Machine and method for marking articles

A method for marking articles, under the action of a marking head configured to apply a marking force on an article along a first axis, the method comprising:

• loading the article in a positioning system comprising at least one carriage-turret;
• positioning the article facing the marking head via the positioning system, the article being positioned generally along a second axis oriented perpendicular to the first axis and interposed between the marking head and a support system comprising at least two rollers adapted to bear the article during marking of the article;
• marking the article by applying the marking force along the first axis on the article via the marking head;
• and
• discharging the article that is marked out of the positioning system;
• wherein the at least one carriage-turret has a degree of freedom along a direction which is parallel to the first axis during positioning and marking when the article is positioned facing the marking head;
• and
• wherein shape defects of the article are compensated by backlash means along a direction parallel to a third axis during marking of the article, the third axis oriented perpendicular to the first axis and the second axis, the backlash means equipping the support system.
