ABSTRACT:
Method, applicable to two-dimensional wire bending machines for extension of their operation in bending to form three-dimensional wire frames, which is characterised by the application of a torsional moment along the axis of the wire and before the bending region, causing a permanent plastic deformation of the wire, by twisting it beyond the elastic region, with eventual result any bending action already occured in the regular plane of the two-dimensional bending macnine to be positioned a new plane, which form an angle with the regular plane equal to the remaining due to plastic deformation angle of twist.
