METHOD FOR OBTAINING AN OPTICAL LENS AND JOINT AND DEVICE FOR THE IMPLEMENTATION THEREOF |
摘要 |
The method comprises the use of a closed mould consisting of two shells (2,3) and an annular joint (4), said joint comprising a hole (19) for filling the mould cavity with a polymerizable material, the introduction of said material occurring after a stage in which an external mechanical effort is exerted in order to bring the shells (2,3) together and before a stage in which said effort is relaxed. In the joint (4), the filling hole (19) comprises two sections. A first section extends from the moulding cavity to the second section which is wider. The device comprises means (34-40) for exerting an external effort in order to bring the shells (2,3) together and means for introducing the polymerizable material into the moulding cavity. |
