ABSTRACT:
Button rods are made of different colored resins containing thixotropic agents and having catalyst and promoter agents added to separated portions of each resin so that when the resins are combined their gel time is accelerated. The combined resins are mixed both for mixing purposes and to lower the apparent viscosity, and the resins are fed through nozzles and into an inclined trough. The nozzles are reciprocated in arcs to lay the resins in a zig zag pattern in the trough, and the resins flow from the trough into an inclined casting tube where they quickly attain a relatively high apparent viscosity until they are removed from the tube before completely hard. The rods can then be sliced into button blanks or hardened and ground into beads.
