Abstract
An apparatus for removing staples from paper, card and like sheet-form material is disclosed. The apparatus includes an anvil which deflects downwardly the leading end portion of a sheet inserted into the apparatus. A staple in the incoming sheet abuts against a tongue which causes the tongue to pivot rearwardly. The tongue is then moved towards the anvil to indent the paper adjacent the staple and orient the staple against the front face of the tongue. Next, the tongue is returned to a vertical position and the staple is pressed upwardly into a relieved portion of a rotary knife. The knife then slices off the top of the staple and removes the sliced off portion. Remaining portions of the staple are stripped from the paper as it is withdrawn from the apparatus.

Apparatus for removing staples from sheet-form material, comprising:
- means defining an opening into which a sheet can be inserted generally in a flat plane with a staple to be removed from the sheet extending generally transverse to the direction of insertion;
- an anvil having a leading edge disposed generally in said plane and extending generally normal to said direction of insertion, said anvil being adapted to deflect out of said plane the leading end portion of a sheet inserted into the opening;
- stop means adapted to locate the staple in said sheet at a cutting station with portions of said staple at a first side of the sheet against said anvil leading edge, said stop means having a staple locating edge extending parallel to said anvil leading edge and positioned for contact by portions of said staple at the second side of said sheet;
- means adapted to engage the portions of the staple located against said stop means and displace the staple towards the sheet so as to cause the staple to protrude from said first side of the sheet;
- and,
- cutter means operable to slice through said protruding portions of the staple along a cut line generally parallel to said plane and in a direction towards said anvil whereby the staple is cut into portions which can separate from the sheet.
