Un procédé d'alimentation en feuilles comporte : une étape d'envoi dans laquelle une feuille est fournie à un côté aval à une vitesse de transport prédéfinie ; et une étape d'accouplement dans laquelle une feuille d'un premier rouleau est poussée contre la surface périphérique externe d'un second rouleau et la feuille du premier rouleau est jointe à une feuille du second rouleau, après quoi la feuille du premier rouleau est coupée au niveau d'une position en amont du joint. Dans l'étape d'accouplement, la vitesse d'envoi de la feuille à partir du premier rouleau est inférieure à la vitesse de transport prédéfinie de l'étape d'envoi et diffère de la vitesse d'alimentation de la feuille à partir d'une unité d'alimentation de l'étape d'accouplement, et avec un mécanisme de stockage, un excès ou une insuffisance de feuilles se produisant en raison de la différence de vitesse entre la vitesse d'envoi et la vitesse d'alimentation est reçu(e) et stocké(e) ou rejeté(e).
