Abstract: An apparatus for thermally bonding together a cover film of an ophthalmic lens package and a base part of the package, including a carrier for supporting the base part with film arranged thereon; a bonding unit above the carrier having a mounting plate with a bonding stamp extending therefrom, the bonding stamp having a mounting portion fixedly attached to the mounting plate, a bonding head arranged beneath the mounting portion with a heatable bonding contour on a side of the bonding head facing the carrier, and an articulated connector arranged between and connecting the mounting portion and the bonding head; and an actuator for performing movement of the carrier and the bonding stamp towards and away from each other for thermally bonding the film with the base part by pressing the heated bonding contour against the film and subsequent separation of the bonding head from the cover film bonded to the base part, the articulated connector being a cardanic joint with two rotational axes.

Abstract: A method of cleaning deposited material from a molding surface (10) of a mold (1) for forming ophthalmic lenses, including bringing a cleaning head (20) into contact with the molding surface (10), the rotational axis (22) of the cleaning head (20) being arranged normal to the molding surface (10), rotating (220) the cleaning head (20) around the rotational axis (22) while maintaining the contact between the cleaning head (20) and the molding surface (10), moving the cleaning head (20) to perform a precession motion (110) around a central normal (11) on the molding surface (10), while rotating (220) the cleaning head (20) around the rotational axis (22) and while maintaining the contact between the cleaning head (20) and the molding surface (10). During the precession motion (110) the rotational axis (22) includes an inclination angle (?1,?2) with the central normal (11) on the molding surface (10).

Abstract: There is described a method for the simultaneous manufacture of contact lenses having different lens parameters on the same production line, where a number of molds, each comprising male and female mold halves, are transported in sequential rows of and in each row in side by side configuration through a series of treatment stations, which are arranged sequentially along a production line, in which lenses of specific parameters are manufactured from a lens forming material. During manufacture each lens is associated with a lens identification code. There is also described a closed cycle production line for carrying out the method.
