ABSTRACT:
The invention relates to a road-finishing machine with a laying beam (2) which is provided with control members (8) for adjusting the height and inclination of the laying beam (2) as well as measuring sensors for this purpose, the output signals of the measuring sensors serving as actual values for adjusters (10, 11) controlling the control members (8) in accordance with desired values which can be predetermined. In order to be able to automatically maintain transverse inclination values according to a predetermined profile plan, it is provided that a path measurement device (12) is provided, the output signals of which can be fed to an onboard computer (14), the onboard computer (14) being provided along the laying path with a data store (17) for storing the length of a transitional section and the differential value of the transverse inclination, which differential value is to be maintained between the starting and finishing point of the transitional section, and it being possible for the desired values, which can be predetermined and are calculated by the onboard computer (14) for the inclination adjuster (11), to be altered continually by the onboard computer (14) depending on the road surface from the starting to the finishing point.
