Uster® Sentinel is The Key to Optimized Yarn Production
Ring spinning machines are getting longer. And that’s a trend that is noticeable in some markets, where ringframes run to as many as 2,000 spindles – or about 70 meters in length. Even with good human eyesight capable of reaching 5,000 meters, it’s still not possible to have a total overview of end-breaks along the full extent of the frame. Only an automated system can monitor if the spindles are all operating correctly.
RING SPINNING OPTIMIZATION
It’s a fact that high-performance potential and enormous ring-spinning machine capacity are worthless if spindles are at a standstill because of end-breaks. Uster® Sentinel is the answer: its bobbin build-up report is the key to optimized yarn production.
The system’s unmatched detection of end-breaks provides the basic platform. Uster® Sentinel guides machine operators straight to spindle breaks, through clear and simple indications by red light dots.
End-break levels are a key indicator of ring spinning performance, so Uster® Sentinel’s intuitive bobbin build-up report includes every parameter influencing end-breaks. Clear visuals point to exact reasons for breaks, making optimization easy. Spinners can then make the required improvements, focused on ambient conditions, wear of mechanical parts and machine speed. Its easy-to-use software gives a rapid, tailor-made overview of machine performance, highlighting exactly the most relevant production and laboratory data. An attractive feature is the real-time information on energy consumption. Only with real-time data can mills take the opportunity of immediate optimization.
THE REAL DIFFERENCE
Combining this total control of end-breaks with Uster® Roving Stop leverages the efficiency of yarn production. The instant stop of roving feed at an end-break reduces waste significantly and makes raw material usage more costffective.
Calculations show that 70% less pneumafil waste equates to a saving of nearly 1% in raw material, based on current spinning conditions. Obviously, this makes for a shorter investment payback too.
Reduced levels of waste and uncontrolled fiber fluff prevent quality issues around neighboring spindles and along the entire machine. Better operating conditions and reduced repair times result in higher yield and fewer quality issues.
THE SUMMIT OF PRODUCTION EFFICIENCY
Human limitations on eyesight and speed are irrelevant with Uster® Sentinel in place – and even the multiple number of spindles in a ringframe makes no difference. Downtime is kept at the lowest possible level – an unbeatable achievement also thanks to the unique design of Uster’s ring spinning optimization system. The streamlined and uncluttered profile of the Uster® Roving Stop is geared to optimum machine performance. The distinct compact shape ensures easy and effortless piecing access, since its sensors don’t need to be positioned too close to the ring, which also saves time and speeds up responses.
For the ultimate in quality optimization, Uster® Sentinel is ready for connection to the Total Testing Center of Uster® Tester 6.Here, data from all spinning processes is integrated and inter- preted, providing comprehensive guidance for users to maximize both efficiency and quality.
