Abstract
1,047,203. Moulding balls. H. MEYER. May 8, 1963, No. 9432/63. Heading B8A. [Also in Division A6] Balls of different diameters are made by making them of different wall thickness but constant inner or outer diameter and then inflating them to the desired diameter. As shown in Fig. 1, a constant outer mould 1 is used with one of three inner moulds. The moulding material is first placed in the mould 1 and then the inner mould pressed down into it. Conical parts 12, 13 locate the moulds with respect to each other. Escape passages may be provided for excess material. In a modification (Fig. 4, not shown) the material may be injected into the mould. An inflation passage may be formed in the ball by a mandrel 17, Fig. 6. Several balls may be formed simultaneously.
