ABSTRACT:
A system for destroying sheets, particularly banknotes, comprises a first feed system (13) for feeding sheets at a first feed speed to sheet destruction apparatus, a second feed system (2) upstream of the first system (13) for feeding sheets at a second feed speed faster than the first feed speed, and a buffer system comprising a stacking wheel (9) positioned between the first and second feed systems to transfer sheets from the second system to the first system and to compensate for the difference in feed speeds. Typically, the sheet destruction apparatus is a low speed shreeder (14).
