high level of productivity.
Rieter’s Comber E 90 offers consistent quality thanks to reliable, real-time information with Rieter Quality Monitor.
TW特别报告
S总部位于Witzerland的Rieter报告说，其最新的Comber E 90实现了高水平的生产率。结合其高原材料的利用能力和经济的能源消耗，可以实现每公斤梳子的生产成本最低的成本。
In addition to these E 90 capabilities, Rieter’s customer Brazil-based Norfil S.A. Indústria Têxtil was particularly impressed by the continuous monitoring of the sliver quality. This makes unpleasant surprises in the yarn a thing of the past.
Comber E 90每小时可产生多达100公斤的梳子滑片。高梳子速度每分钟600 nips，以及机器的稳定且无故障的跑步行为，可以实现这种高标准的生产率。此外，据Rieter称，E 90提供了所有质量水平，从低NOIL提取的纱线呈高稠度。
高灵活性，
Consistent Quality
Flexibility was also an important factor for Norfil when it was considering the E 90 comber. Norfil is a family-owned business in the state of Paraiba founded in 1989. Thanks to continuous investments in technology and automation, the company now produces 2,400 tons of yarn per month. Using raw material from its own cotton plantation, Norfil manufactures high-quality yarn for the apparel industry, with combed cotton yarns as its main product. The company was looking for a comber that could not only deliver consistently high quality, but would also have the capability to produce different quality levels with high consistency. Norfil’s new Rieter E 90 comber meets these expectations. The operating unit is very easy to use, which enables Norfil to flexibly change the quality requirements. The new technology components developed for the E 90 significantly reduce the noil extraction and lead to improved raw-material utilization.
Real-Time Information On Sliver Quality
Production at Norfil takes place with total control over the sliver quality thanks to the Rieter Quality Monitor (RQM) technology. This proven Rieter draw frame technology is now also fully integrated in the E 90 comber. A sensor continuously monitors the sliver quality produced by the comber and constantly delivers exact and reliable information regarding the current quality level. This allows deviations in sliver weight and sliver evenness to be detected early. As a result, unpleasant surprises in the yarn due to changed settings in the comber are a thing of the past at Norfil.
诺菲尔老板法比奥·博格（Fabio Borger）说：“新的comber E 90夺走了许多事情，以便我们可以专注于我们的优先事项。”“这主要是由于Rieter质量监视器（RQM）。它很容易调节，我们可以信任设置。梳子以高生产率的速度非常始终如一地提供承诺的质量。”
Quick Change Of Noil Level
另一个请求uirement of Norfil for its new comber was the ability to quickly change the noil level. Using Rieter’s E 90, Norfil can quickly change from 14 percent to 24 percent, which extends the company’s working range and saves raw material. The company can now produce sliver with a low noil level of 14 percent with maximum consistency for Ne 30 at a rate of 550 nips per minute — with enough headroom to easily accelerate to 600 nips per minute if needed(see Figure 1).Thanks to the huge noil savings with the E 90, Norfil also managed to cut costs while maintaining quality.
Rieter has developed new technology components for the E 90 that significantly increase the range of applications of the top comb and circular comb. With this new development, it is possible to reduce the noil extraction amount by 3 percent without the need to change the settings of the top comb and circular comb. As a result, raw material utilization is improved significantly with low noil extraction. Maximum output remains consistent even when producing high-quality yarns.
Norfil is very satisfied with the ongoing support from Rieter technicians throughout the E 90 installation project. In cooperation with Rieter technologists, Norfil was able to implement new ideas, resulting in a new combing process designed for their specific needs. The comber E 90 is the best solution for Norfil and the company has already ordered the next batch of combers.
