A bending system for separating a page from a cover of a value document, wherein the page is connected to a spine of the cover, the spine separating the cover in first and second cover portions, wherein an angle γ is formed between the first and second cover portions. The bending system includes a bending unit connected to a motor, wherein the motor is configured to operate the bending unit such that the bending unit bends the value document to a first state, where γ is larger than 180°, and then back to a second state, where γ is at least 180° but less than γ in the first state, to separate the page from the cover. Also disclosed is an engraving system for engraving a front side and backside of a page of the value document and a document manufacturing device including the bending system and engraving system.

A data carrier (1) comprises at least a first guiding element (2), at least a first processing element (3), and at least a first security element (4). The first processing element (3) is arranged after the first guiding element (2) with respect to an extension direction (E). The first guiding element (2) is configured to guide impinging electromagnetic radiation towards the first processing element (3). The first processing element (3), in an unprocessed state, is semi-opaque or opaque. In a processed state after being impinged by electromagnetic radiation that is irradiated through the first guiding element (2) onto the first processing element (3), the first processing element (3) in the region of impingement comprises at least a first processed region (5) in the form of a transparent region or translucent region or a hole. The first guiding element (2) and the first processed region (5) at least partially overlap when viewed along the extension direction (E), whereby the first security element (4) is generated.

A security sheet including at least one paper substrate, at least one watermark produced in the paper substrate, the watermark having an exterior outline, at least one aperture of regular edge, produced by ablation of the paper substrate, and at least one security film that is at least partially superposed on the watermark and on the aperture. In the sheet, the at least one aperture lies inside the watermark, such as bounded by its exterior outline.
