From the Sector

KM.ON launches its new Quality Monitoring System (QMS) for the retrofit market at ITM from June 4 to 8 in Istanbul, presenting a solution for quality management on warp knitting machines.
For its performance in defect detection, the QMS uses the advances of our time: a camera system that captures images of the production process, and a specialized artificial intelligence (AI) to analyze the images. Particularly in terms of handling, reliability and precision of defect detection, the QMS from KM.ON offers advantages over conventional systems that do not rely on AI analysis.

The QMS is designed for easy setup and can be operated without prior expertise. If a defect causes the machine to come to a standstill, the operator is informed immediately via a user-friendly interface. The immediate warning enables rapid intervention and therefore less downtime and more productivity.

Thanks to its conceptual design, the QMS only stops production when actual defects are detected. Unnecessary interruptions caused by external disruptive factors, such as changing light conditions, are avoided. This precision prevents productivity losses and helps to ensure continuous operation. Costs due to unnecessary machine downtime are avoided.

Unlike conventional camera systems, the QMS detects even the most complex defects and triggers an immediate machine stop. This minimizes material waste. During operation, the AI-controlled system learns from the data to enhance its detection accuracy, thereby reducing the reject rate and costs. The QMS also adapts to evolving production environments to ensure consistently high efficiency.

Breaking new ground in plastics recycling means assessing the value chain from end to end. The big opportunities for the future are in fine-tuning the individual process steps; from the collection of recyclable materials to the recycling process and the end product. This is where the cooperation of Lindner and the EREMA Group comes in, officially launched following the 50/50 founding of the holding BLUEONE Solutions in August 2023 to which shares of Lindner Washtech were contributed. The expertise of EREMA, a manufacturer of extruders and filtration solutions for plastics recycling and the largest company within the EREMA Group, has now been combined with the expert know-how from Lindner Washtech, a leading provider of all-in-one solutions for shredding, sorting and washing plastic feed materials.

Data transfer ensures more efficient recycling processes
Process control is an especially important aspect of plastics recycling, which is why standardising the process control system was what the two companies focused on first. "Together, we have developed a platform that allows data to be exchanged between the extruder and the washing system," says Manfred Hackl, CEO of the EREMA Group at IFAT in Munich. "This enables us to analyse the data more precisely so that effective improvement measures can be deduced." All key parameters are taken into account and monitored via a digital interface. For example, it is possible to use information relating to the current throughput of the EREMA Pre Conditioning Unit to optimise the washing process as soon as possible so that it can compensate for fluctuations in capacity and achieve a significant increase in output. This data transfer represents a new step on the roadmap to digitalization.

High efficiency due to smart energy management
"To ensure sustainable recycling, it is necessary to find the right process for each application and to make sure that the individual process steps are perfectly coordinated," emphasizes Michael Lackner, Managing Director of Lindner. Coordinating the process steps has already achieved initial success in energy management, and a clear example of this is heat recovery. "We use the latent heat generated during the extrusion process as an energy source for the washing and drying process," explains Lackner. "This enables our customers to sustainably reduce their energy costs and carbon emissions".

Making the most of synergies along the value chain
Synergies need to be used to establish the quality standards specified for each end application. "The key question is how we can improve the end product and increase the overall efficiency of the recycling process at the same time," agree Manfred Hackl and Michael Lackner. This will only work if companies work together along the value chain. The industry leaders can already point to several examples where together they have improved recycling processes and made it possible to move away from downcycling. "An example of this is the recycling loop of HDPE starting material, which is processed into high-quality, food-safe rHDPE pellets using our two technologies," says Lackner. Lindner Washtech and EREMA continue to work intensively together to develop strategies for upcycling plastics and increase recycling rates.

Monforts, which is celebrating its 140th anniversary this year, will exhibit a Montex stenter chamber with an integrated overhead heat recovery unit at the forthcoming ITM textile machinery exhibition in Istanbul from June 4-8.

The heat recovery unit on display at the stand of Monforts partner Neotek is just one of a range of energy saving options the company is now providing for both new and existing line installations.

Monforts Montex stenters and Thermex dyeing ranges are industry standard for the fabric finishing industry, providing many advantages in terms of production throughput and especially in energy efficiency and savings.

coaTTex
At ITM, Monforts will also introduce its latest coaTTex coating unit, dedicated to air knife and knife-over-roller coating. For single-sided application with paste or foam, the versatile coaTTex is suitable for both incorporation into existing finishing ranges as well as installation with new Monforts lines, especially Montex stenter systems.

A wide range of coatings can be applied to fabrics for providing functions such as waterproofing, liquid and gas protection and breathability, in addition to foam lamination and coating, including black-out coating.

Central location
“In Turkey we are very strongly supported by our representative Neotek, our solution partner on the ground for service, installation and commissioning, providing specialised and rapid help to all of our customers,” says Monforts Area Sales Manager Thomas Paeffgen. “ITM is always one of the most important exhibitions for Monforts, for meeting customers not just from Turkey, but across the Middle East and Central Asia, as well as Bangladesh, India and Pakistan.

“Istanbul’s centralised position makes it accessible to the majority of the major textile manufacturing hubs and as we mark our 140th anniversary in 2024, having been founded back in 1884, the ITM show will provide us with the ideal opportunity to celebrate with colleagues and customers all together in one location.”

Cavitec, part of Santex Rimar Group, presents the redesigned Caviscreen at Techtextil Frankfurt. Caviscreen features latest technology for breathable laminates.

Caviscreen was developed as a hotmelt coating and laminating unit for breathable sportswear, rainwear and protective clothing – with and without applying a membrane. The redesigned machine shows a brand-new method to supply adhesive more evenly and precisely. Using PUR adhesive (polyurethane reactive adhesive) goes with additional benefits like strong bonding capabilities and versatility.

Caviscreen’s hotmelt screen printing is a special system for high-end application garments. With this Caviscreen system, a PUR adhesive is transferred onto the substrate through a rotary screen, similar to the well-established textile printing method. The adhesives are fed from the drum melter through a heated hose to the traversing adhesive distribution system inside the rotary screen, just behind the doctor blade.

The adhesive is pressed by the doctor blade through the screen holes and transferred to the substrate. Different dot pattern (mesh or irregularly) and different screen thicknesses allow different coating weight and adhesive coverages.

The traversing adhesive dispenser is used to distribute the adhesive automatically over the set working width that – an additional technical benefit – can be set without any mechanical changes.

Cavitec’s screen coating system achieves high bonding strength while using less adhesive than other coating processes, because of applying the coating on the surface of the substrate and like this, the adhesive has less tendency to penetrate the substrate.

Bonding strength, softness of the fabric and the breathability are defined by the coating weight and the coverage. The rotary screen allows users to regulate and adapt the coverage respectively the coating weight. Cavitec offers a large selection of screens that are essential to fulfil the fabric requirements. A further advantage is the ease and efficiency of switching from one screen to another by simply unlocking the bayonet fitting. The IR-heater cover opens pneumatically and the lightweight screen can be easily removed by hand. Unlike with other methods, there's no need to deal with hot oil or any other heated liquid that requires cooling down.

The Caviscreen technology supports manufacturers by reducing costs with screens priced at a mere fraction, just 10%, of common gravure roller prices.

On March 6, 2024, Rieter received an order for the first batch of Rieter technology amounting to around CHF 62 million from Shanghai Digital Intelligence World Industrial Technology Group Co., Ltd. (DIW). Rieter also signed a strategic partnership with DIW to develop an intelligent yarn manufacturing technology that utilizes digitization and automation to minimize conversion costs.

Rieter and DIW signed a first order in the amount of around CHF 62 million for combers and draw frames that will provide the basis to transform DIW’s spinning mills into state-of-the-art industrial textile operations. DIW, a fast-growing company specializing in intelligent manufacturing and industrial operation services, selected Rieter following a competition in which the company’s machines achieved better stability and higher production than competitors. The strategic partnership of DIW and Rieter is designed to further enhance the overall operational efficiency of DIW’s mills by providing highly efficient machines, automation and digitization technology. This will also minimize conversion cost and consolidate the sustainable growth of both companies, while contributing to the high-quality development of the Chinese textile industry.

Mahlo GmbH + Co. KG will participate in the Colombiatex textile show, held in Medellin from 23 to 25 January. This year, Mahlo will be joining forces with Brückner Textile Technologies to present their solutions for the textile production sector at their joint booth.

Both companies appreciate the power of Colombia’s textile industry. Textile is one of the most important industrial sectors in the Latin American country with an export value of clothing of more than 600 million US dollars. The United States are also the main export destination for apparel products. At Colombiatex 2024, Mahlo's Head of Sales, Thomas Höpfl, will be present to share insights and discuss how Mahlo’s innovative technologies can address the specific challenges faced by Colombian textile manufacturers. Sustainability of process efficiency being among the most pressing ones.

Together with the German circular knitting machine builder Mayer & Cie., Groz-Beckert has developed the optimized Relanit sinker SNK F over the past years. Independently of this, the development of the new LCmax™ energy-saving needles took place. The focus of both developments is on efficiency, energy savings and increased process reliability.

Groz-Beckert offers interested machine builders different cooperation options to jointly develop new products or optimize existing ones. The Groz-Beckert Technology and Development Center (TEZ) provides the appropriate framework for so-called co-development projects. At the ITMA in Milan in June 2023, Groz-Beckert presented some of the successful cooperations under the motto "Innovation through cooperation". Among them were two new developments realized with Mayer & Cie. Groz-Beckert presented the two new products for the first time in Asia at ITMA Asia in November 2023.

Optimized Relanit sinker SNK F
At the end of 2018, circular knitting machine manufacturer Mayer & Cie. approached Groz-Beckert with a request to jointly develop an improved and more efficient sinker for selected machines of their Relanit family that would run more smoothly and reliably in the needle tricks. The innovative sinker has an integral spring with a spring force that is adapted to the sinker thickness. Field tests were consistently successful and confirmed the functionality and advantages of the new sinker.

Thanks to their adapted spring, the newly developed SNK F Relanit sinkers are securely guided while they are running through the cam track, resulting in a quieter operation. This increases process reliability and ensures an improved loop structure. In addition, wear on the swivel butts of the sinkers is reduced. This increases service life and makes the process more sustainable and cost-efficient.

Higher energy efficiency thanks to LCmax™
The objective second recent cooperation with Mayer & Cie. was to develop a cost-effective energy-saving needle. After considering various variants, the common choice of Mayer & Cie. and Groz-Beckert was the LCmax™ knitting machine needle with innovative, wave-shaped shank geometry. The first prototypes were extensively tested on laboratory machines at Groz-Beckert's TEZ.

The wave-shaped shank of the LCmax™ needle ensures a smaller contact area of the needle in the needle trick. This results in less friction, which reduces machine temperature and enables energy savings of up to 20 percent compared to a standard needle. This saves costs and at the same time allows operation of the machine at the maximum possible speed.

In both projects, the cooperation between Mayer & Cie. and Groz-Beckert went far beyond mere product development. In addition to Applications Engineering and Construction, the companies' Sales and Purchasing departments were also involved in a close exchange.

Rieter’s cumulative sales in the first nine months of 2023 amounted to CHF 1 092.9 million (2022: CHF 987.4 million), an increase of 11% compared to the prior-year period. In particular, supply bottlenecks eased slightly, which allowed more machines to be delivered than in the same period last year. Sales in the third quarter of 2023
were CHF 334.7 million (Q3 2022: CHF 366.8 million).

The Business Group Machines & Systems generated total sales of CHF 749.6 million in the first nine months of 2023 (+18%). The Business Group Components posted sales of CHF 206.8 million, 11% lower than in the corresponding period of the previous year, while the Business Group After Sales recorded growth of 13% to CHF 136.5 million in the first nine months of 2023.

Order intake in the reporting period was characterized by restrained investment in new machinery in almost all regions except China. Demand for consumables, wear & tear and spare parts continued to weaken due to the slowdown in spinning mill capacity utilization. Rising interest rates and high energy and raw material prices also had a dampening effect.

In this market environment, the Rieter Group received orders totaling CHF 452.2 million in the first nine months of 2023 (2022: CHF 1 095.8 million). In the third quarter of 2023, orders decreased by 44% year-on-year to CHF 127.2 million (2022: CHF 226.4 million).

Rieter expects the market to have bottomed out in the year 2023 and anticipates a gradual market recovery in the course of the 2024 financial year.

As of September 30, 2023, Rieter has an order backlog of around CHF 900 million (September 30, 2022: CHF 2 000 million). The current order backlog will allow good capacity utilization at the production facilities into the coming year. The cancellation rate in the reporting period was within the usual range, averaging around 5% of the order backlog, with a slight downward trend.

In July 2023, the Group launched the “Next Level” performance program aimed at strengthening sales excellence, sharpening customer focus, improving cost efficiency in production and optimizing fixed cost structures. By taking these measures, Rieter intends to create the basis for providing an even more agile response to the cyclical nature of the machinery business. The objective of the planned initiatives is to ensure the profitable and sustainable development of the group.

The performance program includes provisions for the net reduction of approximately 300 positions in overhead functions across the group, primarily in Germany and Switzerland. The consultation processes initiated with the employee representatives in Ingolstadt (Germany) and Winterthur (Switzerland) were completed in the third quarter of 2023. The majority of these workforce reductions are expected to be implemented by the end of December 2023.

Due to the current market situation, further market- and volume-related adjustments in the range of 400 to 600 positions will be necessary, mainly in production. However, the actual number of positions to be reduced depends on the order intake in the coming months.

Rieter continues to expect that the strategic and operational measures initiated will result in one-off restructuring costs of around CHF 45 to 50 million, which will impact earnings in the 2023 financial year.

Outlook for the full year 2023 confirmed
As announced on July 20, 2023, in view of the economic situation and the ongoing cyclical market weakness, Rieter continues to expect below-average demand for new equipment in the coming months. A revival is not anticipated until the end of 2023 at the earliest. Likewise, Rieter believes that demand for consumables, wear & tear and spare parts will not recover until towards the end of 2023.

For the full year 2023, Rieter expects an EBIT margin of around 5 to 7% (including positive special effects of less than 2%) and sales at the previous year’s level of around CHF 1.5 billion.

At this year’s Techtextil India, the Polymer Processing Solutions Division of the Swiss Oerlikon group will be presenting the trade audience with new applications, special processes and sustainable solutions focusing on the production of industrial textiles. Between September 9 and 12, the discussions at Jio World Convention Centre (JWCC), Mumbai, will be concentrating on airbags, seat belts, tire cord, geotextiles, filter nonwovens and their diverse applications.

More polyester for airbags
The yarns used in airbags are made predominantly from polyamide. As a result of increasingly diverse airbag applications and also the increasing size of the systems used, polyester is today used as well, depending on the application requirements and cost-benefit considerations. Against this background, the Oerlikon Barmag technol-ogies make an invaluable contribution. In addition to high productivity and low energy consumption, they particularly excel in terms of their stable production processes. Furthermore, they comply with every high quality standard for airbags, which – as in the case of virtually all other textile products used in vehicle construction – must provide the highest level of safety for vehicle occupants - without any loss of function in any climate and for the lifetime of the vehicle

Buckle up!
Seat belts have to withstand tensile forces in excess of three tons and simultaneously stretch in a controlled manner in emergencies in order to reduce the load in the event of impact. A seat belt comprises approximately 300 filament yarns, whose individual, high-tenacity yarn threads are spun from around 100 individual filaments. “With our unique, patented Single Filament Layer Technology, we offer a sophisticated and simultaneously gentle high-tenacity (HT) yarn process for manufacturing these lifesavers and other applications made from industrial yarn”, explains André Wissenberg, Head of Marketing.

Road reinforcement using geotextiles
Low stretch, ultra-high tenacity, high rigidity – industrial yarns offer outstanding properties for the demand-ing tasks carried out by geotextiles; for instance, as geogrids in the base course system under asphalt. Normally, geotextiles have extremely high yarn titers of up to 24,000 denier. Oerlikon Barmag system concepts simultaneously manufacture three filament yarns of 6,000 denier each. Due to the high spinning titers, fewer yarns can be plied together to the required geo-yarn titer in a more cost- and energy-efficient manner.

hycuTEC –  quantum leap for filter media
In the case of its hycuTEC hydro-charging solution, Oerlikon Neumag offers a new technology for charging nonwovens that increases filter efficiency to more than 99.99%. For meltblown producers, this means material savings of 30% with significantly superior filter performance. For end users, the consequence is noticeably improved comfort resulting from significantly reduced breathing resistance. With its considerably lower water and energy consumption, this new development is also a future-proof, sustainable technology.
