Rieter’s latest combing set (E 36 and E 86) has achieved the greatest productivity worldwide since its technology advantage is based on optimal interaction between machine and technology.
Thanks to continuous advancements, the E 36 OMEGAlap concept has been improved to achieve an increase in production of 20% to over 600 kg/h at a constant speed of up to 230 m/min is the result.
With this production rate, the OMEGAlap is far superior to conventional machines. The influence of the OMEGAlap on the economic performance of a combing section is enormous. The high production allows a reduction in the number of preparatory machines. This noticeably reduces the number of can changes and sliver piecings. Fewer personnel are needed.
As an example, the personnel requirement of a combing set in a compact spinning facility with 76,000 spindles was calculated. Compared to other machine manufacturers, the personnel requirement can be reduced by 3 persons. This is realised by the efficient combing preparation, the SERVOlap fully automated lap transport system and the comber including the ROBOlap automated lap changing and piecing system. The labour saved by the combing preparation machine can be up to 20% and that reduces manufacturing costs.
Similarly, the new E 86 comber features a speed increase of 10% compared to the previous model. In the short and medium staple ranges, combing can be made with 550 nips per minute, and that without compromises in the combing quality. In practice, Rieter combing sets supplies plants with approximately 25,000 compact spindles.
The strength of the E 86 comber lies in a high level of cleaning as well as excellent running performance with high nip rates.
The E 86 achieves fewer imperfections in the yarn (thin places, thick places, neps) at the same noil removal level compared to combers from other manufacturers. The high degree of cleaning has no effects on the fibre quality, which means that fibre length remains unchanged and thus the yarn tenacity at a high level.
Furthermore, the E 86 attains an improved dust and trash elimination of up to 20%. The short fibre content, the hairiness as well as the evenness in the yarn remain unchanged.
It means that in both examples, a higher cleaning effect is achieved by means of stronger combing intensity without compromises in the combing quality.
Better yarn quality has been achieved with the E 86 compared to another manufacturer. At the same, production performance and the same noil removal, the imperfections are lower by 40%.
The raw material is a considerable cost factor in any spinning mill. With the E 86 noil removal mechanism, raw material can be reduced by up to 1% at equally good yarn quality, which generates cost savings of up to USD 55,000 annually.
The production performance also positively affects the costs of the spinning mill. The E 86 has the potential to achieve a 10% higher production in comparison to the previous model, at the same noil removal and yarn quality which corresponds to a saving in manufacturing costs of about USD 20,000 per year.
The E 86 comber with its high production at simultaneously high quality leads the way in combing. Individual quality demands can be realised thanks to high-value technology components. The established, fully-automated ROBOlap lap changing and piecing system is the standard for a modern combing facility. Together with the unique OMEGAlap preparation, the highest production per set on the market has been achieved, according to a release.
