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.
Claims11
Button rod making equipment comprising:
- a. means for supplying two parts of each of a plurality of different-colored, thixotropic resins;
- b. metering pumps fed by said supply means for combining said parts of each of said resins to form accelerated resins of different colors;
- c. static, in-line mixers fed by said pumps for mixing said parts of each of said accelerated resins and for reducing the apparent viscosity of said resins;
- d. nozzle means downstream from said mixers for delivering said resins;
- e. means for repeatedly moving said nozzle means reciprocally to deposit said resins in a predetermined zig-zag pattern;
- f. a downwardly inclined trough under said nozzle means for receiving said resins in said zig-zag pattern;
- and
- g. an inclined casting tube with a closed bottom end for receiving said resins pouring from a lower end of said trough so that said resins rest in said tube at a relatively high apparent viscosity.
