The marking head comprises a carriage movable in translation along the marking axis and along a transverse axis, which is perpendicular to the marking axis (X10). The marking head also comprises a first roller and a second roller carried by the carriage, rotatable respectively around a first axis and a second axis each located in a plane perpendicular to the marking axis. The rollers are capable of alternately marking the same article or two successive articles, depending on movements of the carriage. The invention also relates to a method for marking articles.
