Abstract
A road finisher has a chassis and a floating laying beam, which is located behind the chassis. The beam includes a centrally divided basic beam, and extendable beams which can extend laterally from the basic beam and can be height-adjusted, with respect to the basic beam. The basic beam and the extendable beams are arranged offset one behind the other in the direction of travel. The height adjusting devices are adjusted automatically in such a way that they keep the respective rear edges of the basic beam and of the extendable beams in the same plane. A control signal for the height adjusting devices is derived from measured values for the setting angle of the basic beam. The control signal is picked up by a sensors on the front of the tie bars for measuring the distance from a reference plane independent of the road finisher, and utilized to determine the height of the rear edge of the basic beam and of the extendable extendable beams.
