CA 2267145

A process and apparatus for controllably registering two continuously moving layers of material is provided. A continuously moving first layer has a plurality of components, and a continuously moving second layer has a plurality of reference marks representing a respective plurality of components. The process and apparatus control the distance between reference marks of the second layer to a selected distance, and then controllably registers each reference mark of the second layer to a respective component of the continuously moving first layer.

La présente invention concerne un procédé et un dispositif de calage contrôlé de deux couches de matériau continuellement en mouvement. Une pluralité de composants est déposée sur une première couche continuellement en mouvement. Une seconde couche continuellement en mouvement est pourvue d'une pluralité de marques de référence correspondant chacune à l'un des composants de la pluralité de composants. Le procédé et le dispositif assurent le réglage, à une distance sélectionnée, de la distance entre les différentes marques de référence de la seconde couche, et le calage contrôlé de chacune des marques de référence de la seconde couche par rapport à un composant correspondant de la première couche continuellement en mouvement.
