  • Patent number: 4162862
    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from a spool or spools on a first spindle mounted above the tape guide and the tape backing paper is automatically withdrawn from the tape and wound up on a spool or spools on a second spindle spaced from and rotationally powered from the first spindle.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.
