Zusammenfassung:	The invention relates to a method for overmoulding at least one seam portion (J) onto a peripheral part of a glass element (V), said seam including at least one insert (1) having an overmoulded portion comprising a sole plate (2) and a projecting portion (4) oriented along an axis (A) for pre-positioning, positioning and securing the glass element (V) in a bay to be seamed. The method is characterised in that, during injection, the insert is positioned in the moulding cavity using a pin (11) co-operating with a positioning means (5), both of which are located on the overmoulded part such that the face of the sole plate (2) turned towards the glass element includes at least one support foot (6) extending in the direction of the glass element and coming into contact therewith and the opposite face of the sole plate includes a base (3) having a free face which supports the above-mentioned projecting part (4) and which is not covered with the plastic material forming the seam. The invention is also characterised in that, during stripping, the mould is opened and the overmoulded glass panel is removed without the projecting part (4) of the insert (1) coming into contact with the wall of the housing (10). La présente invention concerne un procédé de surmoulage d'au moins une portion de joint (J) sur une partie périphérique d'un élément vitré (V), ledit joint comportant au moins un insert (1), cet insert présentant une portion surmoulée comprenant une semelle (2) et une portion saillante (4) orientée selon un axe (A) pour le prépositionnement, le positionnement ou la fixation de l'élément vitré (V) dans une baie qu'il doit fermer, ledit procédé étant caractérisé en ce que pendant l'injection l' insert est positionné dans la cavité de moulage à l'aide d'au moins une broche (11) coopérant avec un moyen de positionnement (5) situés sur ladite partie surmoulée de manière à ce que ladite semelle (2) comporte sur une face tournée vers l'élément vitré au moins une patte d'appui (6) s' étendant en direction de l'élément vitré et venant en contact avec ce dernier et sur une face opposée une embase (3) présentant une face libre supportant ladite partie saillante (4) et qui n'est pas recouverte de la matière plastique formant le joint et en ce que pendant le démoulage l'ouverture du moule et le retrait du vitrage surmoulé est opéré sans que la partie saillante (4) de l' insert (1) ne vienne en contact avec la paroi dudit logement (10).
