PRECAST CONCRETE ELEMENTS152 CPI %u2013 Concrete Plant International %u2013 5 | 2025 www.cpi-worldwide.comAs the inventor of the hyperbolic roller rotor, Eurobend GmbH sets a new milestone with the new, maintenance-free fifth generation straightening rotor.The heart of the rotor straightening machines of Eurobend GmbH are the latest 5G rotors. They ensure excellent straightening quality, with a straightening accuracy of better than 1/1000. Even with highly ductile material, such as ductility class \material properties are unaffected (preserved) and the reinforcing steel ribs are protected. The patented, fully automatic rotor maintenance system minimizes operator intervention:%u2022 Minimize of machine downtime, as maintenance and readjustments of the long-life hyperbolic straightening rollers, compared to conventional systems with straightening dies, are not required.%u2022 The Eurobend straightening machines consume over 40% less energy than similar machines using rotors with straightening dies.%u2022 Perfect straightening even of high tensile concrete steels.%u2022 The different rotor sizes and types cover diameters up to %u00d825 mm and a wide range of wire qualities.%u2022 The simplicity of the design allows the construction of multi-line machines according to the productivity requirements and the diameter ranges to be processed.%u2022 Waste reduction by exploiting the last length of each coil thanks to the last piece extraction system.%u2022 Production data is processed using common industry formats such as Unitechnik, BVBS, etc. Software updates and rapid remote diagnostics can be performed via the Internet.By combining (with) a number of other innovations, machines are offered to meet any customer-specific production requirement:MELC Monoline Series %u2013 Single Rotor StraightenersA range of machine versions processing rebar diameters up to 25mm.
