layout. Another milestone came in 1956, when engineers were able to make hot formers for manufacturing ball bearing races. Carlo Salvi started production of at die thread rollers in the 1940s. In 1952, the company introduced its rst single-die double-blow header. In the 1970s, it produced a line of headers for the production of semi-tubular or fully tubular parts. The rst single-die double-blow header equipped with linear wire feed, quick-change kit and electronic interface was launched in 1999. Hatebur Umformmaschinen AG www.hatebur.com Locating breakdowns in kilometres of medium- and high-voltage cables has traditionally been carried out o ine after disruption has occurred. However, that makes measurement labour- and time-intensive, as extensive investigations are often required to nd the breakdown. As a result, Highvolt developed a new measuring device that nds breakdowns quickly and simply. The HiRES Locator is a solution not only for grid operators and power utilities that have to monitor increasingly complex cable systems, but also for cable manufacturers, who can bene t from adding the device into their test procedures for quality assurance. in ongoing operation, a digital recorder is connected to the cable to locate breakdowns immediately as they occur. The measuring principle is based on the pulse re ectometry method, also known as TDR (time domain re ectometry). Previously, measurement engineers have had to generate an arti cial breakdown signal when trying to nd faults. This electric pulse spreads throughout the conductor as a travelling wave. When the wave encounters a material change, it is re ected back, and the location of the breakdown is calculated based on the time di erence between the signal being sent and being received. The HiRES Locator can perform this procedure in real-time. For example, it has been used to identify faults in cable joints during factory and commissioning tests.

Swiss metal forming expert Hatebur will showcase its solutions at wire, presenting four key group technologies: servo transfer unit, servo-electric wire feed, servo direct drive and Hatebur Connect. Visitors will also be able to view a new Carlo Salvi machine at the Hatebur stand. The merger of Hatebur and Carlo Salvi in 2016 brought together the skills and knowledge of two companies in the cold and hot forming sectors. A servo-electric driven transfer unit will be displayed. Besides the transfer unit itself, each of the grippers is also driven by a servo motor and can be individually adjusted for opening and closing, bringing advantages when it comes to changeover times. The servo-electric linear wire feed system ensures that the material in-feed is precise, with a volume variation of less than 0.3 per cent.

The HiRES Probe remote measuring sensor is a new addition to the HiRES range. With its shielding properties, the design of the component ensures high-precision results, even in environments with strong electromagnetic interference like high-voltage laboratories. Data is transferred optically to the evaluating unit, which boosts the measurement accuracy, as do the 250 MS/s sampling rate, 14 bit resolution and 100 MHz analogue bandwidth. The ability to use the HiRES Probe in battery mode enables autonomous operation without grid power and allows measurements on high voltage potential. software facilitates test sequence automation, as well as o ering fully automatic logging of measurement results. The compact HiRES Probe can be used in tight spaces (such as in the base frame of a measurement divider), o ering users greater exibility.

The linear in-feed requires no wire stop, which eliminates the occurrence of contact marks; changeover is quick, and maintenance is easy. The servo direct drive allows control of the movement of the press ram detached from the transfer unit and the versatility of the die and punch ejectors, o ering new elds of applications. With Hatebur Connect, the company is equipped for the future. Hatebur CEO Thomas Christo el explained, “All the relevant systems within the machines are connected and can communicate, which o ers new opportunities for the analysis, data collection, machine status monitoring, preventive maintenance and the overall optimisation of productivity.” Hatebur’s history started with the invention of the turret-type forging press in 1930. In 1950, the company pioneered the rst fully automatic three-die progressive header with horizontal tool ▲ The servo-electric linear wire feed system ensures that the material in-feed is precise
