Abstract

A paper shredding mechanism (10) has two rows of shredding units (400) mounted for rotation in opposite directions, each of which has a flat body (410) with a periphery (412) and left and right sides, at least one piercer (430) projecting from the periphery (412) for piercing and cutting a paper sheet (P) fed through between the two rows, cutting in a first direction transversely of the paper feeding direction, and a shearing edge (422) on each of the left and right sides alongside the periphery (412). The piercer (430) has a cutting edge (432) which extends across the left and right sides of the body (410). The shearing edge (422) bears laterally against the same of an adjacent unit (400) of the other row. The two shearing edges (422) together act as shears for cutting the paper sheet (P) in a second direction parallel to the feeding direction.

Description

technical field [0001] The present invention relates to a shredding mechanism for shredding paper or other sheet material, and to a shredder comprising the shredding mechanism. Background technique [0002] A paper shredder is one of the indispensable devices in an office. Shredders tend to be bulky and power hungry, often requiring access to the power grid for sufficient power to operate. A growing number of relatively more compact shredders are finding their way into the domestic market in reduced size, but in most cases shredders are still limited to mains operation. [0003] Battery operation is desirable for home use because of the freedom of movement and the ability to use in different locations. However, until the issue of power requirements is resolved or at least mitigated, the size cannot be reduced further and battery operation is impractical. In any case, saving electricity consumption is always welcome for environmental reasons. [0004] The present inventio...
