Abstract

A method of manufacturing a fibrous substrate incorporating at least one elongate impermeable security element 13 with a tessellated edge profile comprises the steps of: bringing the elongate element 13 into contact with a moving support surface having window forming means [10,12 figure 1], e.g. an embossed forming wire of a cylinder mould; and depositing fibres onto a support surface such that the elongate element 13 is incorporated into the fibrous substrate with the element at least partially exposed in a surface of the substrate at windows formed by the window forming means. The elongate element 13 comprises a plurality of wide regions 15,16 separated by narrow regions 14, the wide regions being of a width which obstructs the deposition of fibres thereby forming windows 19 in an opposing surface of the substrate, the narrow regions being of a width to allow fibre deposition. The substrate may be used to form security papers or documents such as banknotes, passports, vouchers certificates, bonds, or the like.
