Abstract
Dispensing apparatus (2) for dispensing reflective elements, such as glass beads (4), onto a surface, typically a road surface, the apparatus (2) being attached to a vehicle. The glass beads (4) are placed in an inlet means (6) and directed along a path around a drive means (10), which drive means (10) imparts a velocity to the glass beads for subsequent delivery onto the surface through an outlet means (20). The glass beads (4) exit the outlet means (20) at a velocity having substantially the same magnitude as the magnitude of velocity at which the vehicle travels and a direction substantially opposite to the direction of travel of the vehicle.
