Disclosed is a registration system and a method useful for controlling and correcting the phase and position of simultaneously advancing webs having pre- printed objects spaced at a pitch length characterized by small but significant pitch variation to a target web. Also disclosed are consumer products, such as disposable absorbent articles including the preprinted objects which were previously included in the webs phased before combining with a target web by utilizing the instant registration system. The pre- printed objects may include pre-printed, pre-bonded, pre-applied, pre-cut, or pre-glued objects or elements of disposable absorbent articles or registration marks produced on a separate independent process not control-linked to the instant registration method. The registration marks may be visible or normally invisible to the human eye.

L'invention concerne un système d'enregistrement et un procédé destinés à commander et à corriger la phase et la position de bandes en mouvement simultané, comportant des objets pré-imprimés espacés selon différents intervalles caractérisés par de petites mais déterminantes variations d'espacement, vers une bande cible. Elle concerne aussi des produits de consommation, tels que des articles absorbants jetables comprenant les objets pré-imprimés, contenus dans les bandes synchronisées avant leur combinaison avec une bande cible obtenue par utilisation du système d'enregistrement instantané. Les objets pré-imprimés peuvent être soit des objets, ayant subi une opération préalable d'impression, de liaison, d'application, de découpe ou d'encollage, ou des éléments d'articles jetables ou des marques d'enregistrement produits sur une ligne de traitement indépendante, non pilotée par le procédé d'enregistrement instantané. Les marques d'enregistrement peuvent être visibles ou invisibles à l'oeil humain.
