Abstract

A road finishing machine comprises a screed for producing a paving layer on a subsoil on which the road finishing machine is movable in a laying direction, wherein the screed has a pulling arm fixed to the road finishing machine at a front pulling point by a levelling cylinder; at least one measuring means for performing a distance measurement, a storage means, and a controlling system. The controlling system is embodied to calculate a correction value in response to at least one distance measurement performed with respect to the subsoil and/or to a reference, which is performable at a measuring point in front of a front edge of the screed, to at least temporarily store the correction value in the storage means and calculate a desired levelling value for the measuring point taking into consideration the stored correction value, based on which the levelling cylinder of the screed is controllable.
