    ■ une première moitié d'outil (10) et une deuxième moitié d'outil (50) mobile dans une direction de course par rapport à la première moitié d'outil, la deuxième moitié d'outil (50) pouvant être entraînée contre la première moitié d'outil (10), dans un mouvement de course oscillant au moyen d'une presse,
    ■ au moins un dispositif d'avance (20) qui est attaché à la première moitié d'outil, amène à l'outil des pièces individuelles (40) préformées attachées à une bande transporteuse perforée (42), de manière cadencée suivant une direction d'avance perpendiculaire à la direction de course, et poursuit leur transport dans l'outil, le dispositif d'avance (20) comportant un moteur électrique équipé d'un arbre d'entraînement (23),
    ■ caractérisé en ce que par l'intermédiaire d'un mécanisme à bielle l'arbre d'entraînement (23) est relié à un élément d'avance (30) qui est attaché à la première moitié d'outil et qui peut être mis en mouvement oscillant en direction d'avance et retour par le mécanisme à bielle, l'élément d'avance présentant un bec (36) s'étendant transversalement à la direction d'avance pour venir en prise dans un trou (42a) de la bande transporteuse, et
    ■ au moins la partie de l'élément d'avance à partir de laquelle s'étend le bec (36) est mobile par rapport à la première moitié d'outil à l'encontre de la force d'au moins un élément de rappel agissant parallèlement à la direction selon laquelle s'étend le bec.
  2. Outil selon la revendication 1, caractérisé en ce que le bec présente un côté avant dirigé dans la direction d'avance et un côté arrière s'étendant en biais par rapport à la direction d'avance.
  3. Outil selon l'une des revendications précédentes, caractérisé en ce que l'élément d'avance comporte un élément d'oscillation (bloc 32) raccordé à la bielle, mobile exclusivement parallèlement à la direction d'avance, et un élément de pivotement attaché à cet élément d'oscillation et portant le bec.
  4. Outil selon la revendication 3, caractérisé en ce que l'élément de pivotement est attaché pivotant à l'élément d'oscillation par l'intermédiaire d'un axe, et en ce que l'élément de rappel est un ressort.
  5. Outil selon la revendication 3 ou 4, caractérisé en ce que l'élément d'oscillation porte au moins deux éléments de pivotement.
  6. Outil selon l'une des revendications précédentes, caractérisé en ce que l'arbre d'entraînement du moteur électrique exécute un mouvement oscillant.
  7. Outil selon la revendication 6, caractérisé en ce qu'en aucune position de travail la bielle ne coupe la projection axiale de l'arbre d'entraînement du moteur électrique.
  8. Outil selon l'une des revendications précédentes, caractérisé en ce que le moteur électrique est un servomoteur.
  9. Outil selon l'une des revendications précédentes, caractérisé en ce qu'il comporte deux postes de montage où des pièces individuelles préformées sont assemblées l'une à l'autre.
  10. Installation de production constituée d'un outil selon l'une des revendications 1 à 9, et d'une presse comprenant une plaque de presse supérieure (61) qui est entraînée par un autre moteur électrique (64) et porte la deuxième moitié d'outil (50), et une plaque de presse inférieure (62) portant la première moitié d'outil (10).
  11. Installation de production selon la revendication 11, caractérisée en ce qu'il est en outre prévu une commande pour la presse, qui pilote aussi, au moins indirectement, le moteur électrique du dispositif d'avance et oeuvre ainsi pour une synchronisation entre presse (60) et dispositif d'avance.
