Cutting, Bending, Barbing Patents (Class 59/73)
  • Patent number: 6192297
    Abstract: A method for moving metal sheets of a working area by an antropomorphous robot comprises a) taking of preselected fixed input data that identify the geometry in the space of components of a working island; b) taking, comprising from a machine tool, preselected variable input data comprising dimensions and shape of a preselected metal sheet to be handled and a sequence of working preselected metal sheets; c) processing the fixed and variable input data on a processing unit in order to generate automatically output data that identify a preselected trajectory of the metal sheet to be handled and d) transfer the output data to a control unit of the robot in order to drive said robot to move the metal sheet along the preselected trajectory so as to handle said metal sheets selected by type.

  • Patent number: 5060468
    Abstract: In producing the surgical staple, a cutting edge is moved toward each of the leg portions of the wire from which the staple is formed in inclined relation to the axis of the leg portion to shear the leg portion, the leg portion being set on a receiving surface. A smooth sheared surface and a coarse ruptured surface are formed in order on the distal end portion of the leg portion toward the distal end of the leg portion. A shearing member having the cutting edge above serves to bend and shear the leg portions of the surgical staple.
