Abstract

L'invention concerne un article avec un corps de base élastique à base d'un vulcanisat (17) ayant une surface d'article sensible à l'usure qui est dotée d'un support textile. Le support textile, prenant en particulier la forme d'un tissage (16), d'un tricotage ou d'un maillage, présente selon l'invention une structure maillée permettant la traversée du vulcanisat (17) à la surface du textile, ce qui forme un système hybride textile-vulcanisat (15). En agissant sur le nombre de mailles, sur l'ouverture des mailles et sur la structure du fil du support textile, il est possible de contrôler la proportion de vulcanisat atteignant la surface du textile. Cet article peut en particulier être utilisé comme courroie d'entraînement. L'invention concerne en outre un procédé de fabrication d'une courroie d'entraînement dans le contexte de cette application principale.
