Problems solved by technology

Here, in known embodiments, the detection of said magnetic regions may present difficulties, for example, in the selected banknote transport direction, the inductor of a track-based magnetic sensor encounters a non-magnetic gap between the magnetic regions
[0004] The condition of the machine-readable magnetic area often places constraints on the visually visible design of the security thread, for example because of the limited space available for elements of the visible design, or because the magnetic material reduces the transparency of the inscription area on the reverse side

Embodiment Construction

[0042] The invention will be described below by taking the security element of a banknote as an example. to this end, figure 1 is a schematic diagram of a banknote 10, which has a window security thread 12 exposed in certain window areas on the surface of the banknote 10, and in the area between these window areas, the window security thread 12 embedded in the banknote 10. The window security thread 12 includes a machine readable magnetic region with outstanding verification capability in both banknote transport directions used in machine authenticity checks.

[0043] The transport direction 14 is referred to as transverse transport, since the transport then takes place transversely of the bank notes 10 , in which transport direction 14 the transport takes place along the main axis of the security thread. Correspondingly, the transport direction 16 is referred to as the longitudinal direction, since the transport then takes place in the longitudinal direction of the bank no...

Abstract

The present invention relates to an elongated security element (40) for security papers, value documents and the like, having a longitudinal direction and, perpendicular to the longitudinal direction, a transverse direction, and having, arranged on a support, a magnetic layer (44) that includes machine-readable magnetic regions. According to the present invention, the magnetic layer comprises a plurality of frame-shaped magnet elements (44) that include the machine-readable magnetic regions and that are arranged along the longitudinal direction of the elongated security element (40).

Description

technical field [0001] The invention relates to an elongated security element for security paper, value documents and the like, said security element having a longitudinal direction and a transverse direction perpendicular to said longitudinal direction and having a magnetic layer arranged on a support, The magnetic layer includes a machine-readable magnetic region. The invention further relates to a method for producing such a security element, as well as a data carrier provided with the security element. Background technique [0002] For protection purposes, data carriers (such as value or certification documents) and other valuables (such as designer items) are often provided with a security element to verify the authenticity of the data carrier and at the same time prevent its unauthorized copying. Said security elements are developed eg in the form of security threads which are fully or partially embedded in banknotes. [0003] In order to facilitate automatic verific...
