摘要：To identify the mould in which a glass vessel or the like was moulded, a relief marking as moulded on the vessel, the vessel is moved relative to a reading device and is illuminated in the region of the moulded marking, and the diffraction or reflection of the light caused by the marking is evaluated, the marking consisting of two parts at opposite sides of a line oriented in the direction of movement, one part having code elements suitable for constituting at least one symbol in a digital code, and the other part containing timing marks which are provided for the purpose of generating timing impulses suitable for the sequential reading of the code elements.
