The vertex of the interior angles is bevelled, with assigned rake and bevel angles of the rotary tool, by moving the tool parallel to the bisector of said angle, firstly on one side and then on the other side of the bisector, with the active part of the tool substantially tangential to the bisector. The apparatus comprises at least one rotary tool (such as a grinding wheel), drive means for rotating the tool, first means for supporting the tool and the drive means in such a manner as to enable them to be moved angularly within a first vertical plane about a diameter of the tool, second means for supporting the first means in such a manner as to enable them to be moved angularly within a second vertical plane perpendicular to the first, and means for supporting said second means in such a manner as to enable them to be moved in three mutually perpendicular directions and rotated about one of said directions. The product is a sheet of coloured or non-coloured plain glass, plate glass or flattened glass with at least one bevelled interior angle.
Le sommet d'un angle intérieur est biseauté au moyen d'un outil rotatif à angle de coupe et angle de biseau donnés en déplaçant l'outil parallèlement à la bissectrice dudit angle, d'abord d'un côté de la bissectrice puis de l'autre, la partie active de l'outil étant sensiblement tangente à ladite bissectrice. La machine comprend au moins un outil rotatif (une meule par exemple), un moyen d'entraînement dudit outil rotatif, un premier support de l'outil et du moyen d'entraînement permettant de les déplacer à angle dans un premier plan vertical tangent à l'outil, un second support adapté pour soutenir le premier support de façon à permettre un déplacement de l'ensemble à angle dans un second plan vertical perpendiculaire au premier et un support adapté pour soutenir le second support de manière que l'ensemble puisse être déplacé selon trois axes mutuellement perpendiculaires et mis en rotation autour d'un desdits axes. Le produit obtenu est une plaque de verre uni, de verre à glace ou de verre laminé coloré ou non et présentant au moins un angle intérieur biseauté.
