Abstract: The method involves calculating differences between a two-dimensional projection of a longitudinal profile of rims (11) of a spectacle frame e.g. full-rim spectacle frame (10), and a set of predetermined geometrical figures on the projection. A target geometrical figure that is closest to the longitudinal profile is selected among a set of target geometrical figures associated to trimming parameters according to the differences. A trimming setpoint is calculated according to the shape of the longitudinal profile and the trimming parameter of the selected target geometrical figure. An independent claim is also included for a method for configuring a device to prepare an ophthalmic lens.

Abstract: The method involves correcting shape of a projected longitudinal profile (52) so as to equalize perimeter length of the profile with perimeter length of an acquired longitudinal profile (50). A trimming instruction is deducted from a corrected longitudinal profile (53). The correction step is performed by stretching the longitudinal profile according to a given mathematical function, the projected profile along an ordinate axis (Y2) transverse to a horizontal axis (X2) and by compressing the stretched longitudinal profile along the horizontal axis orthogonal to the ordinate axis.

Abstract: L'invention concerne un procédé de calcul d'une consigne de détourage d'une lentille ophtalmique suivant un profil longitudinal. Selon l'invention, ce procédé comporte : - une opération d'acquisition d'un profil longitudinal initial, - une opération de centrage de ce profil longitudinal initial sur la lentille, - une opération de recherche de deux points remarquables de ce profil longitudinal initial, en fonction de critères déterminés, - une opération de calcul d'une coordonnée axiale modifiée de chaque point remarquable, en vue d'assurer un montage et un esthétisme correct de la lentille dans sa monture de lunettes, et - une opération de calcul d'un profil longitudinal final résultant d'une transformation du profil longitudinal initial qui est telle que le profil longitudinal final passe par les deux points remarquables.

Abstract: The procedure uses two moulding shells (12, 29) that are positioned at a predetermined distance from one another. The first shell (12) is fixed in a holder (6), and the second one (29) in another holder (27). The first holder is held in a position where its shell's moulding surface faces upwards and forms the bottom of a mould chamber. It is then filled with a predetermined quantity of the polymerizable material, and the second shell is moved towards the first so that its moulding surface is in contact with the polymerizable material and located partially inside the moulding chamber, at a distance from its edges.

Abstract: A method for modifying spectacle frame shape data, comprising the steps of : generating spectacle frame data by measuring the shape of a rim of a spectacle frame with a spectacle frame shape measuring apparatus, determining the principal axes of inertia of the measured shape of the rim of the spectacle frame using the rim spectacle frame data, calculating new spectacle rim frame data expressed in the principal axes of inertia of the measured shape of the rim of the spectacle frame.

Abstract: The apparatus consists of first (12) and second moulding shells with holders (6) to retain them in predetermined positions in relation to one another, and supports (1, 2) for the holders that are articulated relative to one another and can be moved between open and closed positions. In the open position the first moulding shell is filled with a predetermined quantity of a polymerizable material, and in the closed position the second shell is placed over the first to give the material the required shape for the lens. The relative movement of the supports is produced by a gear mechanism linked to a motor or a rack and power cylinder.
