Abstract (en)
[origin: DE19802589A1] The bending device bends sheets or strips into trapezoid or other shapes. It has a pressure cylinder (4) with a piston (5) movable perpendicular to a horizontal machine bed (1), with a pressure rest (9) fitted to its piston rod (6), an axially movable punch (11) and pairs of clamping elements (2, 14; 3, 15) consisting of a lower anvil (2, 3) and upper pressure cylinder (14, 15) with extendible piston rod (18) carrying a clamping batten (19).
