Coiling technology from Sweden Lämneå Bruk has been working on the No Twist Coiler (NTC) technology for more than three decades. NTC can transform wire manufacturing by replacing traditional gooseneck and spooling technologies. multiple carriers. This method maximises efficiency and minimises downtime, ena bling continuous coil-to-coil operation. The inverted carrier payoff system also reduces power consumption compared to traditional set-ups.

The innovative machine produces coils up to 4.5 metric tons with straight and twist-free wire in inverted carriers. Every metre of the wire can be run, resulting in no scrap, for maximum productivity. The larger wire package has the advantage of fewer stops during operation, and offers convenient shipping options. This new wire package in carriers unlocks various non-stop payout benefits. The streamlined approach integrates advanced technology into operations, starting with the elimination of driven or non-driven payoffs. Instead, wire drums are placed directly onto the floor, complemented by the NTC reversing pre-twist technology, ensuring a straightforward production process. Uninterrupted workflow is achieved by welding finish ends to start ends of

The NTC technology ensures equal back tension throughout the entire production process. This precision is especially valuable in spring wire production, where reductions in wire consumption can be achieved. When used in line with the drawing machine, the key advantage is the unlimited speed capability of the coiler. The drawing line speed can be increased as the coiler runs at unlimited speed; the drawing machine is the limiting factor in this scenario. The straightforward cast and helix set-up ensures operator friendliness as well as quicker changing times for enhanced productivity. Lämneå Bruk’s NTC portfolio currently comprises several machines: the NTC 500, 750, 1200 and 1700, as well as the NTC Multi-Wire Take-Up, suitable for
