  • Patent number: 6752568
    Abstract: A device for placing individual road markers in desired configurations along a road surface comprises an application wheel having at least one aperture connected to a frame by an axle. The frame and application wheel are then connected to a trailer that is pulled along behind a pulling device. The apertures of the application wheel are dimensioned to receive a part of the road marker in a position tangential to the surface of the application wheel. As the application wheel rolls over the surface, the base portion of the marker contacts the road surface. An adhesive portion of the marker causes the base of the marker to become adhered to the road surface. As the application wheel continues to roll, the standing reflective portion of the marker is withdrawn from its position within aperture of the application wheel, and remains in a desired location upon the road surface.
