Abstract (en)
[origin: WO2015079134A1] The invention relates to a holder (1) for pneumatically blocking an optical lens (300) on a surfacing machine, comprising: - a gripping part (10) for fixing it to a corresponding member (200) of said surfacing machine, and - a part (100) for blocking said optical lens, which comprises a body (110) from which there protrude abutments which are designed to afford the optical lens a rigid seat, and a seal (170) against which the optical lens is able to be brought to bear in order to delimit with said body a vacuum chamber (180). According to the invention, said abutments comprise first rods (160) which are mounted so as to be movable in translation with respect to said body in order to bear by way of their free ends (161) against the optical lens, and provision is made of return means (179, 190) for returning said first rods against the optical lens.
