Abstract: A security document is provided comprising a finished cellulosic substrate having at least one transparentized portion formed therein. The transparentized portion comprises a transparentizing composition that is applied so as to define an area of increased transparency in the substrate. The area of increased transparency includes at least one thin line and resembles a simulated security thread. The transparentizing composition can be applied to form thin lines in a variety of configurations on one or both sides of the substrate.

Abstract: A cellulosic sheet suitable for use as a security document is provided including a multi-functional transparent secure mark formed therein. In accordance with one embodiment of the present invention the secure mark comprises a transparentized portion of the substrate. The cellulosic substrate defines first and second major faces. The transparentized portion comprises a transparentizing composition applied to the cellulosic substrate in a predetermined pattern so as to define a graphical image having a relative transparency selected so as to define an area of increased transparency in the substrate. The transparentizing composition comprises a transparentizing agent and a security agent. In one embodiment of the present invention, the transparentized portion includes a printed portion and printed matter defining the printed portion is covered by the transparentizing composition.

Abstract: An apparatus and method for separating and folding forms cut from a continuous web is provided wherein a swing chute having opposing first and second conveying surfaces positively conveys a form to a delivery table, maintaining control of the form until the trailing edge exits therefrom. The apparatus includes a swing chute for use in a dynamic or zig-zag folding apparatus.
