Abstract (en)
[origin: EP1112788A1] The bending device has a lower pressure cylinder (8) having a piston (9) displaced perpendicular to the horizontal machine bed, with an attached piston rod (12) supporting a pressure surface (13) cooperating with an axially displaced pressure die (15) on the upper side of the metal sheet or sheet metal band (27), held between 2 vertically and horizontally adjustable pressure clamps (2,18; 3,19) on opposite sides of the pressure cylinder and the pressure die.
