More particularly, this invention relates in one aspect to a resilient waterproof boot, or glove which is formed in one piece, can be fitted over a human foot or hand without a zipper and is useful for aquatic activities. A process of manufacturing a seamless resilient article which comprises: (a) heating a mold in the shape of the article to an elevated temperature; (b) immersing the mold in a first elastomer dispersion and partially curing the coating of the elastomer; (c) immersing the mold and the first elastomer coating in a second elastomer dispersion and partially curing the coatings of the elastomer; and (d) removing the article from the mold.

L'invention se rapporte à un article imperméable, élastique et sans coutures pouvant être porté par une personne. En particulier, l'invention se rapporte, selon un aspect, à une botte ou un gant imperméable et élastique, en une seule pièce, qui peut s'adapter sur le pied ou la main d'une personne sans fermeture éclair, et qui convient à des activités aquatiques. Un procédé de fabrication d'un article élastique sans coutures consiste à: (a) chauffer un moule présentant la même forme que l'article jusqu'à une température élevée; (b) immerger le moule dans une première dispersion d'élastomère et faire durcir en partie la couche d'élastomère; (c) immerger le moule et la première couche d'élastomère dans une seconde dispersion d'élastomère et faire durcir en partie les couches de l'élastomère; et (d) enlever l'article du moule.
