Title: METHOD FOR OPERATING A ROAD-FINISHING MACHINE AND SCREED FOR A ROAD-FINISHING MACHINE
Abstract:
Road-finishing machines (10) have a screed (16). The screed (16) has at least one compacting element (21). The compacting element (21) is connected by means of a receptacle (27) to a connecting rod (28) that is connected to an eccentric drive (29). Road construction material is fed into the screed (16) through a gap between the compacting element (21) and a guard plate (23). This road construction material has a very adverse effect on the movement of the compacting element (21). The road construction material therefore regularly has to be removed from this region. The application creates a screed (16) and a method for operating a road-finishing machine (10) with which the road-finishing machine (10) can be operated cost-effectively. This is achieved in that at least one sensor (32) for determining a distance (37) from the guard plate (23) and/or a wiper (26) arranged on the guard plate (32) to the compacting element is associated with the compacting element (21).
