Abstract

A mould is produced with the contours of a leather ball and an elastically resilient inner body placed in it with spacers to form a uniform cavity between the body and the mould walls and a specific volume of polyurethane foam reaction mixt. poured into the space. Pref. the inner body is a preinflated plastic bladder or a prefabricated polyurethane foam body of lower density than the casing.
