Abstract (en)

The smoothing implement for optical lenses has a support (11) with an annular recess (15) to receive the smoothing tool (12) which is mounted by a smaller recess (16) in the floor of the main recess. The smoothing tool projects beyond the mounting. The implement has an elastic hub and projecting faces on the edges facing the smoothing tool to form an outlet orifice.

Abstract (fr)

Il s'agit d'un outil de lissage du genre comportant, d'une part, un support (11), qui est rigide, et, d'autre part, un organe de travail (12), qui est de forme générale annulaire, et qui est au moins en partie élastiquement déformable. Suivant l'invention, le support (11) forme, en creux, un logement annulaire (15), et l'organe de travail (12) est rapporté sur ce support (11) à la faveur du fond (16) de ce logement annulaire (15), en faisant cependant évidemment saillie au-delà du support (11). Application, notamment, aux lentilles ophtalmiques, qu'il s'agisse de lentilles ophtalmiques en matière minérale ou qu'il s'agisse de lentilles opthalmiques en matière organique. <IMAGE>
