Rieter Short-Balloon Setting Upgrade Increased Productivity By 2.5%

Masood Fabrics Ltd in Pakistan enhanced the performance of eight compact-spinning machines K 46 with the support of Rieter. The short-balloon setting upgrade enabled the spinning mill to increase the spindle speed by 500 rpm while reducing yarn breaks from 60 to 50 per 1000 spindle hours. This boosted productivity by 2.5%.

Lowering yarn tension with reduced balloon height and diameter supports higher spindle speed.

Malik Asad Ullah, Technical Director of Masood Fabrics Ltd (Spinning Unit), Pakistan, says “The implementation of short-balloon setting in the existing compact-spinning machine K 46 has resulted in a 2.5% production increase. Moreover, the reduction in yarn breaks ensures reduced operators’ workload and smoother machine performance.”

Masood Fabrics Ltd operates eight Rieter compact-spinning machines K 46, installed in 2017, dedicated to produce high-quality compact yarn at peak productivity. The company sought a solution to further enhance machine productivity. The primary goals were to increase spindle speed while maintaining existing yarn break levels and ensuring consistent yarn quality. Although the machines were operating smoothly, the customer aimed to push production limits to achieve greater operational and cost efficiency.

Increased spindle speed and reduced yarn breaks leading to higher productivity after short-balloon setting upgrade.

Expanding technological limits
Rieter proposed the short-balloon setting upgrade, a solution designed to shorten the balloon height during cop build-up. This innovative upgrade balances various balloon forces throughout the cop build-up process. By reducing the yarn balloon’s diameter and circumferential speed, the short-balloon setting upgrade lowers yarn tension. This enables an increase in spindle speed and offers the possibility of reduced yarn breaks.

Higher performance achieved with the compact-spinning machine 
With the implementation of the short-balloon setting upgrade, Masood Fabrics Ltd achieved a 2.5% increase in productivity. The spindle speed rose from 21 800 rpm to 22 300 rpm for a yarn count Ne 40, cotton combed compact yarn production. Additionally, the reduction in yarn breaks from 60 to 50 per 1000 spindle hours contributed to increased machine efficiency. This successful implementation highlights Rieter’s commitment to enhancing machine performance and delivering value to customers.
