Paper Shredder Product
A cross-cut office shredder: an induction motor drives two intermeshing hardened cutter shafts through a reduction gearbox, slicing fed sheets into confetti that falls into a waste bin, with sensors that auto-start, reverse on jams, and stop when the bin is full or the head is lifted.
