    摘要: Methods and apparatus for manufacturing contact lenses, including demolding contact lens mold assemblies, are described. The apparatus can include a curved wedge separator having an increasing thickness circumferentially from a leading end towards a trailing end, and an increasing radial thickness from an outer circumferential edge towards a central axis. The apparatus can also include a driver. The method can include rotating the separator around a concentric central axis and directing the separator to wedge the separator between or against one or more different mold portions of a mold assembly.

    摘要: Apparatus and methods are described for manufacturing contact lenses by forming a contact lens mold half, and removing the mold half. The mold half can then be combined with a complementary mold half and used to cast-mold a contact lens. The apparatus includes first and second plates each carrying tool halves. The plates reciprocate between an open, spaced apart configuration, and a closed configuration in which they hold complementary tool halves in contact with one another. When the plates are opened after forming a mold half, a gripper plate removes the mold half from the first plate or the second plate.
