ABSTRACT:
A moderately resilient, energy-absorbing practice golf ball and a process for manufacturing same are disclosed, the ball having a dense metal core surrounded with a thick layer of resilient material. To this, a fabric cover able to carry marking powder is bound. The practice ball leaves powder marks at its points of impact, and has a substantially reduced velocity upon rebound. The process of manufacturing the practice ball includes the steps of binding dense metal shot or granules together with resilient adhesive to form a core, wrapping uncured rubber strips into a thick layer around the core, pressing the surface of the layer to make it spherical; pressing a layer of textile fabric into the surface of the uncured rubber, curing the ball with elevated temperature and pressure to fuse its layers together and abrading the ball's fabric surface to raise a powder-carrying nap.
