Abstract
A method of producing a security element for electronically securing an object, a device for producing the security element and the security element itself form aspects of the present invention. The security element includes a strip element embedded in sheathing. The sheathing has a melting temperature below that of the strip element. The method has associated steps and the device has associated elements for producing the security element from the strip element and sheathing. In each aspect, the ends of the strip element and sheathing are heated and the sheathing ends pulled to seal the strip element in the sheathing.
Claims11
A method for producing a security element for electronically securing an object, having a strip element and sheathing whose melting temperature lies below the melting temperature of the strip, element comprising the steps of:
- providing a strip element of a preselected length defining a longitudinal direction, with a sheating, the strip element further defining end areas;
- initially heating the strip element and sheathing at the end areas;
- and
- stretching the sheathing in the longitudinal direction past the end areas.
A device for producing a security element for electronically securing an object, the security element comprising a strip element defining end areas, and a sheathing in which the strip element is enclosed, the melting temperature of the sheathing lying below that of the strip element, the device comprising:
- two clamping elements defining a first position at which the end areas of the sheathed strip element are clamped, the sheathed strip element defining a longitudinal direction;
- a translating mechanism for moving said two clamping elements in the longitudinal direction of the clamped sheathed strip element;
- a heating device for heating at least the end areas of the sheathed strip element;
- and
- means for pulling the clamping elements with the clamped sheathing at the heated end areas over the ends of the strip element to a second position, said second position lying at least partially outside of the end areas.
A security element for the electronic security of articles, comprising:
- a soft magnetic strip element;
- and
- a sheathing completely enclosing said strip element, wherein:
- the melting temperature of said sheathing lies below that of said strip element;
- and
- said sheathing has tapered ends pulled over the ends of said strip element after heating thereby sealing said strip element in sheathing.
