  • Patent number: 5254220
    Abstract: A process for positioning rigid segments into a paper web being formed through a hybrid band and the resulting article of manufacture from this process. The positioning of the rigid segments with uniform predetermined separation between them and their uniform length provide a wavelength for the hybrid band with the consequent advantage for readily detecting its electromagnetic characteristics. The paper web is divided in continuous adjacent sheets that include each one matrix and surrounding margin areas. The web has one or more sheets across. The matrix includes a set of document areas therein that correspond to the resulting bank notes, or document areas, in the preferred application for this invention. Each resulting document area includes one or more rigid segments that is, or are, symmetrically positioned with respect to a longitudinal and central axis across said document areas.
