Definitions

Some of these are embedded in the security paper in such a way that they are visible on one or both opposite surfaces of the security paper only in certain window areas (hereinafter also called thread windows).
  • Such thread windows are conventionally produced in bronze screens by means of highly embossed webs.
  • the webs are rectangular embossments in the form of a plateau.
  • the width of the plateau serves as a so-called wobble zone for the security thread, the width of which depends on the width of the thread.

Since the thread wobble is synchronized with the displacement period P of the thread window elements 34, the window security thread 22 lies in the panels 42A, 42B at the same point within the thread window 40, even if the Position of the thread window 40 along with the thread 22 varies within the benefit.

Since, in the exemplary embodiment, two sheets lie one behind the other in the circumferential direction of the circular screen, the thread window 40 and the security threads 22 have just half a sinusoidal displacement period in each sheet.
