Abstract

Suivant ce procédé, on prévoit au moins une languette comportant une face d'extrémité à peu près perpendiculaire à la direction de séparation des parties du moule, ladite face servant à former une surface d'une rainure ou gorge à dépouille ou autre partie rentrante, on applique les parties du moule l'une sur l'autre suivant ladite direction de séparation, de telle sorte que la languette ou chaque languette vienne en contact avec l'autre des parties du moule, on amène la matière pour réaliser l'article entre les deux parties du moule et autour de ladite ou de chaque languette et l'on sépare les parties du moule de façon que la languette ou chaque languette soit retirée de l'article à travers une fente formée dans ce dernier par lesdites languettes et l'on retire l'article du moule.According to this method, at least one tongue is provided comprising an end face approximately perpendicular to the direction of separation of the parts of the mold, said face serving to form a surface of a groove or undercut or other re-entrant part, the parts of the mold are applied one on top of the other in said direction of separation, such that the tongue or each tongue comes into contact with the other of the parts of the mold, the material is brought to make the article between the two parts of the mold and around said or each tab and the parts of the mold are separated so that the tab or each tab is withdrawn from the article through a slit formed therein by said tabs and the the article is removed from the mold.
