Description

The invention relates to a stack cutting machine and a cutting device.

To generate securities such as banknotes, sheets are usually first generated which have a matrix-like arrangement of several columns and several rows of use. These sheets and in particular the panels on them are provided with different security features by means of different processing methods. In order to separate the uses, the sheets are cut. This is preferably done in batches in order to ensure a high process speed.

Securities such as banknotes are often covered with a protective layer, in particular to increase their durability. For example, lacquering or lamination are used here. If a stack of laminated sheets is cut by means of a conventional vertically acting knife, the resulting intermediate stacks and / or utility stacks, in particular stacks of securities or banknotes, can stick together. An intermediate stack is, for example, a stack of intermediate products, each of which still has a plurality of panels and / or edge areas, but which have already been created by dividing a respective sheet. For example, strips with a width of one panel and a plurality of panels arranged one behind the other in the longitudinal direction are such intermediate products and a stack of such intermediate products is an intermediate stack. A stack of securities is preferably a stack of several completed securities, for example bank notes.

Through the EP 0 091 714 A1 , the U.S. 4,283,902 A , the WO 01/49464 A1 and the

WO 2009/130638 A1 Stack cutting machines and methods for cutting stacks of sheets into stacks of copies, in particular stacks of securities, are known.

Through the DE 295 17 466 U1 a device is known by means of which the stacks of sheets can be rotated on a table and aligned relative to a cutting device by means of a positioning device and then trimmed at their edges.

The invention is based on the object of creating a stack cutting machine and a cutting device.
