Abstract (en)
[origin: US4842473A] The manipulator for sheet-metal pieces is used in conjunction with a sheet-metal working machine and has two rotatable holding members (20) displaceable in three dimensions. The holding members (20) each have both clamping tongs (22), which act on the surface of the sheet-metal piece (24) to be worked, and a clamping strip (23) exerting pressure parallel to the sheet surface. It thereby becomes possible for the sheet-metal piece to be worked, in a first working phase when it is still plane, to be grasped along two parallel edges by means of tongs and, after the first working, to be held only by means of the clamping strips.
