ABSTRACT:
A method is disclosed for applying rather viscous line marking material to road surfaces whereby simultaneously with the manufacturing of marking strips in the same continuous motion crossribs from the same material are shaped on the marking strips. The marking material flows out through a slit between the back edge of the bottom side and the lower edge of the back wall of a storage box, a periodical up- and down movement being imparted to this back wall for shaping the ribs, preferably by means of fast upward driving impulses each of one followed up by a separate downward driving impulse. Preferably the material is forced to flow out substantially in a direction at an angle of at least 30.degree. to the direction of movement of the storage box and the trailing end thereof is kept in engagement with the road surface.
