d'une façon évitant tout déplacement angulaire. in a way that avoids any angular displacement.
Suivant l'invention, on parvient à ce résultat par le fait qu'il est prévu, dans la partie médiane et/ou dans les rebords, au moins un orifice en forme de fenêtre, According to the invention, this is achieved by the fact that there is provided, in the central part and / or in the edges, at least one orifice in the form of a window,

Du fait de cette mesure, il en résulte cet avantage que le point d'injection se trouve dans une position favorable du point de vue comportement du matériau polymère sur son trajet d'écoulement, de sorte, d'une part, ture of bore, it is then possible to perform the casting or injection of the polymeric material through a window-shaped orifice. Because of this measurement, this advantage results from it that the injection point is in a favorable position from the point of view of behavior of the polymer material on its flow path, so, on the one hand,

Suivant une autre particularité de l'invention, According to another feature of the invention,
