Rieter presented all four end spinning systems

For the first time in history Rieter presented all 4 end spinning machines from one source: ring spinning, compact spinning, rotor spinning and the new air-jet spinning technology. The principle of the 4 end spinning machines was exhibited in the form of models, screen shows, yarns and end products. Rieter specialists and their agent Erbel were present to explain in detail the difference between the 4 spinning technologies and the resulting yarn quality.

Four end spinning systems              

Rieter provides advice, which spinning system is the most suitable for the individual customer requirements. To compare the economic aspects of all 4 spinning systems, customers benefit from spin plan and pay back calculations for the whole spinning mill. The optimization of the fiber and sliver preparation process has a big impact on the machine performance and yarn quality. This aspect was again clearly visible during the market introduction of the new J 10 air-jet spinning machine.

Rieter is the only supplier offering machines for the complete spinning mill, they are able to analyze and optimize the spinning process over all process steps. This unique technology know-how from one source is available for all 4 spinning systems.

New J 10 air-jet spinning machine

The newly developed J 10 air-jet spinning machine presents an innovative technology that is also based on Rieter’s leading and proven know-how in the area of drafting and automation.

J10´s modular and double-sided machine concept provides for the top level of production flexibility. The unique quality features of the ComforJet® yarn manifest benefits for spinners, for down-stream processing and for final end-users. High speed features in yarn delivery and winding put this machine at the top of the productivity rate scale.

Leading features are:

• The J 10 comprehensive high-speed concept with individually driven winding system allows delivery speeds of up to 450 m/min.
• The unique sliver traversing system reduces wear of rubber rollers and consequently maintenance and spare parts costs.
• The J 10 machine is fully automated with robots performing piecing at the start-up of the machine, piecing after a break or a quality cut and doffing of full packages.

New ComforJet® yarn

The unique features of the ComforJet® yarn make it different from the other spinning technologies. The ComforJet® yarn, formed by the flow of compressed air, shows very low hairiness with short fiber ends and small loops. This results in high wash and pilling resistance. The specific ComforJet® yarn structure creates a high ability to absorb liquids.

The yarn softness and voluminosity lead to visibly higher fabric density and fabric evenness. Thanks to ComforJet® piecing technology the piecing is unrecognizable in the fabric, which adds to the fabric’s value. The consumer benefits from ComforJet® fabrics. The yarn and fabric structure has an extremely soft touch. ComforJet® fabrics have a long lifetime due to high wash and pilling resistance.

G 35 ring spinning machine

Rieter creates new momentum for ring spinning technology on the world market through continuous innovation. Very long machines up to 1632 spindles combined with efficient 4-spindle drive ensure very low energy consumption. Rieter’s patented SERVOgrip device is the convincing, mill-proven solution for smooth doffing with minimal fiber fly.

G35 ring spinning machines produce high quality ring yarns. With the optional device VARIOspin II, one can produce fancy yarn on G 35. Either elastic or rigid core ring yarn can be spun with the optional core yarn device.

K 45 compact spinning machine

The K 45 ComforSpin machine is modular in design and is available with up to 1632 spindles. Longer machines enable the fixed proportion of production costs per kilogram of yarn to be reduced and thus economic efficiency to be improved substantially.

Individual Spindle Monitoring (ISM) leads to higher output and quality. ISM is available in a basic version or with expanded analysis options on the SPIDERweb mill monitoring system. Easy, rapid replacement of the suction units ensures prompt adjustment of production to the yarn properties required by the market. The ComforSpin machine produces a wide variety of fashionable yarns, such as Com4®core, Com4®vario, Com4®twin and Com4®light.

R 40 or BT 923 rotor spinning machine

Rieter rotor spinning features high productivity combined with superior flexibility in terms of raw material and yarn structure. The fully automated rotor spinning machine with 500 spin boxes offers state-of-the-art technology for manufacturing ComfoRo® quality yarns with minimum energy consumption.

The R40 is available with 2, 3 or 4 robots. The new Rieter Yarn Clearer (RYC) - an optical yarn clearer - incorporates all important clearer channels.

A particularly strong point of the RYC is its rapid response to yarn defects caused by deviations in sliver count. The semi-automated machine BT 923 is specifically designed for economical production with manual assistance and combines high standards of yarn quality with very efficient machine operability.

The BT 923, now available with up to 400 rotors per machine, produces rotor yarns in the yarn count range from Ne 2 to Ne 40.

The semi-automatic piecing with AMIspin® leads to superb piecing quality. Supplementary equipment such as Qtop® for superior fiber preparation, AUTOvac for vacuum monitoring and the Rieter IQplus® yarn clearer and the fancy yarn device complete this attractive product.

Other product highlights from Rieter

C 60 high-performance card

With its unique geometry in the carding zone, the C 60 high-performance card provides one of the main building blocks for achieving financial success. With a working width of 1500 mm, output by the C 60 card is up to 50% higher than on conventional models – and is combined with superior sliver quality. The ratio of output to energy and space requirements is revolutionized by the C 60. It is available with coiler (CBA), integrated drawframe without leveling (SB module) and in the autoleveling version (RSB module) for use in the OE direct process.

E 66 / E 76 Comber

74 kg/h on the new, fully automated E 76 comber or 72 kg/h on the E 66 comber – these are the effective production figures of the new combers. The increase in output has been achieved by means of C•A•P•D 500 (Computer Aided Process Development). With 500 nips/min., up to 80 g/m batt weight, superior fiber selection and very good machine running behavior, the combers produce top quality with maximum economy. The ROBOlap fully automated lap changing and piecing system on the E 76 comber remains a unique feature.

RSB-D 22 double-head autoleveler draw frame - Single-head
autoleveling quality on two heads

Rieter is complementing its draw frame portfolio with the RSB-D 22 double-head autoleveler draw frame featuring a maximum delivery speed of 2 x 1100 m/min. Its completely independent machine sides and autoleveling functions are a unique feature in a double-head autoleveler draw frame. Each head therefore produces exactly the same quality and output that have become the benchmark from the RSB-D 40 single-head draw frame. Further advantages include reduced space requirements, low energy consumption and lower capital cost.

Energy saving – more important than ever before

Specific energy consumption (kW/kg of yarn) has continued to gain in importance in recent years in relation to manufacturing costs in textile production processes. Rieter Spun Yarn Systems has always given special attention to this sensitive aspect and takes it into account both in new developments and in retrofit kits for older generations of machines.

Contamination removal

The detection principle of THE VISION SHIELD and MAGICEYE M1 complement one another in an ideal manner. This fact guarantees, that any type of contamination in the blow room is detected and eliminated. The MAGICEYE M1 principle was also exhibited at ITM 2009. This principle of detecting synthetics is a breakthrough technology in the textile market. The most undesired contamination in spinning is white polypropylene. MAGICEYE M1 detects all sorts of plastics, including transparent, and white polypropylene. It also eliminates colored, white or transparent foil or fabric of natural or synthetic origin.

Original spare parts from Rieter Parts

It is important that the range of machines installed produce at the highest technical level. Regular maintenance and the systematic replacement of worn parts keep your production efficiency high. Rieter offers numerous upgrades for older generations of machines. Original Rieter technology components, retrofits and conversions were also displayed and latest parts’ innovations and how to implement the latest features in the spinning mill were also explained by the experts at the booth.
