Abstract

L'invention concerne un élément de découpe (150) pour la découpe de petites pièces découpées dans une feuille. L'élément de découpe (150) comprend un corps de base (152), qui comprend une ligne de découpe (154) sur sa face frontale (153) faisant face à la feuille et une ouverture (156) entourée par la ligne de découpe (154), l'ouverture (156) étant connectée à un puits d'aspiration (158), lequel s'étend à travers le corps de base (152) de l'élément de découpe (150), et le corps de base (152) pouvant être intégré dans une plaque de découpe (120) d'un outil de découpe (100). L'invention concerne en outre un outil de découpe (100) recevant l'élément de découpe (150) ainsi qu'un procédé pour la découpe d'utilités d'une feuille au moyen de l'outil de découpe.
