Abstract
In moulding a ball consisting of a cover on a hard spherical core, e.g. a base ball, or a golf ball, one of the problems is maintaining accurate location of the core in the ball. According to the invention the core is surrounded by a moulded shell having co-spherical projections which support the ball in a spherical mould in which the cover is moulded on. The shell may be of two half shells clipped together.
