Abstract

The specification discloses play-ball shells similar to those described in Specification 1108555, but modified in that the reinforcing filler material incorporated in the moulding ingredients comprises a finely divided cellulosic material e.g. having a particle size of up to 50 mesh in place of the thermoplastic resin disclosed in Specification 1108555. In the particular examples described, the cellulosic material comprises wood flour. The specification refers to the moulding of half-shells, which are subsequently moulded together.
