Title (EN) A BALL AND A METHOD OF MANUFACTURING A BALL
(FR) BALLE ET PROCEDE DE FABRICATION D'UNE BALLE
Abstract:
(EN) A ball has a wall of elastomeric material defining a cavity. The cavity contains a filling which comprises a plurality of substantially closed cells. The pressure in the cavity is substantially atmospheric pressure. The substantially closed cells fill a peripheral part of the cavity adjoining the inner side of the wall, or the cavity is substantially filled with the substantially closed cells. The substantially closed cells have elastomeric walls. At least some of the substantially closed cells are separate hollow bodies. The hollow bodies are microspheres.
(FR) La présente invention concerne une balle dont la paroi en matériau élastomère définit une cavité. Cette cavité contient un matériau de remplissage constitué d'une pluralité de cellules sensiblement closes. La pression intérieure de la cavité est sensiblement la pression atmosphérique. Les cellules sensiblement closes remplissent une zone périphérique de la cavité jouxtant la face intérieure de la paroi. Mais cette cavité peut également être sensiblement remplie de telles cellules sensiblement closes. Les parois de ces cellules sensiblement closes sont en élastomère. Certaines au moins des cellules sensiblement closes sont des corps creux distincts. Les corps creux sont des microsphères.
