Abstract
A device for fastening a holding part on an eyeglass lens placed on a plate comprises an arm adapted to receive removably the holding part and a carriage on which the arm is able to pivot between a loading and offloading position and a fitting position. The carriage is mobile on a frame between a rest position and an end of travel position over a path on which the arm is brought into alignment in the fitting position with the plate. The carriage is at least in part adapted to move in a straight line in a first direction controlled by a guide fastened to the frame and the pivot axis of the arm is in a second direction orthogonal to the first direction. A belt and gear transmission is operative between the carriage and the arm to move the arm from one end position to the other.
