KARL MAYER Launches Biaxial Warp Knitting Machine Designed Specifically For The Wind Power Market

Changzhou, China – November 2026  – KARL MAYER will unveil the MULTIPLY BX, a new composite machine purpose-built for the wind power industry, at its Product Show during ITMA ASIA 2026 in Changzhou. Engineered for high speed and maximum efficiency, the machine is designed to meet surging demand in growth markets such as China, where wind turbine manufacturing continues to accelerate.

The MULTIPLY BX expands KARL MAYER's composite portfolio with a machine dedicated to the highly efficient production of biaxial non-crimp fabrics for rotor blades. It processes glass fibres with non-course-oriented weft insertion into reinforcing textiles characterised by a high proportion of filler yarns, light weft yarns, and long stitch lengths—materials essential for the unidirectional reinforcement of wind turbine blades.

"When developing the MULTIPLY BX, we consistently focused on the needs of our wind power customers. The starting point was a special fibre reinforcement fabric; the result is a highly efficient machine in its field. We look forward to presenting it during our Product Show at KARL MAYER (China) during ITMA ASIA 2026 and to a wide-ranging discussion about it," said Dr Jürgen Tröltzsch, Product Specialist for Composite Machines, KARL MAYER Technical Textiles.

With production speeds of between 1,600 and 2,200 min⁻¹, depending on stitch length, the MULTIPLY BX achieves an output of up to 500 m/h—20 to 25% more productive than the established MAX GLASS ECO. The machine performs optimally at the larger stitch lengths of 4 to 5 mm typical of this market, combining filler threads of up to 2,400 tex with light weft yarns of 100 to 200 tex to prioritise longitudinal fibre reinforcement, with a typical filler-to-weft weight ratio of 6:1.

The machine's efficiency stems from a design that pairs proven technology with targeted enhancements. While its operating concept and laying system build on the MAX GLASS ECO, the weft carriage width has been expanded to 12 inches for parallel insertion and 16 inches for cross insertion, significantly increasing output. An adjusted needle lift movement in the warp knitting zone reduces "fish eyes"—hole-shaped defects that compromise mechanical performance—while optimised lever movement minimises vibration, ensuring smoother operation, reduced wear, and improved conditions for operators.

The working width has also increased from 101 to 103 inches, enabling better material utilisation when cutting wind turbine textiles into narrow strips for further processing. Together, these improvements position the MULTIPLY BX as a specialised, cost-effective solution for producing high-performance reinforcement textiles for rotor blades.

Visitors can see the MULTIPLY BX in action at the Product Show at KARL MAYER (China) in Changzhou from 19 to 21 November, and again on 23 November 2026.
