Abstract

A method for forming a tablet suitable for preparing a blank for a lawn bowling ball having multiple distinct colours or finishes, comprises adding raw materials to a single cavity compression mould, divided between separate compartments temporary defined within the single cavity compression mould by one or more separator assemblies, and stamping the raw materials within the single cavity compression mould to form a tablet suitable for forming a blank for a lawn bowling ball, following removal of the one or more separator assemblies prior to stamping.
