ABSTRACT:
Coin wrapper opening apparatus that has a surface with a curved or angled cutting edge fixed to it so that the cutting edge faces away from the surface and projects away from it at a height effective to score or cut the wrapper of a wrapped roll of coins, when brought into cutting relationship with the roll. In several embodiments the surface also includes a guidepath to guide wrapped rolls to the cutting edge. In one embodiment, the cutting edge is shielded by a resilient flap that pushes up and away when a wrapped coin roll passes the cutting edge, and the flap then returns to its original shielding position when the roll is removed. In other embodiments, the cutting edge is shielded by a resilient strip fixed over the cutting edge so that the resilient strip stands away from the cutting edge with no pressure on it, and the resilient strip deforms to allow the cutting edge to pass through an aperture when the apparatus is placed against a wrapped coin roll. Alternatively, a combination of shields can be used: a resilient flap fitting over the cutting edge from the edge of the surface and a resilient strip fitting over the cutting edge from another area of the surface, as well. Also alternatively, a pair of wings with a spring mechanism could be used so that they part when a wrapped coin roll is placed in cutting relationship and cover the cutting edge again when the roll is removed.
