  • Patent number: 5674347
    Abstract: An apparatus for the processing and segmenting of a cover-forming laminate web or sheeting structure which is adapted to interconnect a plurality of containers, such as the base members of blister packages each of which is designed to contain a hydrophilic contact lens in a sterile aqueous solution. More specifically disclosed is an apparatus for the imprinting, perforating, slitting and cutting the laminated web structure such that the severed laminate segments constitute printed covering label for an array of such containers, and whereby the laminated web or sheeting segment may be severed along weakening or perforation lines so as to provide a separable packaging arrangement for individual of the containers which are subsequently adhered thereto.
    Type: Grant

  • Patent number: 5658602
    Abstract: An apparatus for forming contact lenses, wherein front curve mold halves are filled with a hardenable transparent material, such as a polymerizable hydrogel, and back curve mold halves are coupled to the front curve, therein forming a lens. More particularly, the apparatus includes a conveyor for transporting pallets of mold halves to the apparatus, an array of piston structures for raising and aligning the back curves with respect to the filled front curve halves, a mechanism for reciprocating the piston array to couple pairs of front and back curves, and a vacuum chamber for maintaining a vacuum around the curves during coupling. In addition, there is provided individual spring biasing to each reciprocating element whereby sensitivity to thickness variations and pallet misfeeds may be minimized. Further, there is provided a vacuum sleeve, through which the pistons reciprocate within the vacuum chamber, which sleeve preserves the vacuum within the chamber.

  • Patent number: 5656208
    Abstract: An apparatus for filling and assembling mold parts for a contact lens includes a first automated station for receiving a plurality of front curve contact lens mold parts and depositing in each front curve mold a predetermined amount of a polymerizable monomer or monomer mixture, and, a second automated station for receiving the plurality of front curve mold parts and assembling each front curve mold part with a back curve mold part under vacuum to prevent entrapment of gas between the mold parts. The front curve mold parts are transported to the first and to the second automated stations by a pallet having registration guides that cooperate with the second station to register the pallet prior to assembly of the mold parts.

  • Patent number: 5640980
    Abstract: An automated means for hydrating a molded hydrophilic contact lens is provided in which a first robotic assembly removes a plurality of contact lens molds from a production line carrier, each of the lens molds having a contact lens adhered therein. The first robotic assembly transports the molds to a first staging area where the lens molds are sandwiched between a lens mold carrier and a top chamber plate to form a first hydration carrier. A first rotary transfer device then hands the first hydration carrier to a second robotic assembly which immerses the first hydration carrier in a hydration bath to hydrate the lens and to release the lens from the lens mold. While the lens is immersed in the hydration bath, each lens is transferred from its respective mold to a lens transfer means found within the top chamber plate.
