A device for forming a double-curved object comprises a frame, two elongate clamping heads which are arranged parallel to one another on the frame, a support with an exchangeable shaping die, on either side of which support there are clamping heads, and drive means for moving the clamping heads to and fro transversely with respect to their longitudinal direction, along the shaping die in the direction of a working stroke, during which the sheet is stretched and formed, and a return stroke. At least one of the clamping heads is provided with a double-curved shaping piece.
