A carrier () for the simultaneous measurement of sealing temperature, sealing time and sealing force in a primary packaging line for ophthalmic lenses comprises a temperature sensing plate (), a force sensing plate (), and a supporting plate (). Temperature sensing plate () is arranged atop force sensing plate (), which is arranged atop supporting plate ().

Carrier for the simultaneous measurement of a plurality of sealing parameters in a primary packaging line for ophthalmic lenses

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.

Apparatus for sealing an ophthalmic lens package

A process for the automatic manufacturing of different toric optical lenses having a front surface and a rear surface having a predetermined rotational orientation relative to one another, and with at least one of the front and rear surfaces having a toric portion, comprises forming a first toric lens by: The process further comprises subsequently forming a second toric lens different from the first toric contact lens using the same male and female mold halves () by

Process and apparatus for the automatic manufacturing of different toric optical lenses

A printing station for producing a layer of coloring for a contact lens, comprising a transport system to carry and transport a molding tool which comprises at least one contact lens forming mold, a pad unit comprising at least one pad, and a blade unit suitable to carry and ink a clich&#xe9; with an ink. When in use the pad transfers an inked image from the clich&#xe9; to the contact lens forming mold. The printing station further at least partially cures the inked image after it has been transferred to the mold and cleans the pad.

Printing apparatus for making colored contact lenses

A method comprises the steps of (a) providing a water based ink in at least one clich&#xe9; with a contact lens pattern; (b) transferring the water based ink from the clich&#xe9; to at least a surface of at least a contact lens forming mold by means of at least a transfer pad; (c) at least partially curing the ink transferred on the mold to form a colored film; (d) dispensing a hydrogel lens-forming material into a lens-forming cavity of the mold; and (e) curing the lens-forming material within the lens-forming cavity to form the contact lens, whereby the colored film detaches from the molding surface and becomes integral with the body of the contact lens; characterized in that the relative air humidity in the immediate vicinities of the transfer pad/s is kept higher than 50% at standard temperature and pressure conditions during ink transfer.
