Wire bending, straightening & forming equipment

Superior design for cold forming of metals DEM wire rolling technology is a comprehensive provider of technology for cold forming of metals. This includes the design and supply of cold rolling lines for processing steel wire rod into reinforcing wire for the construction industry. DEM has now developed and supplied high-speed lines for ribbed bars which, starting from wire rod in coils, can finish 4-16mm diameter ribbed wire in straight bars in lengths ranging from 0.9–14m, running at speeds of up to 8m/sec and collected in bundles. The superior design stands in the unbeatable straightness results and cutting precision that are achieved, despite the high speed. Bar straightness is ensured thanks to the special double straightening station. The smart design allows quick and simple set up of straightening rolls to match any production campaign. The straightening is achieved keeping the surface of the end product free of any mark and without altering its mechanical characteristics.

❍ ❍ DEM has now developed high speed lines for ribbed bars

The precise cut-to-length at high speed is granted by the DEM patented bar braking and unloading device. This system consists of a continuously rotating shear, bar deviator, braking device and double channel discharging system, all controlled by an in-house developed automation package. DEM straightening and cutting-to-length sections can also be installed on existing or newly delivered cold drawing/rolling lines for the production of coils, as additional extensions to grant the production of straight bars.
