ABSTRACT:
Shredding devices and methods are disclosed for automatically feeding multiple sheets of paper to be simultaneously shredded. The shredding devices include an auto feed portion for receiving and advancing the paper to be shredded. Certain examples include a paper feed tray and an auto feed assembly having a rotatable elongated shaft and a plurality of disks disposed thereon. As the elongated shaft rotates, the plurality of disks engages a stack of paper present in the feed tray and advances multiple sheets of the stack of paper to shredding blades. Certain feed trays are further configured to fold into a top portion of the housing during non-use and can advantageously protect the auto feed assembly. Certain shredding devices further include at least one feed slot for receiving material manually fed into the shredding device by the user.
