Abstract
A thermoplastic extrusion vehicle for continuous processing of thermoplastic material used for applying lines and stripes to a roadway. Heated oil from a burner is directed to a common reservoir having a section for oil distributed to the extremities of the vehicle and a main section for heating of melting kettles; the common reservoir having a divider wall capable of maintaining two different temperatures within the reservoir. A programmable logic controller displays and records the mil thickness of lines that is calculated according to the volume of material consumed at the rate of application based upon the speed of the vehicle.
