USTER® ring spinning optimization system now offers much more
than the end-break detection
USTER® SENTINEL is much more than
an end-break detection system. It is a comprehensive solution
for ring spinning optimization, with benefits in quality,
productivity and efficiency. Data can now be integrated with the
Total Testing Center through USTER® TESTER 6, giving spinners an
overview of quality through all process steps in the mill, for
focused control of production management. Adding USTER® ROVING
STOP enhances the economic advantages still further, reducing
waste by stopping the roving feed immediately an end-break is
USTER® SENTINEL’s bobbin build-up report is the key to
optimized yarn production. The system’s unmatched detection of
end-breaks provides the basic platform, which is extended to
total control of end-breaks when combined with USTER® ROVING
STOP. The instant stop of roving feed at an end-break will
reduce waste significantly and make raw material usage more
cost-effective. Calculations show that 70% less pneumafil waste
equates to a saving of nearly 1% in raw material, based on
current spinning conditions. This obviously makes for a shorter
USTER® SENTINEL – the ring spinning optimization
system with USTER® ROVING STOP.
Designed for top productivity
Using USTER® SENTINEL with USTER® ROVING STOP improves
productivity and cuts down the risk of quality problems in ring
spinning. Potential quality claims are avoided, since waste
material and uncontrolled fiber – which could affect neighboring
spindles and the entire machine – are greatly reduced by the
USTER® ROVING STOP.
Overload on rollers is also prevented, ensuring higher
productivity through reduced lapping. These benefits together
can be expected to extend the service life of spinning
components such as aprons, cots and cylinders by around 20%.
The design of USTER® ROVING STOP is striking. Its streamlined
and uncluttered profile is geared to optimize machine
performance. The unique compact shape leaves operators clear
access, saving time and speeding up responses. And its smart
design enables the USTER® ROVING STOP to implement a rapid and
complete separation of the process, to avoid raw material waste.
Higher yield and fewer quality
The USTER® SENTINEL brings a new approach to quality,
productivity and efficiency in ring spinning. Bobbin build-up
information and end-break detection are the basic functions, but
total optimization is the result. The intuitive reports on
bobbin build-up include every parameter influencing end-breaks.
Clear visuals point to exact reasons for breaks, making
optimization easy. The mills benefit from improvements in
ambient conditions, service life of mechanical components – and
The machine performance is displayed in real-time, giving a
fast overview of the most relevant production and laboratory
data – as well as the machine’s energy consumption. The
well-established expert system supports mills with clear
guidance to profitable optimization.
Higher yield and fewer quality issues also result from
reduced repair times. Badly-performing spindles are reliably
identified and the USTER® SENTINEL guides machine operators
quickly to spindle breaks, through clear and simple indications.
Other issues which often impair the spinning process – such as
idle, rogue and off-quality spindles, as well as spindle slip –
are all monitored for fast response.
Profitability: The ultimate goal
USTER’s ring spinning optimization system maximizes
profitability where it matters most. USTER® SENTINEL measures
and controls the most expensive process in yarn manufacturing.
It monitors the productivity of all spindles, as well as
providing the required links and information to help the
spinning mill optimize both machine performance and the entire
Connecting USTER® SENTINEL to the Total Testing Center of the
USTER® TESTER 6 opens the way to extended analysis, based on
centralized quality data from all spinning processes. This is
the route to management of a spinning mill with quality in mind.
Adding USTER® SENTINEL data to this creates the ultimate quality
optimization package. This is a significant further development
milestone, supporting spinners to achieve the ultimate goal of
excellence in quality and profitability.
