  • the corresponding gluing devices fall, for example, within the framework of the centering devices used beforehand for locating either the geometrical center of the spectacle lens to be treated or its optical center, the gripping block concerned then having to be arranged in a location determined in relation to one or other of these centers.
  • a sliding arm which is adapted to receive removably, the gripping block to be placed, and a carriage, on which the sliding arm is pivotally mounted between two extreme positions, one for loading and unloading, the other laying, and which, carried by a frame, is itself mounted movable between two extreme positions, one at rest, the other at the end of the race, on this frame, following a path during which the gloving arm which he wears presents himself, in the installation position, in line with a plate on which is placed on standby the spectacle lens to be treated.
  • control of the carriage carrying the sliding arm can either be carried out manually or be motorized.
  • the sliding arm is pivotally mounted in the same direction as that in which the carriage moves, with a screw-nut type engagement between it and the latter.
  • the present invention generally relates to a provision which, also capable of manual or motorized control, is advantageously free from this drawback.
  • the invention is defined by claim 1.
