Abstract (en)
[origin: EP0229645A1] To produce a security paper with an embedded security feature (7) therein in the form of a thread, band or the like, a first layer of paper (3) and a second layer of paper (5) in a second papermaking machine are produced and the security feature (7) is inserted in a defined position between these layers (3, 5). After this, these are pressed together and dried. The individual paper layers (3, 5) can be provided with watermarks (9) or apertures (10, 11) at specific locations with respect to the thread (7), whereby the thread can be specifically exposed at pre-determined positions. <IMAGE>
