Abstract
The present invention is generally related to an apparatus having cutter elements for destroying articles such as paper sheets and a mechanism for advancing at least a top sheet from a stack of paper in a tray into the cutter elements for shredding. In one embodiment, the apparatus uses a rotatable feed roller to feed paper atop the stack to the cutter elements. The feed roller moves in an alternating manner between a lowered and raised position to engage and disengage the stack when advancing the paper therethrough. Alternatively, a rotatable cam may be used. In an embodiment, the apparatus uses a rotatable drum or rotatable belt with an internal vacuum to lift paper from the stack and feed into the shredder mechanism.
