The present invention provides a method of making a rubber track having fibrous reinforcement, said track having predefined holes for studs wherein the holes are formed during the vulcanisation of the track. Preferably, the method comprises preparing a layered mould whereby the adjacent surfaces of the mould contain opposed male and female formations and then vulcanising the track by pressing the mould together such that the male formations in the mould pass through the track to produce holes in the track.
Méthode de fabrication de courroies porteuses pour motoneiges. Les courroies sont constituées de caoutchouc renforcé de fibres et comportent des orifices à des endroits prédéterminés pour recevoir des crampons, ces orifices étant formés pendant la vulcanisation de la courroie. De préférence, la méthode comprend les étapes suivantes : préparer un moule sandwich dont les surfaces opposées présentent des formations mâles et femelles opposées; vulcaniser la courroie en la pressant entre les parties du moule de manière que les formations mâles du moule traversent la courroie pour la trouer.
