Rieter’s Performance Kit Boosts Productivity And Yarn Quality

Sreedhara Textiles upgraded its ring spinning machines G 32 and G 36 with Rieter’s ring spinning performance kit. The company achieved 3% increase in production, coupled with reductions of 3% in power consumption, 18% in yarn imperfections and 9% in winder cuts.

Some ring and compact-spinning machine components may look small and simple, but the impact they have on the machine’s performance is huge. Maintenance of these key components plays a vital role in achieving a desired and consistent performance output throughout the machine lifecycle. Anantha Kumar, Factory Manager, Sreedhara Textiles Pvt. Ltd., said, “After the installation of the performance kit on the ring spinning machine, we got a substantial improvement in terms of productivity and yarn quality. The variation between cops was drastically reduced, which helped improve the performance of the winding machine.”

Performance kit: A powerful maintenance solutions package
Sreedhara Textiles, one of the many prestigious Rieter customers based in southern India, faced yarn quality deterioration and performance issues while attempting to elevate spindle speed for enhanced productivity. Rieter’s After Sales team conducted a thorough analysis, revealing that certain key components required replacement as they had exceeded their recommended lifetime of more than seven years. This included, for instance, the uneven movement of the ring rail due to bearing failure in the tape tension roller which resulted in poor cop buildup, leading to an increase in winder cuts. Additionally, the variable tension of the torsion spring guiding the bottom apron contributed to a deterioration in yarn quality.

Based on these findings, Rieter recommended the customer to invest in the performance kit: a maintenance solution package designed for ring and compact spinning machines. The performance kit (Fig.2) consists of key components and parts in the drafting and spinning zones. The drafting zone components ensure proper stretching and drawing of the roving for the highest quality, while the spinning zone components enable an even cop buildup. The components are strategically grouped, considering their criticality and impact on the machine’s performance. Replacement of these parts will help increase the spindle speed for high productivity, achieve better yarn quality, lower power consumption and maintain the smooth performance of the machine for several years.

The performance kit delivers key improvements 
Sreedhara installed the performance kit on its six ring spinning machines G 32 and G 36. The improvements (Fig.3) are seen immediately after the installation of the performance kit in terms of productivity, yarn quality and power savings. Sreedhara achieved the following benefits:  3% increase in production, 3% reduction in power consumption, 18% reduction in yarn imperfections, 18% reduction in hairiness CV% and 9% reduction in winder cuts.

The between-cops variations are reduced due to the installation of new parts, resulting in uniform package quality and better performance of the winding machine. In addition, replacing the old parts with Rieter’s original parts extends the lifetime of the ring spinning machine.
