Claim:
1. A system for pelletizing road marking material, comprising: a mixing section configured to mix thermoplastic binder, filler, and pigment materials suitable to form a dry mixture for formulating a thermoplastic road marking substance, said dry mixture comprising glass beads; a melting section positioned downstream from the mixing section and configured for heating the dry mixture to a pre-determined degree sufficient to melt the dry mixture and form a homogenous binder-filler-pigment melted thermoplastic road marking substance containing glass beads; a pelletizing section configured to receive the melted thermoplastic road marking substance and cool the melted thermoplastic road marking substance while forming a plurality of individual solid pellets of the thermoplastic road marking substance containing glass beads, the pelletizing section comprising a form belt conveyor provided with a plurality of spaced-apart form pockets, and wherein the melted thermoplastic road marking substance of road marking substance is deposited into the form pockets, as the melted thermoplastic road marking substance exits a dispensing conduit of the melting section; a spreader extending transversely to path of the form belt conveyor, positioned adjacent an idler pulley of the form belt conveyor and immediately adjacent the dispensing conduit, and running along top of the form pockets and is configured to evenly distribute the melted thermoplastic road marking substance in the form pockets; and a packing section configured to package the solid pellets of the thermoplastic road marking substance into shipping containers.
