Abstract: A security substrate for a document of value comprises a laminate including a generally transparent core layer and generally transparent outer layers on opposite sides of the core layer. At least one interference filter is embedded within the laminate. The interference filter includes a highly reflective opaque layer on a surface of the core layer and an optically variable thin film multilayer overlying at least a portion of the opaque layer. The interference filter is covered by one of the outer layers.

Abstract: Applied to a substrate such as paper banknotes is a thread which includes a PET carrier layer with release layers on both surfaces of the carrier layer, and a metallic layer outward of one release layer. An adhesive layer lies outward of the metallic layer. When a substrate is brought into contact with the adhesive layer, the result is to bond the metallic layer to the substrate. Following this, the PET carrier layer is peeled away, leaving the metallic layer bonded to the substrate. An apparatus for accomplishing these steps includes means for bringing the substrate into contact with the adhesive layer, and means for peeling the PET carrier layer away so that it separates from the metallic layer at the adjacent release layer.

Abstract: An apparatus for applying stripes on a carrier to a moving web includes a first drive to advance the carrier continuously from an unwind reel to a take-up reel at a generally constant speed. A nip is intermediate the unwind reel and the take-up reel through which the carrier and the web pass. The nip applies the stripes to the web. A reciprocating shuttle is moveable back and forth along a generally linear path. The shuttle includes a first set of spaced rollers thereon adjacent one end thereof and a second set of spaced rollers thereon adjacent an opposite end thereof. A first stationary set of spaced rollers is associated with the first set of rollers. The first stationary set of spaced rollers is positioned adjacent one end of the path and intermediate the unwind reel and the nip. A second stationary set of spaced rollers is associated with the second set of rollers. The second stationary set of spaced rollers is positioned adjacent an opposite end of the path and intermediate the nip and the take-up reel.
