ABSTRACT:
A self propelled, walk-behind or surrey drawn striping machine includes a single fluid tank for confining and, delivering under a pressure, fluid drive, heated thermoplastic, paint and the new, environmentally preferred, thin line thermoplastic. The machine is propelled by hydraulic wheel motors. A primary material tank comprises a pressurized interior vessel that is substantially surrounded by a heating fluid circulation jacket. A third wall around the fluid circulation jacket provides a heat riser insulating space. Combustion products from a burner head below the circulation jacket rise through the insulating space. A coaxial flow channel around the conduits that deliver the striping material to a spray head carries heat transfer medium such as hot oil drawn from the heating fluid circulation jacket.
