Abstract: A molding assembly for casting soft contact lenses especially such lenses formed of hydrophobic material. Such a molding assembly comprises a molding cavity defined by the dies of the assembly and an annular gasket or sealing member joining the peripheries thereof. The perimeter of largest diameter of the molding cavity is defined by contact between a sealing ridge which is part of the concave die or the gasket or sealing member and a bearing surface which is part of the other of the concave die or the gasket or sealing member. The annular gasket or sealing member may have an annular skirt adapted to embrace the concave die in the closed position of the assembly. The gasket or sealing member is carried by the convex die and may be integrally formed in one piece with the convex mold.

Abstract: Dispositif de moulage, pour lentille de contact souple, du genre comportant une cavité de moulage définie conjointement, d'une part par deux matrices de moulage, l'une concave, l'autre convexe, et d'autre part par un joint annulaire établissant une liaison entre celles-ci. Le bord périphérique de plus grand diamètre de la cavité de moulage est défini par le contact d'une arête de fermeture avec une surface d'appui, l'arête de fermeture appartenant à l'un quelconque des organes matrice de moulage concave-joint annulaire, tandis que la surface d'appui appartient à l'autre de ces organes. Ce dispositif est applicable, notamment, au moulage de lentilles de contact en matière souple.
