METHOD AND APPARATUS FOR THE APPLICATION OF A PROTECTIVE FILM TO ONE FACE OF A SERIES OF OPHTHALMIC LENSES |
摘要 |
<p>A roll of composite tape comprising an adhesive tape and a strippable backing tape is paid out and the adhesive tape and the strippable tape are separated. A hole of predetermined diameter is punched through the strippable tape and the strippable tape and the adhesive tape are brought back together again such that a circular portion of the adhesive face of the adhesive tape remains exposed through the hole punched in the strippable tape. The exposed portion of the adhesive face of the adhesive tape is applied against a face of a lens placed on a support by displacing at least one of the support and a buffer towards each other. A cutting device is used to cut the adhesive tape around the peripheral edges of the lens and the lens is removed together with its cut-out portion of adhesive tape. The remaining portion of the adhesive tape and the punched strippable tape is also removed, and the above operations are repeated for each lens in a series of lenses.</p> |
