The present invention relates to improvements in methods of manufacturing security substrates having security features. The method comprises the steps of manufacturing an elongate fibrous tape and fabricating at least one security feature in or on the tape. A base substrate is formed by depositing fibres onto a support surface and the tape is incorporated within the base substrate to form the security substrate during the formation of the base substrate.

L'invention concerne des procédés améliorés de fabrication de substrats de sécurité présentant des caractéristiques de sécurité. Le procédé selon l'invention consiste à fabriquer une bande de fibres allongée et à créer au moins une caractéristique de sécurité dans ou sur la bande. Un substrat de base est formé par dépôt de fibres sur une surface support et la bande est intégrée dans le substrat de base afin de former le substrat de sécurité lors de la formation du substrat de base.
