Abstract

Procédé perfectionné pour réaliser l'étanchéité entre des surfaces exposées à des températures élevées en opération à l'aide d'un mélange élastomère vulcanisable dont la vulcanisation est provoquée sous la pression qui s'établit au réglage de l'écartement final entre les surfaces sous l'action de la température élevée. La position finale des surfaces et par conséquent l'épaisseur du joint d'étanchéité est déterminée par des objets faisant fonction de régleurs d'écartement, disposés entre les surfaces et dont la résistance à la compression est supérieure à celle du mélange élastomère avant vulcanisation complète. Ces objets peuvent consister par exemple en billes de matières dures. Le procédé selon l'invention permet d'éviter un écrasement du joint par un serrage trop fort des surfaces.
