Roll Heads

Roll heads without drive in various designs. Production of profile wire with small or medium cross section – preferably from round wire. Roll heads are suitable for ferrous and non-ferrous metals.

Roll heads enable more economic and technically superior production compared to the use of other production techniques such as drawing with a profiled die. Optimal wire surface, lower tool wear and high degree of forming due to rolling contact between tool and wire. In special cases operation without lubrication is possible (dry operation). Roll material is matched to wire material: Tool steel, sintered metal or tungsten carbide.

Tension force is usually applied by drawing machines – alternatively by belt caterpillars. Integration in existing drawing lines as replacement of drawing die boxes without complex line modifications.

Comprehensive accessory range: Wire guides, systems for roll force measurement, central lubrication systems etc.
