Abstract

Device for scrubbing a metal wire, including means for feeding and running the wire (F), at least two pairs of rotary brushes ( 21, 22 ) having a radius r, the axes of which are substantially mutually parallel and perpendicular to the direction in which the wire runs, application means, suitable for contacting the brushes with the wire via the circumferences thereof in order to exert a given pressure on the wire (F) while the device is operating, and means ( 31, 32 ) of adjusting the tension of the wire are provided directly upstream and downstream of the assembly of brushes.

First claim

The invention claimed is:

1. A device for scrubbing a metal wire, comprising:
a means for feeding and running the wire;
at least two pairs of circular brushes, each circular brush being mounted for rotation about an axis, the axes of circular brushes being substantially mutually parallel and perpendicular to a direction in which the wire runs;
an application means, suitable for causing a circumference of the rotating circular brushes to contact the wire under pressure while the device is operating; and
a tension adjusting means for adjusting tension of the wire as the wire passes between the two pairs of circular brushes comprising at least two transport rollers driven in rotation by motors associated with a means for controlling the torque and speed of the at least two transport rollers, one transport roller being positioned upstream of the two pairs of circular brushes, and one transport roller being positioned downstream of the two pairs of circular brushes.

2. The device according to claim 1 , wherein the wire runs in a rectilinear manner between the at least two transport rollers.

3. The device according to claim 1 , wherein the circular brushes of a pair of circular brushes are capable of rotating at an identical speed and in opposite directions.

4. The device according to claim 1 , wherein the axes of the circular brushes of each pair of circular brushes are situated in a plane perpendicular to the direction in which the wire runs.

5. The device according to claim 1 , wherein the axes of the circular brushes of each pair of circular brushes are offset in relation to each other relative to a plane perpendicular to the direction in which the wire runs by a given length.

6. The device according to claim 1 , wherein a tangential speed of the circular brushes of a pair of circular brushes at a point of contact of the circumference of the circular brushes with the wire is in a direction opposite to the direction in which the wire runs.

7. The device according to claim 1 , further comprising:
an enclosure in which the at least two pairs of circular brushes are positioned; and
a means for circulating forced air in the enclosure.
