ABSTRACT:
This invention relates to a device for straightening metal wires by means of a plurality of straightening rollers located alternately on either side of the wire, comprising a fixed chassis, a fixed carriage and mobile carriages guided on two bars parallel to the general direction of the wire. Two adjacent carriages are connected by levers assembled as scissors articulated on the carriages in the lower part and on sliding blocks guided vertically on the carriages in the upper part. A plurality of carriages and lever systems are assembled so that the distance between two adjacent carriages remains identical whatever the carriages in question during displacement of one of them. Each carriage bears one of the rollers located above the wire. Each roller located beneath the wire is borne by one of the levers, and located in an intermediate position between two adjacent upper rollers so that it moves away from said rollers and moves downwardly when the carriages are moved apart.
