Abstract
A reflective bead dispenser for use with an airless paint spray gun for marking traffic lines on pavement surfaces is connected to the spray gun by supporting a hollow tube in a passage through a handle of the gun. An inlet end to the tube is connected with a supply of reflective beads, an outlet end from the tube has a nozzle for dispensing reflective beads into a spray of paint emitted from the gun, and a valve controls a flow of beads through the tube. The beads are entrained in the paint spray and deposited along with the paint on the pavement surface to form a reflective stripe thereon.
