Abstract
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) comprises a device (9) for producing a laser beam to ensure marking of the objects. The installation includes a camera for determining the position of each of the objects along at least one direction transverse to the running direction (D) of the objects, the camera upstream of the marking station relative to the running direction. The focusing plane of the laser beam is displaced along a transverse direction relative to the running direction (D) with a guide driving the displacement means and connected to the camera to make it possible to adjust the focusing plane of the laser beam in order to optimize the marking of the objects by the laser beam.
