ABSTRACT:
A method for manufacturing hemispherical shells for covering a golf ball core, which comprises: mixing a quantity of balata sufficient to form a desired number of hemispherical shells configured and adapted for covering golf ball cores; transferring a predetermined quantity of the mixed balata to an extruder and extruding a plurality of strands of the balata at a temperature of between about 140.degree. and 280.degree. F.; cutting the strands into pellets of a desired size and injection molding the pellets into a hemispherical shell.
