Bending coilers are used for torsion – free coiling of wires with dia. > 4,0 mm like cold-heading wires, non-ferrous wires and also high tensile steel wires for prestressed concrete which have to be galvanized. Bending coilers are provided for operation with single block and heavy straight-line drawing machines as well.
