Four-head taping machine for magnet wires The sector of flat magnet wires for the production of transformers and generators is constantly evolving, with producers of taped cables increasing quality levels and technical performance. This requires machinery manufacturers to work on increasing the performance of taping machines specific to this process, to produce cables that meet the final request. claimed to be the first taping machine on the market capable of working at high performance with four mutually synchronised taping units, equipped with concentric taping heads suitable for both tape spools and pads. This is the third generation of WTM machines suitable for the The cameras are

The taping heads rotate at 2,000 rpm, fully synchronised through the control cameras (though limited to 1,500 rpm when the fourth head is enabled). The mutual overlapping of the tapes has a tolerance of the mutual position lower than 0.5mm. automatically programmed by the machine Motion Control System, so no specific operator training on the Visio System is required. The entire process is fully automated, even during start/stop and machine stringing phases. The layout of the magnet cable-taping machine is composed of: • traversing payoff with wire tension managed by torque control • straightening and brushing unit for wire preparation • taping modules with fully motorised taping heads, equipped with WTM dynamic dancer to ensure stable and constant application of the tape on the conductor • Visio System and control software for adjusting the position of each tape with respect to the previous one • two-caterpillar pulling system to control line speed and cable tension • spark tester for in-line control of product quality • take-up with cable tension managed by torque control, and wire guide with traversing movement • paper feeder, installed on the take-up, to automatically apply a layer of paper on the reel during the winding of the final cable WTM www.wtmachinery.com

synchronisation of multiple concentric taping heads dedicated to this particular product. With mechanical, electrical and software improvements, the cable taping line almost doubles the speed compared to the previous machine versions, and increases the productivity. The synchronisation of the taping heads is managed by WTM’s Visio System, a fully integrated control system equipped with high-speed cameras that continuously monitor and adjust – in closed-loop control – the positioning of the tape applied by a taping head with respect to the tape positioned by the previous one.

The study of the taping process for magnet cables has highlighted the importance of increasing both quality and production efficiency. While keeping the guarantee of mutual overlapping of each tape, this translates into a refinement of the process, an accurate choice of components and synchronisation of each element. WTM’s improved solution dedicated to magnet cables is equipped with specific hardware and software for the control of the mutual overlapping of up to four different tapes taken from spools. It is
