Abstract
A surface marking devices for heating and applying thermoplastic material. The surface marking device is comprised of laterally disposed oil-jacketed melting kettles having a rotatable auger extending from a first end to a second end; the first end having an open inlet for receipt of particulate thermoplastic marking material in a non-molten state. The second end coupled to a thermo pump for transfer of the thermoplastic marking material in a molten state to a sprayer, extrusion die, or an auxiliary vehicle for subsequent application. Retro-reflective glass beads can be added to the molten state during the spraying step.
Claims9
A surface marking device for applying thermoplastic marking materials to a surface comprising:
- at least one laterally disposed oil-jacketed melting kettle having a rotatable auger extending from a first end to a second end, said first end having an open inlet for receipt of non-molten particulate thermoplastic marking material, said second end fluidly connected to a discharge;
- a heating mechanism for heating said laterally disposed oil-jacketed melting kettle, said heating mechanism constructed and arranged to melting said thermoplastic marking material placed therein to a temperature suitable for transfer as molten thermoplastic from said discharge.
The surface marking device for applying thermoplastic marking materials to a surface comprising:
- a self propelled vehicle having a chassis;
- a plurality of laterally disposed oil-jacketed melting kettles secured to said chassis, each said kettle having a rotatable auger extending from a first end to a second end;
- a platform positioned over said melting kettles;
- an open inlet along a first end of said kettle accessible through said platform for receipt of non-molten particulate thermoplastic marking material, said second end of each said kettle fluidly connected to a discharge;
- a heating mechanism attached to said vehicle for heating said laterally disposed oil-jacketed melting kettles, said heating mechanism constructed and arranged to melt said thermoplastic marking material placed therein to a temperature suitable for transfer as molten thermoplastic from said discharge.
