-Draft drafting system, which, according to Rieter, improves yarn
quality owing to effective fiber guidance and spinning geometry; ROBOdoff offering short doffing
cycles and operating in combination with SERVOdisc cops and tube transport and handling system; and
SERVOgrip to eliminate underwound threads and reduce fiber fly. The machine also offers flexibility
to adapt twist and yarn feed from the control panel. Additional programming from the control panel
can reduce doffing ends down, and optimized speed curves minimize spinning ends down. Machines with
more than 1,200 spindles offer a FLEXIstart option to start the machine in two halves.
Rieter’s RSB-D 22 double-head autoleveler draw frame saves space as well as associated
costs and features a maximum delivery speed of 2 x 1,100 meters per minute.
Germany-based Oerlikon Textile GmbH & Co. KG’s Oerlikon Schlafhorst business unit offers
several new rotor- and ring-spinning and winding technologies.
The BD 416 rotor-spinning machine, the latest generation of the company’s BD series, has up
to 416 spinning units and an electronically controlled high-precision drive system. The company
reports that, with its high take-up speed, the machine’s productivity surpasses that of comparable
rotor-spinning machines; and that it takes up less space than comparable machines despite the fact
that it has more spinning units.
The Zinser 351 Impact FX compact ring-spinning machine features up to 1,680 spindles, making
it the longest compact spinning machine made and optimizing cost and space efficiencies, Oerlikon
Schlafhorst reports. Efficiency also is enhanced by the machine’s independently adjustable vacuum
unit that is detached from the yarn breakage suction; automatic self-cleaning, facilitated by the
apron design and material choice for the unit; and straight airflow through the system, which
eliminates clogging from particles being caught in corners or bends. The machine can process all
fiber types and blends, with settings for different fibers managed using the EasySpin touchscreen.
Oerlikon Schlafhorst’s new Autoconer X5 winder features enhanced automation and flexibility.
The company reports customers may use either traditional drum-winding systems, or drumless systems
with PreciFX using Speedster FX to raise productivity and/or yarn quality. The winder also features
a new X-Change doffer with expanded functionality, flexibility and speed; Plug&Wind and CAN bus
technology; simplified operation; and low energy consumption.
Italy-based Savio — doing business as Savio Macchine Tessili S.p.A. and comprising the
spinning brand of Itema Group’s Itema Spinning subsidiary — is promoting the Polar I/DLS (direct
link system), the newest model in its Polar line of automatic link winders, which are available in
a range of configurations with up to 72 drums. The company, which first introduced its Polar
winders in 2006 to meet the needs of spinners in the Far East, reports the new model offers
affordability and simple but sophisticated operation for an industry that is becoming increasingly
Savio’s Polar I/DLS link winder features a modular, high- efficiency bobbin processing
The Polar I/DLS features an innovative closed-loop spinning frame-to-winder feeding system
that allows materials to move completely freely through the system, according to Savio. No hands
touch the yarn as it is processed from the speed frame bobbin to the final package, thereby
reducing material handling and eliminating possibilities of contamination while maximizing quality.
The winder also features a modular, high-efficiency bobbin processing system; and the spindle now
has a straightened yarn path, with two additional bobbins lined up ready for winding at each
spindle. The suction unit is driven by a high-efficiency inverter, minimizing energy consumption,
and a fully integrated, self-adjusting suction management system creates optimal suction based on
the machine’s actual requirements. This feature, coupled with the spindle’s Flexycycle, minimizes
hard waste, Savio reports.
Other features of the Polar I/DLS include: electronic anti-patterning device for improved
package formation; computer-aided tension to equalize yarn tension on the package; and
computer-aided metering to minimize metering differences and equalize package density.
