Abstract

Pavement striping tape is drawn through a guide mounted on a rolling machine by the direct action of the front pavement roller. The tape is delivered from a spool or spools on a first spindle mounted above the tape guide and the tape backing paper is automatically withdrawn from the tape and wound up on a spool or spools on a second spindle spaced from and rotationally powered from the first spindle. Both spindles are driven by the movement of the tape downwardly due to the direct action of the front pavement roller. The striping tape is pressed by the roller into hot fresh asphalt paving material during the final rolling of the asphalt.

Claims

1. An apparatus for rolling paving material and for striping the surface of the material in a combined operation comprising a pavement roller, a striping tape supply on the roller moving therewith, a tape guide means on the roller extending between the tape supply and a point near the nip between the roller and paving material being rolled, whereby said roller can press striping tape into the paving material during the rolling thereof and the roller can draw the tape from the supply and along the guide means to said nip.

2. An apparatus as defined in claim 1, and means on the pavement roller for winding up backing material as the material is stripped from the striping tape during the feeding of the tape to said nip.

3. An apparatus as defined in claim 2, and said tape supply comprising a tape roll and a first spindle means supporting said tape roll, and said means for winding up said backing material comprising a second spindle means spaced from and parallel to said first spindle means, and means drivingly interconnecting the first and second spindle means whereby they are turned in unison by the movement of the pavement roller and without the necessity for a separate power drive.

4. An apparatus as defined in claim 1, and said striping tape supply comprising a pair of striping tape rolls and horizontal axis spindle support means for said rolls on the pavement roller, said tape guide means comprising a pair of profiled plates disposed in laterally spaced parallel relationship and fixed to the pavement roller and having lower ends terminating near and forwardly of said nip.

5. An apparatus as defined in claim 4, and plural longitudinally spaced tape guides on said profiled plates, said plates being disposed somewhat forwardly of the front roller of said pavement roller and being generally vertical and somewhat arcuate.

6. An apparatus as defined in claim 5, and said plates having lower end inclined portions projecting beneath said front roller and close to said nip, and guide wheels on said inclined portions rollingly contacting said front roller.

7. The method of claim 1, and utilizing the rolling movement of said rolling means on said paving material to pull striping tape from a supply roll of tape and feed it to the point of engagement of the rolling means with the paving material.

8. A method of applying striping tape to fresh hot asphaltic pavement during the finish rolling of the pavement in a single combined operation, comprising the steps of rolling fresh hot asphaltic paving material to produce a finished wear surface thereon, simultaneously utilizing the rolling movement of a pavement roller to continually pull pavement striping tape from a tape source, and positively guiding said striping tape during its movement from said source so that the tape is continually delivered onto the pavement immediately in advance of said roller and substantially at the nip defined between the roller and pavement.

9. The method as defined in claim 8, and the additional step of stripping backing material from said tape and collecting the backing material during the pulling of the tape from said tape source by the rolling movement of said roller.
