Abstract

A method for manufacturing a lawn bowling ball with multiple distinct colours or finishes, comprising adding raw materials 130, 140 to a single cavity compression mould 100 divided by one or more separators 150, removing the separators 150, and stamping the raw materials 130, 140 using a plunger 120 to form a tablet 200. The method may further comprise preheating the tablet 200 to a doughy consistency, compression moulding the preheated tablet 200 to form a blank (200', fig 4), and machining the blank to form a finished lawn bowling ball (200", fig 5). Preferably the separators 150 can be removed from the mould 100 with minimal disruption to the raw materials to maintain a relatively sharp distinction between multiple colours or finishes. The separator 150 may be a planar, rigid sheet shaped to conform to the profile of the single cavity compression mould 100.
