Abstract:
1. A paving train having an optical guidance system which is configured to produce a surface layer including concrete or asphalt material along a predetermined path, the paving train including at least one first unit including at least one first working part for carrying out a first material processing step and at least one second unit including a second working part adjustable in height for carrying out a second material processing step, the units being driven independently of one another and being capable of travelling in formation, wherein the optical guidance system comprises: at least two transmitter components provided for mounting on the second unit for transmitting optical reference beams; at least two receiver components provided for mounting on the first unit including a plurality of photosensitive receiving regions for detecting the reference beams and for determining at least one incidence position of the reference beams on the receiver component; and a computer component for deriving and providing control instructions for the first and/or second unit on the basis of the at least one incidence position in such a way that on the basis of the control instruction and by means of the at least two receiver components and of the at last two transmitter components, the first unit is guided as a function of a movement executed by the transmitter components or the second unit is guided as a function of a movement executed by the receiver components; and wherein the optical beam is a pointer for the direction of travel of the first unit, the at least two transmitter components being mounted on the second unit in such a way that it concomitantly executes the movements of the second unit.
