Abstract

L'invention concerne un procédé de contrôle de la qualité de produits de détail (2) transportés en continu, des produits de détail (2) adjacents étant isolés à une certaine distance les uns des autres et contrôlés extérieurement par un dispositif de contrôle, le procédé étant conçu de façon à déterminer au moins une fois la distance entre deux produits de détail (2) avant d'effectuer le contrôle extérieur, la comparer à une distance minimale prédéterminée et freiner ou accélérer le produit de détail (2) suivant, par référence au sens de déplacement, lorsque l'on constate que la distance est inférieure à la distance minimale.
