Embodiment Construction

[0054] Figure 1a The embossing machine is shown in side view with an embossing tool in the form of an embossing cylinder 3 and a stretching roller 4 . The embossing machine conveys a strip 1 of continuous film along a path S to an embossing tool in a conveying direction 2 via stretching rollers 4 .

[0055] Strip 1 contains a first component of the security element, for example embossed microstructural information. The first component is supplemented by the second component in order to form the security element. The second component can be, for example, an embossed structure, in particular a microlens structure, which together with the embossed structure forms a moiré amplifier as a security element. For the sake of clarity, the first part is not shown on the strip 1 .

[0056] The continuous film is pressed against the embossing cylinder 3 by means of the back-pressure roller 5 and the draw-off roller 6 in such a way that the structures to be embossed are drawn onto the st...
