<p>Moulding of an optical lens from a curable synthetic material following the stages of forming the mould (13) from two shells (19A,19B) spaced within an annular closure (12); filling the cavity with mould material; assuring commencement, at least, of curing; all of which are performed in the body of the same appts. (11). The annular closure (12) consists of two jaws (12',12''), one of which is movable within a frame (19) to grip the two shells (14A,14B). An injection point (26) is machined into the lower jaw (12') to inject material at the lowest point of the cavity formed. Curing of the mould material is started at least with radiation from a radiation source through the two shells (14A,14B). Also claimed is the appts. for mfg. the optical lenses in curable synthetic material.</p> |
