Procédé d'entraînement d'une unité d'impression, avec au moins un cylindre de contre-pression (03) et un cylindre (04) formant avec celui-ci un emplacement d'impression (01), les deux cylindres (03 ; 04), coopérant et se trouvant en contact de pression, pouvant pendant la production être entraînés avec des vitesses périphériques (u03 ; u04) différentes l'une de l'autre à l'emplacement d'emprise, caractérisé en ce qu'un réglage des différentes vitesses périphériques (u03 ; u04), pendant la production, s'effectue par l'intermédiaire d'au moins une transmission électronique (G) à rapport de transmission variable, associée à un moteur d'entraînement (06 ; 07) d'un des deux cylindres (03 ; 04).
  2. Procédé selon la revendication 1, caractérisé en ce que le réglage du rapport de transmission s'effectue à la transmission électronique (G) d'un moteur d'entraînement (06 ; 07) au reste régulé quant à sa position angulaire en rotation.
  3. Procédé selon la revendication 2, caractérisé en ce que, au moyen de la transmission électronique (G), une vitesse de rotation et/ou une position angulaire en rotation du moteur d'entraînement (06 ; 07) est/sont modifiée(s) de la valeur d'un facteur susceptible d'être présélectionné, par rapport à un standard principal situé en une relation fixe avec la vitesse machine.
  4. Procédé selon la revendication 3, caractérisé en ce qu'un facteur présélectionné est affecté à la commande (12 ; 13) du moteur d'entraînement (06 ; 07), pour modifier une position angulaire en rotation et/ou une vitesse de rotation, corrélée(s) avec la vitesse machine, pour les moteurs d'entraînement (06 ; 07), attribuée(s) par l'axe directeur virtuel (17) et la transmission (G).
  5. Procédé selon la revendication 1, caractérisé en ce qu'un réglage des vitesses périphériques (u03 ; u04) entre elles est modifié, dès que, à la position d'application de pression, une valeur limite d'une puissance (L06 ; L07) consommée, ou d'un couple appliqué, du moteur d'entraînement (06 ; 07) entraînant le cylindre de contre-pression (03) et/ou le cylindre (04), est dépassée.
  6. Procédé selon la revendication 5, caractérisé en ce qu'aucune modification n'est effectuée, tant que la puissance (L06 ; L07), ou le couple appliqué, est inférieur(e) à la valeur limite.
  7. Procédé selon la revendication 1, caractérisé en ce que le réglage des vitesses périphériques (u03 ; u04) entre elles s'effectue au moyen d'une régulation.
  8. Procédé selon la revendication 1, caractérisé en ce que le réglage des vitesses périphériques (u03 ; u04) entre elles s'effectue au moyen d'une commande.
  9. Procédé selon la revendication 7 ou 8, caractérisé en ce que le réglage, ou la commande, agit sur la vitesse de rotation du cylindre de contre-pression (03).
  10. Procédé selon la revendication 1, caractérisé en ce que le procédé est mis en oeuvre manuellement.
  11. Procédé selon la revendication 1, caractérisé en ce que le procédé est mis en oeuvre automatiquement.
  12. Procédé selon la revendication 1, caractérisé en ce qu'un écart (Au) des deux vitesses (u03 ; u04) entre elles est réglé en fonction d'au moins une sorte et/ou une caractérisation de blanchet.
  13. Procédé selon la revendication 5, caractérisé en ce qu'est utilisée comme valeur limite une valeur dans la fourchette comprise entre 70 et 90 % d'un couple nominal du moteur d'entraînement (06 ;07).
  14. Procédé selon la revendication 1, caractérisé en ce qu'une valeur limite pour une différence maximale des vitesses périphériques (u03 ; u04) est respectée.
  15. Procédé selon les revendications 10 et 14, caractérisé en ce que la valeur limite pour la différence des vitesses périphériques (u03 ; u04) en fonctionnement manuel est au maximum de ± 0,2 %.
  16. Procédé selon les revendications 11 et 14, caractérisé en ce que la valeur limite pour la différence des vitesses périphériques (u03 ; u04) en fonctionnement automatique est au maximum de ± 0,02 %.
