Abstract

L'invention se rapporte à un procédé de fabrication d'objets à base de caoutchouc, aux moyens pour sa mise en oeuvre et aux objets eux-mêmes. L'invention vise plus particulièrement un procédé de fabrication d'ébauches et de semi-produits à base de caoutchouc caractérisé en ce qu'il a recours, d'une part, en tout ou partie, à du caoutchouc accéléré, mais non vulcanisé, et, d'autre part, au formage par injection, en conservant les propriétés de plasticité et le pouvoir collant du caoutchouc, après démoulage et avant toute vulcanisation L'invention s'applique, d'une manière générale, aux industries de transformation du caoutchouc.
