  • Patent number: 6115904
    Abstract: An apparatus and method for severing and removing wires surrounding a bale of pulp are disclosed, as well as a unique severing and coiling head. A bale of pulp is loaded onto a turn conveyor and the turn conveyor transports the bale from where it was loaded to the operating position, where a containment disk is lowered onto the top of the bale to restrain the wires wrapped around the bale during severing. A control arm moves a severing head until the head is in contact with the lateral surface of the bale, and keeps it there during the severing and removal process. The turn conveyor rotates the bale through 360 degrees about its vertical axis, thus drawing the severing head across each of the four lateral faces of the bale. The severing blade's teeth engage the wires, pull them free from the bale, and coil them around a spool that is coaxial with the severing blade and attached thereto.

    Abstract: An apparatus for severing and removing wires surrounding a bale of pulp are disclosed, as well as a unique severing and coiling head. A bale of pulp is loaded onto a turn conveyor which transports the bale from where it was loaded to the operating position, where a containment disk is lowered onto the top of the bale to restrain the wires wrapped around the bale during severing. A control arm moves a severing head until the head is in contact with the lateral surface of the bale, and keeps it there during the severing and removal process. The turn conveyor rotates the bale through 360 degrees about its vertical axis, thus drawing the severing head across each of the four lateral faces of the bale. In the first 90 degree increment of the bale's rotation, the teeth of a rotating severing blade engage the wires on the first lateral face of the bale and sever them. In the next 90 degree increment of the bale's rotation, the severing blade engages the wires on the second lateral face of the bale and severs them.

  • Patent number: 6044738
    Abstract: A method for removing wires from a bale of waste cardboard and paper material that is compacted in vertical layers with wires running at right angles to the layers and in vertical planes. A cutting blade is moved downwardly through the wires and bale of waste material to separate a forward portion of the bale of waste material from the remainder of the bale of waste material and from the cut wires. The cut wires are gathered ahead of and beneath the bale of waste material into a bundle with opposed pairs of hook blades moved toward one another to interdigitate in overlapping relation to grasp the bundle of wires in a wire-receiving recess. A rotating fork is inserted into the wire receiving recess to coil the cut wires and pull them free from the bale of waste material as the bale of waste material is moved forward. The recess is cleared by withdrawing the fork from the coil and pushing the coiled wire with a pushing finger clear of the recess.
