Claims (12)

  1. Dispositif d'entaillage et coupe destiné à découper des matières d'emballage (9) comprenant une matrice (1) et une partie de lame qui présente au moins deux lames (2) reliées à une plaque porte-outils (4 ; 104), la matrice (1) et la partie de lame pouvant se déplacer l'une par rapport à l'autre pour effectuer une coupe, caractérisé en ce qu'au moins une des lames (2) prévues dans la partie de lame est reliée à la plaque porte-outils (4 ; 104) d'une façon qui dépend de la force par l'intermédiaire d'un coussin de gaz, de telle manière que sa position par rapport à la plaque porte-outils (4 ; 104) varie d'une façon définie en fonction de la force qui résulte d'un contact avec une matière d'emballage (9) ou avec la matrice (1).
  2. Dispositif d'entaillage et coupe selon la revendication 1, caractérisé en ce qu'il est configuré et commandé de manière que, lors de l'exécution d'une coupe effectuée par rapprochement mutuel de la partie de lame et de la matrice (1), l'au moins une lame (2) disposée d'une façon qui dépend de la force entre en contact avec la matrice (1).
  3. Dispositif d'entaillage et coupe selon la revendication 1 ou 2, caractérisé en ce que chacune des lames (2) prévues dans la partie de lame qui entrent en contact avec la matrice (1) lors de l'exécution d'une coupe est montée sur la plaque porte-outils (4 ; 104) d'une façon qui dépend de la force, individuellement ou ensemble avec d'autres lames (2), par groupes, par l'intermédiaire d'un coussin de gaz, de telle manière que sa position par rapport à la plaque porte-outils (4 ; 104) varie d'une façon définie en fonction de la force qui résulte d'un contact avec une matière d'emballage (9) ou avec la matrice (1).
  4. Dispositif d'entaillage et coupe selon une des revendications 1 à 3, caractérisé en ce qu'il présente des moyens pour la fixation d'une force maximale qui n'est pas dépassée par la force agissant sur la lame (2) dans le cas d'un contact entre la lame (2) et la matrice (1).
  5. Dispositif d'entaillage et coupe selon une des revendications 1 à 4, caractérisé en ce qu'il est configuré et commandé de telle manière que, lors de l'exécution d'une coupe effectuée par rapprochement mutuel de la partie de lame et de la matrice (1), il s'exerce sur les lames (2) une force qui est au maximum de 1000 N par mm de longueur de lame, de préférence de 10-100 N par mm de longueur de lame et par mm d'épaisseur de la matière d'emballage (9) à couper.
  6. Dispositif d'entaillage et coupe selon une des revendications 1 à 5, caractérisé en ce que les dispositions des différentes lames (2) dans la partie de lame peuvent être permutées entre une position de coupe et une position d'entaillage, une lame (2) placée dans la position de coupe découpant entièrement la matière d'emballage (9) disposée entre la lame (2) et la matrice (1) lors de l'exécution d'une coupe, tandis qu'une lame (2) placée dans la position d'entaillage ne fait qu'entailler la matière d'emballage (9) disposée entre la lame (2) et la matrice (1).
  7. Dispositif d'entaillage et coupe selon une des revendications 1 à 6, caractérisé en ce qu'il est prévu des moyens (24 ; 124) pour introduire du gaz dans le coussin de gaz et pour l'en évacuer, qui permettent de fixer la relation de dépendance entre la position de la lame (2) par rapport à la plaque porte-outils (4 ; 104) et la force qui agit sur la lame (2).
  8. Dispositif d'entaillage et coupe selon une des revendications 1 à 7, caractérisé en ce qu'au moins une des lames (2) prévues dans la partie de lame est disposée de manière à pouvoir reculer en fonction de la force, de telle manière qu'elle conserve sa position dans le cas d'une charge qui est plus petite qu'une force limite, et qu'elle recule dans le cas d'une charge qui est plus grande que cette force limite.
  9. Dispositif d'entaillage et coupe selon une des revendications 6 à 8, caractérisé en ce que, pour chaque lame prévue dans la partie de lame, il est prévu une butée (25 ; 332) de préférence réglable, contre laquelle la lame (2) s'appuie directement ou indirectement dans la position d'entaillage lors de l'exécution d'une coupe.
  10. Dispositif d'entaillage et coupe selon une des revendications 1 à 9, caractérisé en ce qu'il est prévu pour chaque lame (2) prévue dans la partie de lame, une butée (332) de préférence réglable, contre laquelle la lame (2) s'appuie directement ou indirectement lors de l'exécution d'une partie d'une coupe dans laquelle une force de coupe comparativement plus grande est nécessaire, tandis qu'elle en est espacée dans la partie suivante, restante, de la coupe, dans laquelle une force de coupe comparativement plus petite est nécessaire.
  11. Dispositif d'entaillage et coupe selon une des revendications 1 à 10, caractérisé en ce que la partie de lame est fixe en position et la matrice (1) peut être rapprochée de la partie de lame, la partie de lame présentant des raclettes (5) montées élastiquement qui sont serrées par la matrice (1) et par la matière d'emballage découpée (9) lors de l'exécution d'une coupe et qui raclent la matière d'emballage (9) sur les lames (2), lorsque la matrice (1) s'éloigne de la partie de lame.
  12. Dispositif d'entaillage et coupe selon une des revendications 1 à 11, caractérisé en ce qu'en plus des lames (2), sont disposés en supplément sur la partie de lame des poinçons (3) en supplément qui poinçonnent chacun un trou dans la matière d'emballage (9) lors de l'exécution d'une coupe.
