| 20090208287 | ZERO VELOCITY BEAD DISPENSER - A zero velocity bead dispenser is provided for a paint striping vehicle. The dispenser includes an electric motor which rotates a pair of rollers. A bead gun directs reflective particles into the nip point between the rollers, which discharge the particles or beads with a rearward velocity substantially matching the forward velocity of the vehicle. Therefore, the beads are discharged into the wet paint on the road with a net zero velocity so as to minimize or eliminate rolling of the beads in the paint, thereby maximizing the reflective properties of the beads. A speed sensor continuously monitors the vehicle speed and automatically adjusts the motor speed, and thus the roller speed, so as to maintain the relative zero velocity of the discharged beads. | 08-20-2009 |
