Abstract:
There is described a method for controlling the position of numbering wheels (7) of a numbering device (1), which numbering device (1) is of the type comprising a plurality of independently-driven numbering wheels (7) disposed adjacent to one another for rotation about a common rotation axis, the method comprising actuating the numbering wheels (7) between successive numbering iterations, whereby each numbering wheel (7) which has to be rotated to a new target position is driven into rotation until it reaches its new target position. The method further comprises, at least during actuation of the numbering wheels (7), compensating for external factors acting on the numbering wheels (7), such as friction induced by adjacent rotating numbering wheels, by electronically regulating the position of each numbering wheel (7) which is not rotated or which has reached its new target position. Also described is a device for carrying out this method.

There is described a method for checking the authenticity of security documents, in particular banknotes, wherein authentic security documents comprise security features printed, applied or otherwise provided on the security documents, which security features comprise characteristic visual features intrinsic to the processes used for producing the security documents. The method comprises the steps of (i) acquiring a sample image of at least one region of interest of the surface of a candidate document to be authenticated, which region of interest encompasses at least part of the security features, (ii) digitally processing the sample image by performing a decomposition of the sample image into at least one scale sub-space containing high resolution details of the sample image and extracting classifying features from the scale sub-space, and (iii) deriving an authenticity rating of the candidate document based on the extracted classifying features.
Abstract:
There is described a method for applying foil material onto successive sheets, especially sheets of securities. In a first step, individual sheets are transported in succession along a sheet transport path. In a second step, at least one continuous band of foil material is applied onto the individual sheets along a direction substantially parallel to a direction of displacement of the individual sheets, thereby forming a continuous flow of sheets linked to one another by the said at least one continuous band of foil material. In a third step, the said at least one continuous band of foil material is cut such that the continuous flow of sheets is again separated into individual sheets with portions of foil material remaining on the sheet. The cutting is performed at positions located on the sheets such that said portions of foil material remaining on the sheets do not extend beyond leading and trailing edges of the sheets. There is also described an installation for carrying out the above method.
