From the Sector

Under the motto “People Matter” A+A 2023, a Trade Fair for Safety, Security and Health at Work, will revolve around the most important trends of our time: sustainability and digitalisation. Here, exoskeletons also play a prominent role as tomorrow’s ergonomic tools. An important conference in this field is WearRAcon Europe which will be held at A+A from 25 – 26 October 2023 for the first time.

The Conference will be organised by the Fraunhofer Institute IPA in cooperation with the Stuttgart University and the Wearable Robotics Association (WearRA). The 38th A+A Congress, which is held by Bundesarbeitsgemeinschaft für Sicherheit und Gesundheit bei der Arbeit (German Federal Association for Occupational Safety and Health - Basi) will be closely dovetailed thematically and in terms of content with it.

Being able to walk again despite a serious injury, handle heavy parts without outside help or simply do overhead work comfortably and for extended periods of time - the advantages of exoskeletons have already convinced numerous industries. Exoskeletons and wearables are now already being used successfully in industry and commerce, and major machine builders and automakers as well as the medical sector are continuing to experiment with man-machine connections. Currently, the global market volume for exoskeletons is valued by leading analysts at over US$20 billion by 2030.¹

The WearRAcon Europe Conference 2023 will provide new insights into the promising world of exoskeleton systems from different perspectives and, in conjunction with the A+A Congress, set future-oriented impulses. Lectures by renowned exoskeleton pioneers combined with testimonials presented by users from a variety of industries and keynotes by experts will round off the programme. And, like at the previous A+A, a Self-Experience Space will again be set up so that the exoskeleton systems of various manufacturers can be tested in realistic work scenarios.

In parallel with the Self-Experience Space, the large live study Exoworkathlon will also take place again. Trainees from various mechatronic training courses have to complete a concourse and perform holding, lifting and assembling tasks, which have been specially developed with the industry. Data is prospectively collected with different measuring sensors to measure the effects of exoskeletons. In the Exoworkathlon, the IPA focuses especially on prevention for young employees in order to raise awareness of the issue and counteract ailments at an early stage.

At the forthcoming Texprocess, Techtextil and Heimtextil shows taking place in Frankfurt from June 21-24 – members of the Swedish Textile Machinery Association TMAS will be showcasing a range of solutions aligning with the growing trend for more localised and automated textile manufacturing.

Digitalisation and the push for more sustainable, shorter and less expensive supply chains are currently making manufacturing in high-cost countries within Europe more attractive and there have been many other contributing factors to this over the past two years.

The Covid-19 pandemic exposed the vulnerability of many countries to shortages of essential items like PPE while at the same time making the full exploitation of new digital options essential during national lock-downs and long periods of restricted travel. The escalating cost of global transportation, as well as the growth of online retailing and the associated benefits of on-demand digital manufacturing, are further reinforcing the many benefits of short-run and near-shore new operations.

Secure supply
At Texprocess, for example, Eton Systems will be unveiling its latest Ingenious software solution which further enhances the company’s Opta Unit Production System (UPS) introduced in 2021.

“Our automated technology has already had a great impact on the productivity of thousands of garment production lines,” says Eton’s Managing Director Jerker Krabbe. “Our systems help producers across the world to reduce repetitive manual tasks and increase efficiency, which evens out some of the differences between production in high and low-cost countries, making reshoring a feasible option. Creating a diversified production portfolio with a mix of production facilities, some closer to home, makes for a more secure product supply.”

Flexibility
Imogo meanwhile recently installed the first industrial scale dyeing system in Sweden for many years. The Dye-Max spray dyeing line has the potential to slash the use of fresh water, wastewater, energy and chemicals by as much as 90% compared to conventional jet dyeing systems. It is capable of carrying out the application of a wide range of fabric pre-treatments and finishing processes, providing users with unbeatable flexibility in production.

“Here in Scandinavia, we are currently seeing an explosion of companies developing sustainable new cellulosic fibres – many from waste clothing – but a problem is that all of the environmental benefits they deliver can potentially be lost in the further processing, and especially in conventional dyeing,” observes the company’s Founding Partner Per Stenflo. “The Dye-Max system positively addresses this, but interest in it has not just been confined to Europe. We are currently seeing a lot of activity in Turkey – largely as a near-shore partner to European brands – but also in Bangladesh.”

Robotics at Heimtextil
ACG Kinna Automatic specialises in automation solutions for filled products such as quilts, pillows and mattresses and its live demonstrations of robotics in action have proved a magnet for visitors to Heimtextil. This year’s show will be no exception.

“The use of robotics is now standard across many industries dealing in solid goods, but the handling of soft materials such as textiles is a little more complex,” says Managing Director Christian Moore. “Nevertheless, it’s something we have successfully mastered, and our robotic systems are proving highly beneficial to their users. There is no ‘one-size-fits-all’ solution when it comes to automation and our approach is always to carefully examine where it will make the difference in each bespoke system. A focus is on identifying and eliminating bottlenecks which will increase product flows.”

During the Covid-19 pandemic, ACG Kinna drew on all of its automation know-how and extensive network of contacts to build a new nonwovens fabric converting and single-use garment making-up plant in a matter of weeks, in order to supply the Swedish authorities with urgently-needed medical gowns.

Instant colour
Localised textile production is also booming in the USA, where Coloreel has recently secured multiple orders for its instant thread colouration technology via its US partner Hirsch.

“Coloreel technology enables the high-quality and instant colouring of a textile thread while it is actually being used in production and can be paired with any existing embroidery machine without modification, while also making it possible to produce gradients in an embroidery for the first time,” explains VP of Sales Sven Öquist.

“Advanced rapid colour formulation software and high-speed drive technology allow a single needle to carry out what it previously required many multiples of them to do – and with much more consistent stitch quality. By instantly colouring a recycled white base thread during production, our system enables complete freedom to create unique embroideries without any limitations. Colour changes along the thread can either be made rapidly from one solid colour to another, or gradually, to make smooth transitions or any colouring effect desired. This provides big benefits when it comes to sustainability and design creativity.”

Milestone
Svegea will be promoting its latest EC 300 collarette cutting machine at Texprocess 2022. This machine is used by garment manufacturers around the world for the production of tubular apparel components such as waistbands, cuff and neck tapes and other seam reinforcements. With its E-Drive 2 system and fully automatic FA500 roll slitter, the EC 300 has an output of around 20,000 metres per hour.

“Advances in automation are only making the specialised, bespoke machines we engineer even more efficient and we are expecting a very busy year,” says Managing Director Håkan Steene. “The garment components our collarette cutters produce make it logical for them to be integrated into the operations of making-up operations, wherever they are.”

Sensors
The advanced yarn tension monitoring technologies of Eltex of Sweden meanwhile play an essential role in rectifying defects in  weaving, tufting and composite reinforcement operations.

“A correct tension of the warp and weft threads ensures proper machine operation,” explains Eltex Global Marketing and Sales Manager Anoop K. Sharma “The constant tension monitoring and automatic control of the tension of the thread help to overcome unnecessary problems.

“We continue to make advances in both the hardware and software of our tension monitoring systems, such as the EyE™ for the warping process. With the EyE™, the yarn tension values from all yarns are continuously updated and displayed on screen. In addition, tension values outside the warning level are indicated both on the sensor’s LEDs and on the screen for complete quality control. No fabric can be woven without the appropriate and correct tension.”

• Members of TMAS – the Swedish textile machinery association – have adopted a range of new strategies in response to the Covid-19 pandemic, aimed at assisting manufacturers of textiles and apparel to adjust to a new normal, as Europe and other regions emerge cautiously from lockdown.

“Many European companies have been forced into testing new working methods and looking at what it’s possible to do remotely, and how to exploit automation to the full, in order to become more flexible,” says TMAS Secretary General Therese Premler-Andersson. “Others have been taking risks where they see opportunies and there’s a new sense of solidarity among companies.

“It’s extremely encouraging, for example, that over five hundred European companies from across our supply chain are reported to have responded to the shortages of facemasks and PPE – protective personal equipment – by converting parts of their sites or investing in new equipment.”

New supply chains

Amongst them are TMAS members of the ACG Group, who quickly established a dedicated new nonwovens fabric converting and single-use garment making-up plant to supply to the Swedish health authorities. From a standing start in March, this is now producing 1.8 million square metres of converted fabric and turning it into 692,000 finished medical garments each month.

“In 2020 so far, we have seen new value chains being created and a certain amount of permanent reshoring is now inevitable,” says Premler-Andersson. “This is being backed by the new funding announced in the European Union’s Next Generation EU plan, with €750 billion marked for helping industry recover. As the European Commission President Ursula von der Leyen has stressed, “green and digital” transitions hold the key to Europe’s future prosperity and resilience, and TMAS members have new solutions to assist in both areas.”

Remote working

Automated solutions have opened up many possibilities for remote working during the pandemic. Texo AB, for example, the specialist in wide-width weaving looms for the paper industry, was able to successfully complete the build and delivery of a major multi-container order between April and May.

“Our new Remote Guidance software now makes it possible for us to carry out some of the commissioning and troubleshooting of such new lines remotely, which has been helpful” says Texo AB President Anders Svensson.

Svegea of Sweden, which has spent the past few months developing its new CR-210 fabric relaxation machine for knitted fabrics, has also successfully set up and installed a number of machines remotely, which the company has never attempted before.

“The pandemic has definitely led to some inventive solutions for us and with international travel currently not possible, we are finding better methods of digital communication and collaboration all the time,” says Svegea managing director Hakan Steene.

Eric Norling, Vice President of the Precision Application business of Baldwin Technology, believes the pandemic may have a more permanent impact on global travel.

“We have now proven that e-meetings and virtual collaboration tools are effective,” he says. “Baldwin implemented a home office work regime from April with only production personnel and R&D researchers at the workplace. These past few months have shown that we can be just as effective and do not need to travel for physical meetings to the same extent that was previously thought to be necessary.”

Pär Hedman, Sales and Marketing Manager for IRO AB, however, believes such advances can only go so far at the moment.

“Video conferences have taken a big leap forward, especially in development projects, and this method of communication is here to stay, but it will never completely replace personal meetings,” he says. “And textile fabrics need to be touched, examined and accepted by the senses, which is impossible to do via digital media today. The coming haptic internet, however, may well even change that too.”

Social distancing

The many garment factories now equipped with Eton Systems UPS work stations – designed to save considerable costs through automation – have meanwhile benefited from the unintentional social distancing they automatically provide compared to factories with conventional banks of sewing machines.

“These companies have been able to continue operating throughout the pandemic due to the spaced nature of our automated plant configurations,” says Eton Systems Business Development Manager Roger Ryrlén. “The UPS system has been established for some time, but planned spacing has proved an accidental plus for our customers – with improved productivity.”

“Innovations from TMAS member companies have been coming thick and fast recently due to their advanced know-how in automation concepts,” Premler-Andersson concludes.  “If anything, the restrictions imposed by the Covid-19 pandemic have only accelerated these initiatives by obliging our members to take new approaches.”
