From the Sector

Eltex of Sweden, a pioneer in the adoption of electronic sensors by the weaving machinery industry, is marking its 60th anniversary this month.

The electronic detection of broken or missing weft yarns during production was the problem Eltex founders Åke Rydborn and Ragnar Henriksson set out to solve with the development of the world’s first electronic weft-stop-motion. Its potential was recognised on its introduction at the 1963 ITMA exhibition in Hannover, Germany, leading to the foundation of the company in a modest 12-square-metre workshop in Älmhult, Sweden, in February 1964.

By 1968 the company was operating from a modern 3,000-square-metre plant and beginning to establish a global presence, introducing the first all-in-one printed circuit board (PCB) for its sensor systems in 1971. As exports increased, further Eltex operations were established in the USA and Ireland and the company expanded its product range including energy control devices, temperature and humidity loggers, food handling safety systems, and military grade battery chargers. Further textile milestones in parallel to advances in weaving technology included optical arrival detectors for air-jet weaving machines at the beginning of the 1980s, and the QTV system for warp preparation, which introduced digital stop-motion control to the industry at the start of the 1990s. In 2009, the company branched out into carpet tufting, first with the CoTS clamp-on tube sensor for tufting machines, followed by the Compact sensor for tufting machines in 2013. In 2019 the Compact II further cemented the company’s position in this sector.

Newly developed Eltex EyETM and ACT-R
Most recently, Eltex has launched the Eltex EyETM system for the monitoring of yarn tension on warp beams. Not only does it eliminate problems when warping, but also in the subsequent weaving or tufting processes. Eltex EyETM monitors the yarn tension on all positions in real-time and a minimum and maximum allowable tension value can be set. If any yarn’s tension falls outside these values the operator can be warned or the machine stopped.

The Eltex ACT and ACT-R units meanwhile go beyond yarn tension monitoring to actually control yarn tension. This extends the application range greatly. The plug and play system automatically compensates for any differences in yarn tension that arise, for example from irregularities in yarn packages.

Eltex has been owned by Brian Hicks, Seamus O’Dwyer and Jonathan Bell since 2007, following a management buy-out and the subsequent formation of Eltex Global Holdings in Ireland. Today, its head office, Eltex of Sweden AB, is in Osby, Sweden where it provides research and development, administration and global sales for the group. Eltex Manufacturing in Ireland is now the group’s primary production facility and Eltex US, Inc. provides sales and service for North America.

BTMA member Dent Instrumentation – a specialist in contactless yarn sensors – has become an employee-owned business following the formation of a new Employee Ownership Trust (EOT).

The company, based in Colne, Lancashire, has been family owned since its founder Geoffrey Dent secured a patent for the very first contactless yarn sensor in the 1960s. It has been successfully run by his son Andrew and the family for many years.
“This deal ensures a smooth succession as well as the preservation of the company’s core family values and the Dent Instrumentation name,” said Managing Director Colin Hull. “The EOT structure will maintain the integrity of the business for years to come.”

The liability of Dent sensors makes them integral to the yarn spinning and winding processes and they have become a standard throughout the textile industry, recognised for their quality, performance and value. They are used by major manufacturers of textiles and textile machinery under either Dent or OEM machine builder brands.

The recent Techtextil show in Frankfurt emphasised the diversity of applications for nonwovens and technical textiles, according to finishing technology specialist Monforts.

“We fielded enquiries at top management level from an extremely wide range of companies, all with very different ideas for new product applications during the show,” said Alexander Fitz, who joined the company a year ago as engineer for textile technologies and co-ordinator of the Monforts Advanced Technology Centre (ATC). Fitz brings a background in both technical textile technology and processes to the role, having previously worked for a nonwovens machinery builder and a roll-goods manufacturer.

Trials
“We are now looking forward to interesting new trials and pilot production runs, as well as the commissioning of new orders for machines resulting from the extremely busy exhibition,” he says. “Obviously, everyone at the moment is looking to make energy savings, and we have developed a range of options for helping companies increase their resource efficiency, both on new lines and as retrofitted systems, but this is not stifling innovation at the new material level.

“There was a lot of interest in what is possible with the Montex®Coat coating system and the range of different techniques it enables, and at our ATC in Mönchengladbach, a Montex®Coat unit is integrated into the full technical textiles pilot line, on which it is possible to run new fabrics in widths of up to 1.8 metres.”

Explosion proof
The technical textiles line at the ATC incorporates a Montex four-chamber stenter and is fitted with an explosion-proof coating application chamber in order to allow treatment to be carried out with organic solvents and other volatile materials.

Every single component within the chamber has to meet the standards of the European Union’s ATEX directives for working in a potentially explosive atmosphere. A range of sensors linked to alarms operate at various levels within the chamber to ensure the specified lower explosion limit (LOL) is never exceeded and the ventilation adapts accordingly.

Advanced functions
Special features on the finishing line relate to further advanced functions such as the ability to treat materials not only at temperatures of up to 320°C, but also to be able to treat the top and bottom faces of certain materials at different temperatures within a single pass through the machine.

To achieve this, the first two chambers of the stenter are fitted with special, heavy duty TwinAir ventilation motors and separate burners for individual top/bottom temperature. A temperature differential of up to 60°C can be achieved between the upper and lower nozzles within the chamber, depending on the treatment paramenters.

Another key feature of the technical textiles line at the ATC is the special stretching device which is capable of pulling ten tons in length and ten tons in width – a huge amount per square metre of fabric and necessary in the production of materials such as woven or 3D knits for high temperature filter media.

For most textiles, finishing processes are not actually the last stage. Products often need an extra touch of expertise to make them perfectly ready for the customer. At this point in the value chain, that usually means manual tasks – but now there are technical solutions and intelligent systems which can handle complex operations better, while adding extra value and assured quality.
Automation brings reliability and efficiency, ultimately saving costs to produce the right quality every time. Swiss companies are specialized in many of these disciplines, with machinery for fabric inspection and presentation, labelling and tracking, folding and packaging. They have the technology to inspire a new vision at the post-production segment of the textile manufacturing processes. Optimization of workflows, with bottleneck management, is an obvious potential benefit. And it delivers measurable returns on investment. The wider picture with automation will prepare companies for the IoT and Industry 4.0.

New business models
The advantages of automation in mills with high-volume production are obvious: consistent quality, increased efficiency, waste reduction in some cases, as well as significant medium-term cost reductions in every case.
That description focuses on the aims of modern mills in low-cost markets. But producers in Europe and USA could reach out for more. For them, automation could be a game-changer, offering unique new opportunities.
Reshoring is a growing trend now. It shows great potential and is definitely driven by sustainability and changes in consumer mindsets. “We believe that the time is right – the machines and solutions certainly are – to push automation also to the very end of the production line, replacing intensive manual work and take the chance for reshoring. The current situation is kind of a transition time which is expected to last for a couple more years in the textile industry,” says Rueedi. He adds that any investments in these prime markets pay off much faster because of higher labour costs.
Innovation transformed through automation can do much more than simply replacing the nimble fingers of humans. It also enables new business models, guaranteeing prosperous future business, alongside greater job security.

Digital workflow and process control
The Swiss company Maag Brothers is a leading supplier of high-end machines for quality assurance in the final make-up processes, specifically fabric inspection, plating/folding, selvedge printing and packaging. Maag reports on a practical example from a mill in India which recognized the potential of automation.
An analysis at the customer’s mill identified the main goals as modernization of the workflow at quality control and packing processes. Maag’s new system covers tasks from fabric inspection to dispatch, and offers transparent and easily adjustable processes with real-time process control. It’s a digital solution, resulting in a slim organization, paperless, and the basis for further optimization towards Industry 4.0 to exploit its full potential. The customer’s own calculation showed a ROI for the installation at less than three years – along with a reduction in manpower and savings in fabric costs for shade samples.

Perfectly labelled, efficient data...
Smooth processes start with a label. Swiss company Norsel is an expert in grey fabric labelling systems, for piece tracking through all textile processes. High-quality label printing and proper sealing on all kind of fabrics ensure readability and sustainability after dyehouse processes such as mercerizing, high temperature dyeing and even hot calendering. No roll mix-up during dyeing, easy sorting of fabric rolls and rapid delivery make processes in the mill much more efficient. Using RFID codes lifts fabric inventory control to the highest level, with all information readily transferred to a database and integrated through any ERP software.
It’s a foolproof way to avoid the risk of human errors from hand-written notes on grey fabrics and article sheets, by opting for reliable, secure and forward-looking solutions.

Sample collections – the silent salesmen
First impressions count, so fabric producers like to present their collection perfectly – and that’s only possible with automated solutions. Swiss producer Polytex continuously refines its solutions, underlining its leading position in sample making equipment. Fully-automatic high-performance sample production lines are designed to satisfy the highest expectations. Fully-automatic lines or robotic machines set the standards for quality and performance. Even the most demanding clients can achieve their goals with impeccable samples, quickly and efficiently made, for flawless collections that are sure to impress.

Automation drives buying
First impressions are also the trigger for quick purchase decisions. The proof is there on every store shelf. Customers of Espritech are also well aware of it. They trust this Swiss producer of automated folding machinery to provide the final touch of class to home textiles and apparel products before they go on display. The folding systems are generally large mechatronic devices, loaded with latest technologies in mechanics, electronics, sensors and pneumatics. “Textile producers are amazed how folding machines solve the tricky task of reliably handling chaotically behaving materials. They see process optimization potential and the impact. We observe a slow but continuous change of mindset installing sophisticated technology even in the last steps of textile finishing,” says Philipp Rueedi, CFO at Espritech.

Picanol has introduced its latest generation of airjet and rapier weaving machines, which have been called the “Connect” generation. These new generation weaving machines focus on connectivity and an increased level of data availability. With this new generation, Picanol is launching several new functionalities such as a digitalized Gripper stroke setting, Gripper tape monitoring, Climate control, Shed angle measurement, and fully integrated Power monitoring.

“Following the successful launch of our digital platform PicConnect earlier this month, we have now released a new generation of weaving machines, which are known as the Connect generation. Our Connect generation weaving machines can provide the correct data and are loaded with new and never-before-seen functionalities. This is clear proof that for Picanol “Driven by Data” is not just a slogan but a commitment. Not only have these innovations allowed us to make big improvements when it comes to our four design principles – Smart Performance, Sustainability Inside, Intuitive Control, and, of course, Driven by Data – but when combined with our new digital platform they will allow you to amplify your own intuition.” comments Johan Verstraete, Vice President Weaving Machines.

From now on, the range of Picanol weaving machines will have the “Connect” suffix. For the airjet weaving machines, this means: OmniPlus-i Connect and TerryPlus-i Connect, while for the rapier weaving machines, this means: OptiMax-i Connect and TerryMax-i Connect. These new machines are built around Picanol’s four main design principles:

Smart Performance
On the OptiMax-i Connect, Picanol has introduced a lubrication monitoring sensor in combination with a temperature sensor. The combined data they provide allow the user to make sure the gripper tapes are in optimal condition for maximum performance. As an option, a gripper stroke measurement sensor is also available. This not only dramatically simplifies the setting of the gripper stroke, but also enables the user to realize higher machine speeds when weaving reduced widths – a pure extra output combined with more user-friendliness.

Sustainability Inside
Even though it was 25 years ago that the Sumo Drive concept was launched, it remains the most powerful, versatile and energy friendly machine drive available. And it has been even further optimized. It features an optimized sheet metal package for lower energy consumption, optimized oil cooling circuit for a better performance and a built-in temperature monitoring. Moreover, the Connect machines can be equipped with a Power monitoring module, which allows the user to keep track of the power consumption of each machine over time. Every Connect machine also has a built-in ambient temperature and humidity sensor, which will help to optimize the climate control in the weaving shed at the lowest cost. And as raw material is the biggest cost factor, each machine can also be equipped with raw material use monitoring.

Driven by Data
As the machine has more sensors than ever before, it also generates more data. To enable a fast reaction to all these sensor data, the BlueBox control unit has been further optimized: better heat management guarantees short reaction cycles combined with the long lifetime of components. To have a good view of all of the data generated, a special sensor dashboard screen is available in the BlueTouch display: with a simple touch of the screen, the current and historical power consumption, temperature, humidity, material consumption, and – on the OmniPlus-i Connect – also the air consumption, can be monitored. The BlueTouch display is now also equipped with an Action center, an electronic logbook where all actions such as maintenance interventions can be logged or scheduled beforehand. The machine manual is now available on the BlueTouch display, and with the context-based help function the help pages related to the operation the user wants to perform appear with one touch of his/her fingertip. The built-in web browser even allows the user even to consult, for example, tutorial videos on the web to guide them through a setting procedure.

Intuitive Control
The Connect generation was designed to focus on what really matters: weave the highest possible grade A fabrics at minimal costs. A large set of tools have been installed to facilitate this goal. One of the most remarkable ones is the Harness frame stroke measurement – until recently, it was only available on the revolutionary SmartShed, but it is now also available on the cambox and dobby machines. Combined with the shed visualization and simulation, it offers a quantum leap in terms of optimizing the user’s shed settings without losing any time or taking any risks. The colors of the programmable Smart signal lights with stop timing functionality are now repeated around the push buttons, allowing even better visibility and the prioritization of interventions by the weaver. A full-fledged Access control system not only limits the access to certain pages and settings depending on the user, but also allows a tailored dashboard to be established for each user profile.

For the second time the Innovative Textile and Apparel Show opens its virtual fairground this year. For the second time, Mahlo takes the chance to get in contact with customers from all over the world. Mahlo will present the latest systems and solutions for efficient and high-quality textile production and finishing, with the focus on process optimisation in a digital environment.

In the textile industry, Mahlo is known for high-quality automatic weft straighteners, whether roller or needle straighteners, whether for the finest textiles or heavy fabrics - interested parties can find out about the right equipment for their specific requirements.

Process control systems such as the Patcontrol PCS for pattern recognition and the Famacont PMC for controlling weft and stitch course density also contribute to textile production and finishing. Mahlo wants to support manufacturers in optimising their production processes and thus also the end product in a cost-efficient way.

Solutions for technical textiles and nonwovens
Support in the production process is also available for technical textiles and nonwovens. The focus here is on the Qualiscan QMS quality measurement system. The modularly designed system, which consists of sensors and measuring frames, measures, logs and controls critical parameters such as basis weight, moisture or layer thickness across the entire fabric width. Depending on the application and task, different measuring methods are used for this purpose.

Elastics for power support in medicine and the work environment
People who do physically hard work are relieved; people who are learning how to walk again after an accident or a stroke receive support; people with a handicap gain greater mobility – exoskeletons offer valuable support in many areas. An important component for "power suits": elastics by JUMBO-Textil.

Support construction with and without drive
An exoskeleton is a kind of robot that you wear: a construction of mainly textile components that is slipped over the body and strapped on. Integrated sensors register the body movements. These impulses are converted into electrically driven movements of the exoskeleton, which support or amplify the human movement. In addition, exoskeletons without drive are also being developed: these designs aim to transfer the weight of heavy tools or loads directly into the ground.

Tough requirements, individual solutions
Since the skeletons are worn on the body, the textiles and textile components used here need to be skin-friendly and as light as possible. The body's own temperature regulating systems must not be impeded. The contact surfaces must not create pressure points. And the exoskeletons must be individually adaptable to the user's body measurements.

High-tech elastics by JUMBO-Textil offer solutions for the development of exoskeletons – in terms of functionality, safety and wearing comfort: they hold, clamp, close and secure. They relieve and cushion movements and force impact. They illuminate and forward signals. The breathable narrow textiles stretch in both directions as required. They fit snugly on the body and follow every movement. Full-surface hook-and-loop-ready elastic tapes offer a simple, secure and individually adjustable fastening option. JUMBO-Textil consistently uses components made of plastic or light metal for textile components as fastening solutions. As a solution partner for demanding tasks – e.g., in occupational safety – JUMBO-Textil also developes cooled or heated textiles in collaboration with their customers. Also possible: the development of self-luminous narrow textiles – for additional safety.

New tissue log saw allows operators to track critical component lifecycles

Paper Converting Machine Company (PCMC), part of Barry-Wehmiller, has announced that the Xcut saw, its newest tissue log saw, now has the ability to use predictive maintenance to reduce unplanned downtime.

With this new capability, operators will be able to track the lifecycles of critical components and monitor the performance of others. The saw will provide notifications regarding upcoming maintenance requirements before they become critical issues, allowing operators to have replacement parts ready when the time comes.

The Xcut saw will monitor and collect information from servo motor feedback, vibration sensors and other devices, and alert operators when the machine needs maintenance. For example, if an axis becomes more difficult to turn or experiences abnormal vibrations, the predictive maintenance system will provide an alert that the gearbox may need to be replaced.

This multifaceted approach to predictive maintenance allows operators to tackle multiple maintenance tasks at the same time, which reduces downtime and gets the machine back into production more quickly.

COBRA International is collaborating with Obodroid, a leading Thai robotics provider to help bring their novel new building security robot concept to life. With the robotic systems already in place, COBRA will deliver a set of eight composite parts that form the lightweight body shell cladding of the streamlined 1.35m high robot.

Having been involved from the very outset of the project: from the design and engineering through to the prototyping of the composite robot shell parts, COBRA will start with the production of the first batch of robots in 2020.

By using cameras and sensors integrated into robots, building operators can provide more effective and flexible security monitoring systems, providing a 24/7 autonomous patrol service around the residential area.

"Datacenter in a box" is the new powerful, flexible and secure IT infrastructure solution for the textile industry of the future

Remscheid/Berlin – Oerlikon Manmade Fibers Segment Industrie 4.0 solutions for the production of polyester, nylon and polypropylene are based on the digitalization of the production landscape and the intelligent processing of the flood of data generated in this way. In the future, the segment will offer its customers a new powerful, flexible and, above all, secure IT infrastructure. The "Datacenter in a box" was presented for the first time at the OpenStack Summit in Berlin, Germany, to a broad specialist audience. The compact datacenter works on the basis of the open operating system OpenStack, which enables virtual computing in a secure private cloud environment.

Externally, the datacenter looks unspectacular: The box contains standard hardware such as server rack, network components, batteries for reliability, monitoring sensors and a few more things. But what counts are the inner values. The Open Source software OpenStack consists of many different services and allows the virtualization of a large pool of computing, storage and network resources in a flexible, scalable private cloud. This brings two central advantages: On the one hand, virtual operation reduces costs and simplifies configuration, adaptation and expansion of the IT infrastructure today and tomorrow. On the other hand, long-cherished wishes for high data protection are fulfilled, because a private cloud maintains secure, highly encrypted data connections away from the World Wide Web.

"The functional diversity of a cloud, operation and hardware in one's own four walls at the same time – our customers immediately understood these advantages" reports Mario Arcidiacono, specialist for Business Intelligence & Data Warehouse at the Oerlikon Manmade Fibers Segment. The IT architecture also guarantees infrastructure management without downtime, the system and virus protection are automatically kept up to date at all times. Another major advantage is the scalability of the hardware and software, which can be adapted to changing requirements.

OpenStack Summit: Project example with yarn manufacturer from Vietnam presented

With these trump cards and a project example, the Group segment confidently presented itself to a genuine specialist audience in mid-November. At this year's OpenStack Summit in Berlin, where thousands of cloud professionals met, Oerlikon Manmade Fibers Segment CEO Georg Stausberg presented the customer installation at Century Synthetic Fibre Corporation, which supplies many well-known sporting goods manufacturers. The Vietnamese producer of high-quality yarns not only uses the new datacenter, but also the connection to the new "Common Service Platform (CSP)" of the Oerlikon Manmade Fibers Segment as well as an innovative new dashboard solution in prototype status. In this case, the digital instrument panel supports employee communication during shift changes in the yarn factory and introduces agile methods into the work process. The board visualizes the progress of central key figures and operating parameters from the current production process. Based on this, the employees of the successive shifts can now exchange important process and quality information and possible instructions for action within a few minutes in a structured stand-up meeting. "For the customer this means an immediate improvement of the processes, and he can significantly increase the efficiency and quality of his employees' work," assures Joerg Gross, Senior Manager in the IT-architecture team at the Oerlikon Manmade Fibers Segment.

New IT-basis for the Plant Operation Center (POC) already successful established on the market

The fixed connection to the "Common Service Platform (CSP)" of the Oerlikon Manmade Fibers Segment plays a pioneering role in such solutions. This enables services and software updates to be provided smoothly, quickly and automatically. In this way, service applications can transform collected data into instructions or automated commands to secure and improve processes. For example, the secure availability of management solutions such as the Plant Operation Center (POC) for process monitoring can be increased and possible errors can be rectified very quickly. The new digital solution AIM4DTY (AIM = Artificial Intelligence Manufacturing), which was unveiled at the ITMA ASIA + CITME 2018 in Shanghai, China, a few weeks ago, can also be implemented in this way. AIM4DTY uses methods of machine learning, determines probable causes of errors in texturing and helps to improve quality during production.

Launch at ITMA Barcelona 2019

The Oerlikon Manmade Fibers Segment offers such remote-supported services on request. Data will therefore only be transferred to the “Common Service Platform (CSP)” with the customer's consent. In addition, all data is processed in accordance with the new European General Data Protection Regulation (GDPR) and all other international data protection standards. Against this backdrop, the Oerlikon Manmade Fibers Segment plans to provide its datacenter with graded or customer-specific solutions: from complete service to provision with customer training for its own operations. After initial practical experience with several pilot customers, the segment intends to launch its offering on the market next year and officially present it to the textile industry at ITMA 2019 in Barcelona, Spain.
