Industry news Windak opens process and training centre in USA

Cable packaging machinery specialist Windak Inc has moved into its new 20,000ft 2 process and training centre in Conover, North Carolina, USA. Commenting on the move, Windak managing director Daniel Shelander said, “At the new facility we will focus on process development and customer training. To successfully provide turnkey solutions we need to engage with our customers on all levels, prior to the delivery of the equipment.” Since implementing local process and customer training, the commissioning and on-site training time have been significantly reduced. Enkotec has introduced the next generation Enkoroll – its fastest and most reliable thread rolling machine for the wire nails industry. The Enkoroll TR01, being launched in Q4 2020, has been designed to ensure that the production speed of thread rolling does not cause a bottleneck, whether in an inline or batch mode set-up. Offering an output speed of up to 3,000 nails per minute, the Enkoroll is also claimed to be equal to superior quality and consistently threaded wire nails, thanks to a highly rigid structure. With a perfectly engineered mechanical set-up and insertion mechanism, the Enkoroll enables fast and easy conversion from ring to Fuhr has developed an inline profiling system that allows manufacturers of enamelled wire to meet the high requirements of the automotive industry. The IPU320 combines rolling and profile drawing processes, so large width-to-thickness ratios can be achieved by driven rollers. One of the most important requirements during development was uninterrupted operation for months. The IPU320 is equipped with a closed control system that does not require an electrical interface to the paint spray line. The required space is kept to a minimal size of two metres; retrofitting in paint spray lines is usually possible without having to adapt the existing system.

toward future development, bringing benefits to potential and existing customers. Originating in Sweden in 1994, Windak’s first order was from Volvo, for a complete pallet-handling packaging system. The company’s technologies include high-speed rewind lines for fibre optic cable, fully automatic spooling lines, versatile coiling lines, a range of palletisers, and breakthrough coiling solutions for packaging cable products into boxes or bags. Windak OÜ www.windakgroup.com registration and event logging, Enkosmart provides tools to quickly react to errors and to carry out corrective actions. An intuitive interface for control and set-up facilitates the easy operation of the machinery and provides quick access to the features. The methodology of the development of Enkoroll with Enkosmart was to create a product that combines speed, flexibility, easy operation and quality output, merged into a digital framework to ensure maximum productivity for nail manufacturers. Enkotec A/S www.enkotec.com Due to the small layer thickness, the first calibration nozzle is only a few micrometres larger than the bare wire. If the wire does not have the correct dimensions, enamel coating might be either too thin or too thick, and insulation faults occur, which then lead to failure of the winding during operation. Another reason not to use profile drawing dies is the low degree of standardisation in transformer construction. lacquer bath and a calibration nozzle, spare lacquer is stripped off.

screw shank, providing production flexibility. An Enkotec feeder bowl, laser-cut for a smooth surface, ensures a stable and continuous flow of nails, assisted by a vibration-monitoring stabilisation feature, allowing maximum uptime by avoiding unnecessary stops. An optional automated lubrication system supports reduced labour intensity by ensuring correct and timely main- tenance of the main bearing. The new Enkoroll will also be equipped with the latest generation software platform from Enkotec – Enkosmart – which provides remote access and control for fast-track support. With supplementary features such as user Insulated copper wires are used in windings for electric motors, generators and transformers. The automotive industry’s entry into electric mobility has created new challenges for manufacturers of enamelled wire. While round wires are usually used, in large transformers (eg in power stations), enamel-insulated rectangular wires are preferred because they improve power density and efficiency. The enamel insulation is very thin, with a layer thickness of 50 to 150 μm. The lacquer is applied in ten to 20 layers, so an individual layer might be just 5 μm. As the bare wire passes a
