Keeping on an even creel with the
Eltex of Sweden will introduce a yarn tension
monitoring system for woven fabrics at ITMA 2019 from June
20-26th in Barcelona, Spain.
Unlike yarn tension monitors that are fitted solely on the
weft insertion systems of the weaving machines in a modern mill,
Eltex is introducing the EyETM system for the warping process
prior to weaving – and instead of monitoring only the tension of
the six-to-eight yarns fed by the weft insertion system they are
keeping a close eye on literally hundreds.
“Several hundred yarns can be fed from the creels during the
warping process compared to only a few weft insertion yarns
during weaving,” explains Brian Hicks, managing director of
Eltex. “In 2015 we decided to broaden our portfolio and move
into multiple end application in the warp preparation in
response to customer demand. It’s obviously a much different
process, but we completed development in Spring 2018 and in less
than a year have had better than expected demand from a diverse
sub-set of markets, with a first full installation already
operational at a premier UK fashion customer.”
With warping that can operate at speeds of 500 metres a
minute, the yarn tension values from all yarns are continuously
updated and displayed on a screen. Tension values outside the
warning level are indicated both on the sensor’s LEDs and on the
screen. It is possible to expand a sector of the display to have
a detailed view including the position ID and the cN value for
the yarns in this sector.

“Tension monitoring for multiple ends has been a great
challenge to achieve but we’re confident the system will
generate a lot of interest at ITMA 2019,” Mr Hicks says.
“Perhaps the biggest challenge of all has been getting such a
comprehensive system – with a sensor for each individual yarn –
down to an acceptable price for the industry, but I’m happy to
say, we’re there now. The EyETM will allow mills to greatly
reduce problems, not only when warping, but also in the
subsequent weaving or tufting processes.
With its research and development work primarily carried out
at its headquarters in Osby, Sweden, and North American sales
and service operated from its subsidiary in South Carolina, the
manufacturing plant of Eltex has been located at Templemore in
Ireland since 1976, providing significant advantages in terms of
high flexibility and logistical services to customers on both
sides of the Atlantic.
Eltex is a member of TMAS – the textile machinery association
of Sweden which will have a significant presence at ITMA 2019 in
“The latest technologies being developed by Eltex perfectly
illustrate how Sweden’s long tradition and history of textile
production are being combined with a good climate for
innovation,” says TMAS Secretary General Therese
Premler-Andersson. “There will be many more innovations on show
from our members at ITMA 2019.”
Eltex will be at stand B102, in
Hall 4 at the Barcelona exhibition.
