Patent ID: 7458243

Claim:
A spring winding machine ( 1 ) for manufacturing springs ( 15 ), comprising a wire conveying device ( 5 ) and a wire shaping installation ( 7 ), including at least one diameter control tool ( 11 a ) and at least one pitch control tool ( 11 b ), which wire shaping installation is controllable by a machine control ( 3 ), for selectively controlling movement of at least one of said wire shaping installation tools ( 11 a , 11 b ), characterized in that at least one measuring sensor ( 27 ) of a measurement device ( 25 ) is arranged upstream of the wire shaping installation with respect to the conveying direction of the wire to be shaped, and that at least one of the said pitch and diameter control tools ( 11 a , 11 b ) of the wire shaping installation ( 7 ) is responsive in its movement to impedances or measured variables influenced by induction or eddy currents detected by the upstream measuring sensor ( 27 ).
