The invention relates to an installation for marking, at the exit of a forming machine (3), transparent or translucent objects running horizontally, in succession, in front of a marking station (7) that comprises a device (9) for producing a laser beam to ensure marking of the objects. According to the invention, the installation comprises: - means (13) for determining the position of each of the objects along at least one direction transverse to the running direction (D) of the objects, these means (13) being placed upstream of the marking station relative to the running direction, - means for displacement of the focusing plane of the laser beam, along a transverse direction relative to the running direction (D), - means (21) for driving the displacement means, connected to the determining means (13), and that make it possible to adjust, as a function of the position of each object to be marked, the focusing plane of the laser beam in order to optimize the marking of the objects by the laser beam. |
