Abstract

L'invention porte sur un distributeur de bande abrasive sans fin (212) comprenant un boîtier (222), un élément de retenue (224) et un élément d'actionnement (226). Le boîtier (222) est configuré pour recevoir une pluralité de bandes abrasives sans fin (14) à l'intérieur de celui-ci, la pluralité de bandes abrasives sans fin étant agencées sous la forme d'un empilement. L'élément de retenue (224) est mobile par rapport à une paroi (230) du boîtier (222) et est configuré pour maintenir l'empilement à l'intérieur du boîtier de telle sorte qu'une première bande abrasive de la pluralité de bandes abrasives sans fin de l'empilement entre sélectivement en contact avec la première paroi (230) et soit généralement alignée avec une ouverture (216) du boîtier. L'élément d'actionnement (226) est mobile par rapport à la première paroi (230) et à l'élément de retenue (224) et est configuré pour entrer en contact et déplacer sélectivement la première bande abrasive de la pluralité de bandes abrasives sans fin (14) par rapport à la première paroi (230) et à l'ouverture (216).
