  • the fibrous layer 20 comprises a first pattern in the form of a strip 47 , a second pattern in the form of a strip 48 formed within the first pattern 47 and a third discontinuous pattern 49 formed within the pattern 48 .
  • the pattern 49 is formed from discontinuous zones, these zones being, for example, disks or similar shapes obtained by solid conical jets.
  • the first pattern 47 may comprise second-level security elements, for example fibers that are invisible in ambient light and that have a blue fluorescence under radiation at 365 nm.
  • the second pattern 48 may be formed, for example, from security elements such as HILITETM particles that have a red color in daylight and a red fluorescence under radiation at 365 nm.
  • the third pattern 49 may be formed, for example, from TRACELESSTM markers.
  • the fibrous layer 20 comprises a first continuous pattern 50 that has a shape in the form of a strip and continuous second and third patterns 51 and 52 that also have a shape in the form of a strip and that are superposed over the first pattern 50 .
  • the second and third patterns 51 and 52 are spaced apart from one another.
  • the fibrous layer 20 comprises two patterns 53 and 54 that each have a shape in the form of a continuous strip with parallel rectilinear edges and that are partially superposed in an intersection zone 55 .
  • the first pattern 53 is formed by spraying a dye that has a yellow color in daylight and a yellow fluorescence under radiation at 365 nm.
  • the second pattern 54 is formed by spraying a dye that has a blue color in daylight and a blue fluorescence under radiation at 365 nm.
  • the intersection zone 55 has a color corresponding to the superposition of the yellow and blue colors of the patterns 53 and 54 so that the patterns 53 - 54 form, under UV radiation, three colors, in the style of a yellow/green/blue flag.
  • One of the nozzles may, for example, comprise a valve in order to interrupt the spraying jet.
  • One of the nozzles may be able to be moved on a support, for example in translation or in rotation, especially following an oscillating movement.
  • One of the nozzles may be able to be moved so as to vary the distance between this nozzle and the fibrous layer.
