Perfect control of the weft at all times from IRO AB

Following significant investment in the R&D capabilities at its base in Ulricehamn, Sweden, IRO AB introduced a range of new Industry 4.0-ready weft yarn feeding and tension control innovations for weaving looms at the recent ITMA 2019 in Barcelona, Spain.

IRO AB, a Vandewiele company, has been the market leader in this field for many decades, supplying systems to the majority of the leading weaving machine manufacturers, as well as advanced new products for retrofitting to working mills around the world.

The new Blue11 EasySet airjet feeder for the latest Picanol OMNIPlus Summum airjet weaving machines, for example, allows the pick length of weft yarns to be set in millimetres from the loom panel at the start-up of a new style and to be fully adjusted while the machine is running. Automatic calculations and perfect synchronization between the spool body and the oscillating fingers of the Blue 11 result in reduced and simplified settings on the weaving machine.

The new PosiFlex weft tensioner system, meanwhile, is now an integral part of the Chrono X3 weft feeder and is currently available for use on Picanol OptiMax-i rapier machines. Allowing perfectly reproducible and transferable settings for complete weft insertion cycles, it is equipped with an integrated electromagnet controlling a specially-developed and self-cleaning flex brake which ensures the correct tension at all times.

In the field of advanced tension control, the constantly-regulating new ATC-W unit has been designed for use with Luna X3, Chrono X3 and XD X3 weft feeders. It automatically maintains consistent yarn tension at a pre-determined level, unaffected by variable external factors such as bobbin size or yarn quality.

For X3 weft feeding systems, the TED is a new tension display unit that allows weft tension settings to be easily transferred from one machine to another, while the Wi-Feeder is a wireless access point for mobile phones, tablets and PCs allowing remote access to X3 feeders. The Wi-Feeder is a useful tool for troubleshooting and maintenance, providing easy access to key data during the weaving process.

The Super Elf S3 weft feeder for air and water-jet looms benefits from the latest optical sensor technology based on the principle of “signal reflection”, for reliable reading of very fine yarns down to 7 denier. It ensures accurate measurement of the weft insertion length, with a double check sensor for both Z and S winding directions. Real time control of the yarn take-off point by a reserve sensor ensures the yarn flight time is as fast and consistent as possible.

“The response to these new innovations at ITMA 2019 was much better than we expected, particularly since overall business in the weaving sector is currently going through a downturn,” said IRO AB Sales and Marketing Manager Pär Hedman. “We are now anticipating a pick-up in business as a result of the interest in our new products that was shown in Barcelona.”

IRO AB is a member of TMAS – the textile machinery association of Sweden.

Keeping products moving with Swedish automation at FILTECH 2026

At FILTECH 2026, taking place in Cologne from June 30th to July 2nd, members of TMAS – the Swedish textile machinery association – will highlight how the country’s engineering expertise is enabling filtration manufacturers to increase productivity, improve traceability and reduce dependence on labour-intensive manual processes.

Fewer pores, greater impact tolerance: Peter Dornier Foundation Prize 2026 honours material research on fibre-reinforced composite components for aerospace industry

Microscopically small pores that form during manufacture, or barely visible impact damage, can severely impair the load-bearing capacity and service life of fibre-reinforced composite components. Two young researchers have presented groundbreaking work in this field and will both be awarded the 2026 Peter Dornier Foundation Prize: Dr.-Ing. Benedikt Neitzel from the Technical University of Ilmenau for his doctoral thesis on pore minimisation in the RTM process, and Johanna Buschmann, M.Sc., for her master’s thesis, completed at the German Aerospace Centre, on the improved impact tolerance of 3D fabrics compared to 2D laminates.

Itema reaffirms its commitment to the Syrian textile industry at NasTex 2026

From July 18th to 21st, Itema will exhibit at NasTex at the Damascus Fairground (Hall 11 – Stand C02), marking its return to one of the Middle East’s historically significant textile markets. Itema will showcase advanced weaving technology designed to support the competitiveness and technological evolution of Syrian manufacturers and announces a new partnership with Growfast Agency as the sole agent of Itema in Syria.

Rieter sees Barmag integration on track as orders and sales rise

The first half of 2026 was shaped by the successful completion of the largest acquisition in Rieter’s history. The Man-Made Fiber Division enables entry into the growth segment of man-made fibers and sustainably strengthens Rieter’s market position in the Asia region. The expanded Group is now the world’s leading system supplier for the processing of natural and man-made fibers. In the first half of the year, initial cost savings in material costs and operating expenses have already been realized. The targeted synergies are expected to amount to at least CHF 20 million by the end of the 2028 financial year. Due to the completion of the acquisition on February 2, 2026, the first half of the year for the Man-Made Fiber Division only amounts to five months.
