  • Patent number: 4619411
    Abstract: An apparatus for and a method of extraction reinforcements from reinforced cable is described. The apparatus comprises gears between which the reinforcement is engaged and pulled from the remaining cable, the gears also serving to impart a deformation to the reinforcement. A subsequent engagement between gears imparts further deformation sufficient to cause fracture of the reinforcement.A tool attachment for the apparatus comprises an elongate member having a passage for the reinforcement and a tapered end portion which causes the outer strands of a centrally reinforced cable to spread as they are pulled over the end portion. The tool is preferably used in combination with a cutter which cuts the strands after they have been pulled over the end portion. A blade may also be attached to the tool to co-operate with the cutter.
