Improving efficiency is one of the primary goals for
textile mills in order to stay competitive. With continuous technological
advancement, there are many efficiency opportunities that exist in the weaving
process, such as greater flexibility, higher speed and better connectivity. At
ITMA 2019 in Barcelona, some exhibitors demonstrated their latest innovations
to the visitors.
Flexibility: Stäubli boosts the overall
efficiency for future-oriented mills
At ITMA 2019, Stäubli
provided a complete overview of its range of solutions for future-oriented
weaving mills and sock knitters – fully in line with the company’s commitment
to remain in close contact with its customers and meet the market’s needs as a
key partner.
Fritz Legler, Head of Marketing,
Sales & Service, Stäubli, took a group of textile journalists on a tour
around the booth to view a wide range of machinery and explained how the
company’s solutions can boost the overall mill efficiency.
As introduced, the SAFIR
series of drawing-in systems offers unique advantages thanks to AWC (Active
Warp Control), Stäubli’s exclusive yarn-repeat management system.
“AWC is based on optical,
non-contact recognition and measurement of yarn characteristics using two cameras.
High-performance processors analyse the images and deliver precise data at
millisecond intervals on the condition of the warp yarns being processed,” he described.
At the fairground, the
SAFIR S60 automatic drawing-in system was in operation with one drawing-in
truck and featuring the standard AWC feature ‘double-end detection’ as well as other
AWC functions.
Another highlight at the
booth was the new S1792 cam motion which expands the broad range of
frame-weaving solutions.

The new cam motion with 10
levers provides greater flexibility in air-jet applications. This cam motion is
used in conjunction with the high-performance e32/e33 transmission, which
features maintenance-free bearings and low maintenance requirements, resulting
in reduced downtime and lower maintenance costs.
The LXXL Jacquard machine
equipped with revolutionary NOEMI electronic system which ensures large-format
weaves for luxury and technical fabrics, was also introduced.
He illuminated, when
high-speed weaving of complex applications such as airbags or African damask is
required, the LX series assures reliable operation and correct hook selection
thanks to an additional recognition technology: the new NOEMI electronic
system, which features fewer connectors and ensures extremely stable data
transmission. NOEMI minimises electrical consumption and supports the Stäubli
hallmark characteristics of the LX/LXL/LXXL machines such as reliability,
productivity, and longevity.
In addition, visitor saw
the new-generation machine for name selvedging: the N4L Jacquard machine. The
N4L is Stäubli’s latest answer to the challenges of selvedge weaving, allowing
the weaving of complicated patterns at high speed using delicate and precious
yarns for high-fashion fabrics.
The machine is available in
two formats: 80 or 128 hooks. It features robust construction and dust-proof
design. The Jacquard heads are protected by aluminium beams in a perfect
ergonomic design, allowing easy installation and sliding over the beam for easy
changes and adaptation.
According to him, for
carpet-weaving mill, the ALPHA 500 carpet weaving system which adds immense
flexibility, is an ideal choice. It weaves high quality applications and allows
responding swiftly to rapidly changing market demands. Visitors had the opportunity
to observe the high-performance operation up close, including the latest
servo-controlled dobby of the UNIVAL 500 series and the unique servo cutting
device that produces carpet surfaces of unequalled evenness.
Besides weaving solutions, Stäubli
offered D4S toe closing device to shorten sock knitting production. Stäubli’s
D4S automatic toe closing device rapidly closes the sock on the knitting
machine with a smooth seam, significantly shortens sock production, ensures top
quality and uniformity of the product, and makes for very short idle times.
The automatic sock pick-up
and seaming operations are electronically controlled by the 2900SL controller,
and this setup will boost the performance of any mill producing socks, woollen
stockings, pantyhose, or medium-to-large diameter knitted goods used in various
sectors.
Speed: Itema

Connectivity:
Picanol’s
data-driven machines maximize productivity
At ITMA 2019, Erwin Devloo, Marketing Communication
Manager, Picanol, told CTA: “With our slogan ‘Let’s grow together’, we
demonstrate our goal to grow together with our customers. We not only sell
machines, but also provide services and supports to our customers. We have our
marketing and sales strategies in line with the market demands.”
He said the increasing
awareness regarding environmental topics, increasing costs and the availability
of resources and skills, as well as the digital revolution, has pushed the company in new
directions.
For this reason, Picanol’s products are designed with a focus on four principles: smart
performance, sustainability inside, driven by data and intuitive control.
Devloo described the current trend is about “evolution
rather than revolution”. Industry 4.0 is now a buzzword and the company has
been working on it for a long time, ever since the first introduction of
electronics on weaving machines in the 1970s.
“When we look at our machines, there are sensors
inside to capture data. That’s why we called our machines ‘data-driven’,” he explained.
The systematic use of electronic controls and
sensors has made it possible to generate data on a continuous basis. This in
turn serves as input for different software programs which automatically adjust
the running of the machine for maximum efficiency.

“We will continue to be a trendsetter in this
field, further deploying Industry 4.0 in the weaving industry,” he underscored.
“At the end, the textile industry will be completely changed and everything
will be integrated.”
As a proof of the company’s commitment to
these four principles, Picanol presented its latest
developments in rapier and air jet technology.
The world premiere of a
brand new airjet machine, the OmniPlus-i, which
represents a new benchmark in airjet weaving,
was held at the show.
“This further builds on the
solid base of nearly 40 years of experience in airjet weaving, during which
over 100,000 airjet machines have so far been shipped,” he said.
OmniPlus-i is featuring a redesigned reed
motion, optimized relay nozzle set up and can be combined with SmartShed, the
full electronic controlled shedding motion.
He pointed out that SmartShed is a logical next
step for digital transformation. This together with an abundant use of sensors generates
lots of data that fuel real-time optimization algorithms and promise further
gains in productivity when combined with other data, even from other, different
machines.
In total, Picanol had 12 machines on display. In addition to 5 new airjet weaving
machines, Picanol also showcased 5 rapier
weaving machines with many new developments. Furthermore, a rapier machine in
Jacquard execution was on display at the Bonas
booth and a terry airjet at the Stäubli booth.
Commenting on the market situation, he mentioned
that China, India, Pakistan, Bangladesh and Turkey are important markets for
the company and he expected these markets to continue to flourish in the
future.
“We have a dedicated product management team to
find out the market needs and then translated them into new improvements,” he
added.
