Lämneå Bruk, a name synonymous with innovation in the wire manufacturing industry, continues to set new benchmarks with its No Twist Coiler (NTC) technology. Over three decades of relentless innovation and engineering excellence have culminated in a revolutionary product that is transforming the way spring wire is manufactured. The “NTC” technology is a game-changer, replacing traditional gooseneck and spooling methods with a unique coiling technique that promises efficiency, precision, and cost-effectiveness.

Technological benefits of the “No Twist Coiler”

At the heart of the “No Twist Coiler”s success is its ability to produce perfectly pattern-laid coils, weighing up to 4.5 metric tons, with twist-free wire. This consistency in delivering high-quality wire is achieved through a process that ensures equal back tension throughout production. For the spring wire industry, this translates into significant reductions in wire consumption per spring, offering substantial economic benefits.

The “NTC” technology’s unique package with twist-free wire in inverted carriers eliminates scrap, enhances productivity, and simplifies the shipping process. Larger wire packages reduce operational stops, thereby increasing overall efficiency. This innovation is embodied in various models, including the “NTC 500”, “NTC 750”, “NTC 1200”, “NTC 1700”, and the “NTC multi-wire take-Up”, making it versatile for post-annealing or annealing galvanizing processes.

Setting a new standard in bedding and seating wire coiling

Starting with welding wire, visionary Jonas Hagstedt, President of Lämneå Bruk, soon realized that the “NTC” had far more potential and could be extended to use with different wire types. Encouraged by the initial success, one of his customers tested the machine with spring wire. The results were even better than expected: no tangles, no scrap, and springs of consistent quality. This advanced machine sets a new standard for bedding and seating wire coiling and offers an advanced solution for spring wire producers.

The “NTC” reverses the pre-twist and the wire comes out twist-free, eliminating the need for additional straighteners. The wire drum is placed directly on the floor without rotation, uncoiling the wire over the top and guiding it through a conduit into the coiling machine. This process ensures springs of consistent and even quality at the highest standard while reducing wire consumption per spring.

The “No Twist Coiler” is engineered to meet the highest standards of the wire manufacturing industry. Its special flyer design enables coiling speeds of up to 40 meters per second, significantly increasing productivity without compromising on quality. The absence of a driven payout means no additional power consumption, further enhancing the machine's efficiency. The advanced PLC control system with an eye-level display and user-friendly operator control ensures that the “NTC” is as easy to operate as it is innovative.

Engineered for success

Lämneå Bruk’s “No Twist Coiler” is more than just an innovation; it is a revolution in the spring wire manufacturing industry. By addressing the common challenges of twist and tension, Lämneå Bruk has created a machine that not only improves efficiency and productivity but also ensures superior economic performance. With its various models tailored for different processes and its user-friendly design, the No Twist Coiler stands out as the future of wire coiling technology.
