Abstract: Il s'agit de contrôler l'adéquation à une monture de lunettes d'un verre (10) à meuler. Suivant l'invention, ce contrôle d'adéquation se fait sur la meuleuse (11) elle-même, en montant le verre (10) à meuler sur sa broche de support (15), en amenant ce verre (10) au contact de la meule (12) en l'absence de toute rotation de celle-ci, en faisant tourner pas à pas la broche de support (15) jusqu'à ce que le verre (10) à meuler fasse sur lui-même un tour complet, et en contrôlant si, au cours de ce tour, le détecteur de contact (17) associé au gabarit (16) est actionné par celui-ci. Application aux meuleuses mises en œuvre pour le débordage d'un verre de lunettes.

Abstract: This involves checking the fitting of a lens (10) to be ground, to a spectacles frame. According to the invention, this fit check is done on the grinding machine (11) itself, by mounting the lens (10) to be ground on its support spindle (15), bringing this lens (10) into contact with the grinding wheel (12) without this grinding wheel rotating at all, causing the support spindle (15) to rotate step by step until the lens (10) to be ground makes a complete revolution on itself and checking whether, during this revolution, the contact detector (17) associated with the template (jig) (16), is actuated by this lens. Application to grinding machines used for trimming the edges of a lens for spectacles.

Abstract: The invention relates to a contour reading apparatus of the type comprising, for holding the article whose contour is to be read, two jaws (14A, 14B), at least one of which can be moved with respect to the other. According to the invention, at least one of the jaws (14A, 14B) supports, locally on its face (22) pointing towards the other jaw, at least one tactile sensor (24) for guiding the mobile jaw (14A, 14B). Application in particular to reading the contour of the rims or surround of a spectacles frame.

Abstract: The invention concerns a device in which a blocking arm (13) is mounted on a carriage (15) in such a way that it pivots between a raised loading position and a pivoted fitting position. According to the invention, between the blocking arm (13) and the carriage (15) there are pawl-type engagement means (38, 40) capable of a releasable locking of this blocking arm (13) on this carriage (15) when it is in the pivoted fitting position. Application to the blocking of any grasping stud on a spectacle lens workpiece.
