Method and device for producing a sliding rail of a longitudinal adjustment device of a vehicle seat

A method for producing a sliding rail of a longitudinal adjustment device for a vehicle seat, wherein the longitudinal adjustment device comprises at least one pair of sliding rails with sliding and/or rolling elements, the sliding rails are displaceable relative to each other in their longitudinal direction, the sliding and/or rolling elements are disposed between the sliding rails, and the sliding rails have contact tracks with which the sliding and/or rolling elements are in contact, the method comprising:

• producing the sliding rail;
• painting the sliding rail;
• subsequent to the painting step and before assembling the sliding rail with another sliding rail, irradiating with a laser at least one contact track and thereby, a paint layer situated on the contact track is removed by the laser;
• and,
• subsequent to the irradiating with a laser step and before assembling the sliding rail with another sliding rail, applying a lubricant to the contact track.
