Increasing the Output of Rieter E 7/5 and E 7/5a Combers

November 21, 2011 - Switzerland

Production bottlenecks in combing operations can be avoided - by the systematic conversion of existing machines. Find out more about the advantages of the conversion kit for the E 7/5 and E 7/5A combers. These conversion kits are quickly delivered and have an immediate impact on output.

The E 7/5 and E 7/5A generations of combers have reliably done their job day after day for many years. The production potential of these combers can be exploited to the full by this conversion, which enables nip rates to be increased from 250 nips/min. to a maximum of 350 nips/min. Numerous customers have made this conversion in recent years. They report positive results - higher production volumes and improved quality values of the combed sliver.

Original technology components make it possible

The conversion kit consists of several modules. Rieter technology components interact ideally - only in this way can increased output and enhanced quality be achieved. The high-performance nipper, the circular comb and the top comb - these are the 3 essential technology elements in this conversion kit. A new main motor enables nip rates to be increased. (Fig. 1)

The Rieter high-performance nipper enables output to be increased by up to 15%. The higher clamping force of the nipper ensures that the lap is grasped more firmly and enables batt weights of up to 80g/m to be processed. This results in fewer imperfections and in raw material savings with the same noil extraction rates. (Fig. 2 / Fig. 3)

The PRIMACOMB® circular combs are very important for trouble-free running behaviour, the desired noil extraction rate and the required yarn quality. The circular combs are a core competence of Rieter. They can justifiably be described as the heart of every Rieter comber.

The distinguishing feature of Ri-Q-Top top combs compared to conventional top combs with needles is better self-cleaning and thus reduced soiling. Cleaning cycles are therefore up to 4 times longer. More effective top comb action is achieved due to optimum tooth shape and cross-section. More short fibres, dust, dirt, neps and seed trash are removed.

Rieter combers fulfill the highest standards from the first moment of commissioning and over many years. The special conversions kits developed by Rieter enable the growing demands in terms of productivity and quality in spinning mills to be met.
