Ready for take-up? Many factors in the vast field of cable and wire production can complicate the selection of the right winder. The first decision is to choose between payoff and take-up – an important distinction from the beginning. Many winders and reelers can be used both for payoff or take-up. However, the direction of rotation and control unit must be set up accordingly. Switching from take-up to payoff or vice versa is possible, but requires significant changes to the machine. The next important aspects to consider include coil size, coil weight, product properties and production speed. Not every conductor can be wound on every coil: there are physical limitations. The operator must maintain certain degrees of deflection and take into account the weight that presses down to the lowest layer. In the case of high speeds, centrifugal forces need to be calculated to keep everything under control. Rosendahl Nextrom offers a wide variety of payoffs and take-ups for different cable and wire product segments, from compact machines for small product sizes to large machines suited to heavy weights. Special winding systems are available for fibre optic products. For each Rosendahl Nextrom winder, the motor and gearbox are individually adapted to the line speed and product properties to ensure the lowest tensile fluctuations. Rosendahl Nextrom’s winders are designed for easy operation, either with or without the protective grids required by CE specifications. To create survivable identification for galvanised steel, tags have required lamination after printing in order to be able to endure every step of the process. Recognising the need to simplify this process, InfoSight – a provider of identification and traceability solutions for products and assets in harsh industrial and other extreme environments – has introduced the KettleTag® Plus EZ (patent pending). The new tag is ready to attach after printing, with no additional steps required. Fabricators and galvanisers can use InfoSight KettleTag Plus metal barcoded tags to identify fabricated products before galvanising, as they are designed to survive all nine steps of the galvanising process, as defined by the American Galvanizers Association. As this durability requires additional steps to work properly, InfoSight focused product development efforts on creating a more efficient solution: KettleTag Plus EZ. Fabricators and galvanisers can print the tag, attach it to the steel, and read the barcode on the tag after the steel has been galvanised. KettleTag Plus EZ is available in continuous feed rolls for printing on demand with InfoSight LabeLase® 1000 and 30XX printers. Tag layouts are easy to design with the free LabeLase Producer™ software. InfoSight Corp www.infosight.com A quicker, easier identification tag for galvanised steel

Each machine has its own touch terminal for operations including lifting, lowering, swivelling, bobbin selection, traverse correction and tip operation. All winders are equipped as standard with their own PLC, and various interfaces are available.

Rosendahl’s RODS 800 semi-automatic double spooler

For higher production speeds, the company recommends the use of a dancer to maintain a stable process by constantly balancing the tension. One of the latest additions to Rosendahl’s machine range is a series of semi-automatic double spoolers. These machines are particularly suitable for high-speed insulation processes up to 1,500m/min with reels of up to 2,500kg in weight. The RODS (Rosendahl Double Spooler) series covers take-up machines with a reel size of up to 800, 1,000 or 1,250mm, and can automatically change between two spools at full production speed, enabling continuous production.

The RODS double spoolers are also available as single machines.
