Abstract

L'invention concerne une semelle modifiée pour tong ou sandale, en résine moulée par injection. On distingue une semelle, un dessous, et un dessus ayant au moins une extrémité à insérer dans la semelle. La semelle, le dessous, et l'extrémité du dessus sont réalisés de manière intégrée au moment du moulage. C'est le résultat d'une modification du moule à injection, car l'une des deux moitiés du moule comprend au moins une partie mobile. Le procédé de fabrication de la semelle repose sur l'utilisation du moule ainsi modifié.
