Title:
METHOD FOR TREATING WORKPIECES SHAPED LIKE CIRCULAR BLANKS, COINS OR THE LIKE
Document Type and Number:
WIPO Patent Application WO2000040396
Kind Code:
A3
Abstract:
The invention relates to a treatment line and to methods and devices for destroying workpieces that are shaped like circular blanks. Such blanks are, for example, circulated as coins and they have to be obliterated reliably, verifiably and at low costs partially in large amounts once they are removed from circulation. To this end, the invention provides a device for treating workpieces that are shaped like circular blanks and devices for derolling and unwrapping said blanks. In this combination, these devices facilitate an obliteration of workpieces that are shaped like circular blanks without almost any human intervention. The invention also relates to preferred configurations of these devices.
