摘要：
The invention relates to a device for producing a spring wire (2) comprising: a wire production apparatus (8), which is designed in such a way that a spring wire (10) can be produced from a raw material, in particular by drawing; a checking unit (14), which is designed in such a way that the spring wire (10) can be checked for flaws, in particular material flaws and surface flaws; and a laser marking unit (18), which is designed in such a way that flawed regions of the spring wire (10), in particular regions of the spring wire (10) having material flaws and surface flaws, can be marked with a laser marking (44) in such a way that a part of the surface of the spring wire (10) can be removed and that a part of the surface of the spring wire (10) can be tempered in such a way that the color of the surface of the spring wire (10) is changed in this part. The wire production apparatus (8) is designed in such a way that the spring wire (10) can be guided past the checking unit (14) and past the laser marking unit (
