Steel wire, cable & rod

MELC straightening method and machinery Eurobend SA first developed the hyperbolic roller rotor during the ‘80s in order to replace the conventional die rotor. The method is based on the rotor straightening system but, instead of dies, places hyperbolically profiled cylinders (rollers) made from coated steel. The cylinders execute the two fundamental operations of straightening and feeding the rod simultaneously. Eurobend has straightening and cutting machines capable of handling up to 28mm diameter products. The advantages of the method, other than straightening quality and consistency, are said to include: Minimised machine downtime, since continuous adjustment of the straightening mechanism is not needed. If a rotor operates • with the same wire diameter the average life of the rollers is believed between three and five years, depending on wire or re-bar quality and properties Straightening of high tensile steel (up to 1,800 N/mm • 2 UTS) is possible, and at a lower cost Cutting of the required length is achieved with flying shear cutter, while the wire is moving, without having to start and stop, or to • slow down the speed of the wire in order to cut

The simplicity of the design allows for the construction of multi-head machines, ie up to six rotors (straightening and cutting lines) can be fitted on a single machine body, depending on the productivity requirements and the diameter ranges of each customer. Each line works independently from the others or in any combination or all together. Each has a dedicated collector bin and can cut the same or different lengths. Applications for the system include machines processing wire, PC wire, all rebar grades, stainless steel rebar and copper coated high tensile wire for lightening rods.
