ABSTRACT:
A glue dispenser is mountable on a vehicle as part of apparatus for installing raised road markers on a roadway. Preferably, the apparatus is used in a system for automated installation of road markers. The dispenser includes a manifold having an inlet for glue fed downwardly into the manifold from a glue reservoir mounted on the vehicle. First and second glue outlets communicate with the inlet. First and second valves control opening and closing of the first and second outlets, respectively. The valves are operable both simultaneously and independently of each other to permit glue to be dispensed from only of the outlets or from both of the outlets simultaneously, as needed. The outlets are spaced apart a distance equal to a desired distance between lines of markers in a double line installation.
