Abstract

The document shredding machine has a series of notched knife discs which are mounted in rows on a pair of drive shafts which rotate in opposite directions. The discs have a series of grooves (24) cut into their peripheries to produce a finely shredded product. The grooves (24) of axially adjacent discs (12) are displaced along the horizontal stack of cutter blades (12), all the way along the knife (11). The grooves of opposing knife discs (12) intermesh across the roll gap (23).
