Compact Spinning Compact-Spinning Machine K 48 Fully compacted yarns produced with high flexibility and speed

K 48 Highest Spindle Speed and Full Flexibility 2

With spindle speeds of up to 28 000 rpm, production is increased by 12%. With the High-Speed Package (34 mm spinning ring, 16 mm DUI tube/spindle dimension, LENA 28 spindle) the production limits have been considerably extended. The fully electronic drafting system FLEXIdraft maximizes the production time and allows extraordinary flexibility. Systems for slub, core and twin yarns are available on full machine length.

The integrated individual spindle monitoring system ISM premium checks the running behavior of each spinning position. Combined with the fully automated piecing robot ROBOspin, the K 48 constantly produces high quality compacted yarn with less dependency on work force. 4

Rieter . Compact-Spinning Machine K 48 Highest Spinning Speeds The further development of the proven compact-spinning machine K 48 with the High-Speed Package brings enormous customer benefits in terms of productivity and energy savings. 12% higher production The production output of a ring spinning machine is directly related to the level of the spindle speed. With a spindle speed increase from 25 000 rpm to 28 000 rpm and delivery speeds up to 40 m/min, the new K 48 model allows to produce 12% more yarn at the same time. Developments in the spindle design of Rieter spindles coupled with optimization...

Rieter . Compact-Spinning Machine K 48 Spindle LENA 28 for high speed and low energy consumption The selection of the optimum spindle is a key factor for high productivity with consistently uniform yarn quality. With the latest development in spindle construction, the production limits have been considerably extended. With the new HPS 28 and LENA 28 spindles, revolutions of up to 28 000 rpm can be run. Both spindles have a second damping system to remarkably reduce the bearing load and the noise level. Low vibration, low maintenance and a long service life are the distinguishing features of these...

Rieter . Compact-Spinning Machine K 48 Proven Concept for Low Energy Spinning Energy-saving 4-spindle tape drive The Rieter 4-spindle tape drive is energy-efficient and easy to handle. The large enlacement of 90 degrees ensures that every spindle operates without failure, even with minimal contact pressure. The low contact pressure guarantees low energy consumption. Save up to 6% energy with the LENA spindle The LENA spindle has been specially developed for high spindle speeds and low energy consumption. A whorl diameter of 17.5 mm and other optimizations make a significant impact on energy efficiency....

Rieter . Compact-Spinning Machine K 48 Low energy consumption due to one-duct system Lower air flow rate thanks to air guide element The K 48 requires significantly less energy for compacting in comparison to other solutions. This is thanks to a unique compacting system and energy-efficient technology components. The one-duct system for suction reduces the energy consumption needed to generate the necessary underpressure. The large cross-section of the suction duct lowers the air speed and reduces the air resistance. Rieter one-duct system for ring and compact spinning lowers air speed and energy...

Rieter . Compact-Spinning Machine K 48 Break down of total energy consumption The end spinning machine accounts for a large part of the energy consumption in ring and compact yarn production. For this reason, Rieter is particularly investing in energy-efficient technologies and developments. More than 80% of the energy is consumed for the spindle drive and here the proven 4-spindle tape drive with only one large drive motor shows advantages. Lower torque requirements in the drafting system with the sieve drum result in significantly lower energy consumption. Field tests have shown a saving of...

Rieter . Compact-Spinning Machine K 48 Fast and Easy Parameter Change Set yarn parameters electronically The electronic drafting system drive FLEXIdraft for the compact-spinning machine K 48 uses frequency-controlled motors. This electronic drafting system drive means less work for operating personnel. Parameters such as yarn count and twist can easily be adjusted on the machine display. There is no need to change gear wheels or make any other mechanical adjustments. The operator can also change the Z yarn twist direction or the S yarn twist direction on the operating unit. Mechanical adjustments...

Rieter . Compact-Spinning Machine K 48 Fully Automated Piecing Robot ROBOspin ROBOspin is the first fully automated piecing robot for ring spinning and compact-spinning machines. One robot per machine side repairs ends down that occur during startup or while the machine is running. The industry’s first fully automated piecing robot in ring spinning Consistent high performance proven in spinning mills The robot travels directly to the affected spinning position and repairs the ends down in the shortest time possible. As a result, the complete piecing cycle runs fully automatically – from finding...
