Abstract

A method and apparatus for applying a traffic stripe having improved reflectivity includes a vehicle having an apparatus for applying the traffic stripe, an applying assembly for dispersing a reflective material over the traffic stripe, another applying apparatus for applying an anti-adhesion agent, and a deformation apparatus disposed rearward thereof for forming interval grooves in the traffic stripe. The application of the anti-adhesion agent directly onto the traffic stripe or onto the deformation apparatus prevents the freshly applied traffic stripe from lifting off the road surface and adhering to the deformation apparatus.

Claims

1. In an apparatus for applying a traffic stripe including at least one vehicle and applying means for applying the traffic stripe, the improvement comprising:

first applying means for applying a reflective material over said traffic stripe;

deformation means disposed rearward of said first applying means for forming interval grooves in said traffic stripe when said deformation means passes thereover; and

second applying means for applying a predetermined quantity of an anti-adhesion agent to prevent adhesion of said applied traffic stripe onto said deformation means;

wherein said anti-adhesion agent comprises a liquid; and

wherein the predetermined quantity of said liquid sufficiently moistens a peripheral surface of said deformation means such that said reflective material adheres thereto and forms a protective layer to prevent adhesion of said applied traffic stripe onto said deformation means.

2. The improvement of claim 1 wherein said deformation means comprises a rotatable wheel.

3. The improvement of claim 2 wherein said agent applying means is positioned to apply said agent onto said rotatable wheel.

4. The improvement of claim 3 further comprising a lower agent applying means for also applying said anti-adhesion agent onto said traffic stripe.

5. The improvement of claim 1 wherein said agent applying means is positioned to apply said agent onto said traffic stripe.

6. The improvement of claim 1 wherein said traffic stripe comprises a thermoplastic line.

7. An apparatus for applying a traffic stripe to a road surface, said apparatus comprising:

a vehicle including wheels to movably support the vehicle on the ground;

an applicator attached to said vehicle for applying a traffic stripe to a road surface;

a first applying means, disposed rearward of said applicator, for applying a reflective material over said traffic stripe on the road surface;

a rotatable wheel having a plurality of spaced projections around the periphery thereof and disposed rearward of said first applying means, said rotatable wheel configured such that said spaced projections form corresponding spaced grooves in said traffic stripe when said rotatable wheel passes thereover; and

a second applying means, disposed between said first applying means and said rotatable wheel, for applying a predetermined quantity of an anti-adhesion agent to prevent adhesion of the applied said traffic stripe to said rotatable wheel when said wheel passes thereover;

wherein said anti-adhesion agent comprises a liquid;

wherein the predetermined quantity of said anti-adhesion agent sufficiently moistens a peripheral surface of said wheel such that said reflective material adheres thereto and forms a protective layer to prevent adhesion of said applied traffic stripe onto said deformation means.

8. The apparatus of claim 7 wherein said second applying means is positioned to apply said anti-adhesion agent onto said rotatable wheel.

9. The apparatus of claim 8 wherein said rotatable wheel and said second applying means are mounted on said vehicle.

10. The apparatus of claim 8 wherein said vehicle comprises a first vehicle and said rotatable wheel and said second applying means are mounted on another vehicle separate from said first vehicle.

11. The apparatus of claim 10 wherein said second applying means is mounted on the first vehicle.

12. The apparatus of claim 8 further comprising a lower agent applying means for also applying said anti-adhesion agent onto said traffic stripe.

13. The apparatus of claim 7 wherein said second applying means is positioned to apply said anti-adhesion agent onto said traffic stripe.

14. The apparatus of claim 13 wherein said rotatable wheel and said second applying means are mounted on said vehicle.

15. The apparatus of claim 14 wherein said second applying means is mounted on the first-mentioned vehicle.

16. The apparatus of claim 13 wherein said vehicle comprises a first vehicle and said rotatable wheel is mounted on another vehicle separate from said first vehicle.

17. The apparatus of claim 16 wherein said second applying means is mounted on said another vehicle.

18. The apparatus of claim 7 wherein said traffic stripe comprises a thermoplastic material, said applicator applies said traffic stripe while said thermoplastic material is hot, and said rotatable wheel forms said spaced grooves therein while said thermoplastic material is still warm.

19. The apparatus of claim 7 wherein said rotatable wheel includes a pair of spaced disks having an outer diameter slightly larger than an outer diameter of said spaced projections.

20. The apparatus of claim 7 wherein each of said spaced projections of said rotatable wheel has an outer ground engaging surface and an angled surface on either side of said ground engaging surface.

21. The apparatus of claim 20 wherein said angled surface is orientated at an angle between approximately 60°

and 45°

to said ground engaging surface.

22. In an apparatus for applying a traffic stripe including at least one vehicle and applying means for applying the traffic stripe, the improvement comprising:

applying means for applying a first reflective material over said traffic stripe;

deformation means disposed rearward of said first applying means for forming interval grooves in said traffic stripe when said deformation means passes thereover; and

applying means for applying a predetermined quantity of an anti-adhesion agent to prevent adhesion of said applied traffic stripe onto said deformation means;

wherein said anti-adhesion agent comprises a second reflective material.

23. The improvement of claim 22 wherein said deformation means comprises a rotatable wheel.

24. The improvement of claim 22 wherein said agent applying means is positioned to apply said second reflective material onto said traffic stripe.

25. The improvement of claim 22 wherein said reflective material applying means and said agent applying means are separate applicator devices.

26. The improvement of claim 22 wherein said first reflective material and said second reflective material are identical.

27. An apparatus for applying a traffic stripe to a road surface, said apparatus comprising:

a vehicle including wheels to movably support the vehicle on the ground;

an applicator attached to said vehicle for applying a traffic stripe to a road surface;

a first applying means, disposed rearward of said applicator, for applying a first reflective material over said traffic stripe on the road surface;

a rotatable wheel having a plurality of spaced projections around the periphery thereof and disposed rearward of said first applying means, said rotatable wheel configured such that said spaced projections form corresponding spaced grooves in said traffic stripe when said rotatable wheel passes thereover; and

a second applying means, disposed between said first applying means and said rotatable wheel, for applying a predetermined quantity of an anti-adhesion agent to prevent adhesion of the applied said traffic stripe to said rotatable wheel when said wheel passes thereover;

wherein said anti-adhesion agent comprises a second reflective material.

28. The apparatus of claim 27 wherein said agent applying means is positioned to apply said second reflective material onto said traffic stripe.

29. The apparatus of claim 27 wherein said reflective material applying means and said agent applying means are separate applicator devices.

30. The apparatus of claim 27 wherein said first reflective material and said second reflective material are identical.
