Abstract
Procédé de moulage de pièces présentant une armature, notamment métallique, et au moins un élément en matériau moulable, notamment en élastomère, adhérisé sur ladite armature. On met en place dans le moule une armature préalablement déformée de façon à présenter au moins un godron, on met en place dans le moule le ou les matériaux moulables, on effectue le moulage pour adhériser le ou les matériaux moulables sur l'armature et écraser le ou les godrons de l'armature de façon que celle-ci reprenne après le moulage sa forme d'avant ladite déformation préalable. Il peut être appliqué à la réalisation de bagues d'étanchéité.A method of molding parts having a frame, in particular metal, and at least one element of moldable material, in particular of elastomer, adhered to said frame. A previously deformed frame is placed in the mold so as to present at least one gadroon, the moldable material or materials are placed in the mold, the molding is carried out to adhere the moldable material (s) to the frame and crush the gadroon (s) of the reinforcement so that the latter resumes after molding its shape before said prior deformation. It can be applied to the production of sealing rings.
