ABSTRACT OF THE DISCLOSURE A tool to dewire a bale of dry pulp, waste paper or the like. The tool grabs the wire, cuts it and retains the cut wire. The same sequence of operation is repeated for other wires. The tool then coils the cut wires and discharges the coils as waste. The tool comprises a support casing in which is rotatably mounted a vertical cylindrical tube. This tube includes at its bottom end a pair of opposite slots having a lower portion spiralling for about a quarter of a turn, and an upper portion which extends longitudinally of the tube. A grabber arm, operated by a hydraulic cylinders, is mounted within the tube for up-and-down movement. Wire bending elements and a cutter blade are also mounted within the tube. In operation the tool tube is positioned over a selected wire and applied on the bale. The tube is rotated about one-quarter of a turn to pick up the wire in its spiral slots and raise the wire off the bale. The grabber arm then hooks the wire and pulls the same up. The wire is bent, is cut and its bent end is retained in the tube. Several wires can be cut and retained in the same manner. The tube is then rotated several turns, to be used as a mandrel in association with a coil-forming shoe, so as to wind the wires into compact coil. Then the shoe extracts the coil from the tube for discharge into a bin.
