Abstract

Extruded rubber or plastics strip moulded into hemispherical female dies by displaceable male die members or punches is folded or brought together with a similar strip so that two hemispherical dies are coincident and join by reason of their hot and tacky state. The spheres or balls are cured and finished. They may be hollow or contain cores or fillings.
