Abstract
A drawing and/or straightening unit for feeding one or more oblong metal products to a machine for working the metal products is included that has a first roller on which at least one metal product being fed is positioned longitudinally. Also included is a second contrasting roller, opposite the first roller. This keeps the metal product correctly positioned during feed. The drawing and/or straightening unit has actuators operationally associated with the second roller to initially move and position the second roller with respect to the first roller and to vary the distance between the rollers. The actuators have actuators for initial movement of the second roller to the first roller, and for selective and controlled movement of the second roller.
