A guide arrangement for guiding moving containers, includes at least one guide element which extends in a predefined extension direction at least in some sections along the transport path of the containers, and at least one holding device which holds the guide element at a predetermined position relative to the transport path. Start and stop timing of the output of trigger signals for the emission of pulses of an exposure beam emitted at predetermined time intervals is controlled based on the measurement value from the interferometer. One or more recesses may be positioned in an outer surface of the generally elongated member between the first and second collars.
