Abstract

The intermittent straightening of the wire (1) is carried out by means of a fixedly supported straightening rotor (4), the straightening blocks (5, 6, 7) of which radially deflect the wire (1) advanced by conveying mechanism (2). The mass moment of inertia of the straightening rotor (4) is dimensioned to be so small that the straightening rotor (4) can be decelerated and accelerated at least approximately within the same time period as the wire (1) by the conveying mechanism (2). For cutting to length, the straightening rotor (4) is braked in synchronism with the wire (1) and thereafter again accelerated. Thereby, a perfect wire quality is achieved, in particular a uniform elongation approximately constant over the entire length of the wire, without having to move the cutting device at the high wire feeding speed, or without having to move the straightening rotor axially or the straightening blocks radially, in order to avoid heating up and damaging of the arrested wire by the further operating straightening rotor. Different straightening rotors (4) are utilized for different wire types, these rotors being easily exchangeable with their bearings (46).
