PURPOSE:To bend simultaneously two pieces of molding with one bending machine and to remarkably improve the working efficiency of bending. CONSTITUTION:A machine stand 10, an upper die stand 20 and a lower die stand 21 provided on two stages of upper and lower on the machine stand, an upper bending die and a lower bending die provided on the upper die 20 and a lower die 21, machine stand side tension bending devices 40, 41 which are respectively arranged to the positions corresponding to an upper bending die 30 and a lower bending die 31 of mutually differential side parts of the machine stand and are provided freely reciprocating to each bending die direction while clamping one side of ends of the bent stock with the prescribed tensile strength, and die stand side tension bending devices 50, 51 which are respectively arranged to the positions corresponding to the upper bending die and the lower bending die of one side of side parts being mutually differential of the upper die stand and the lower die stand and provided freely reciprocating to each bending die direction while clamping the other side of ends of the bent stock being clamped with the machine stand side tension bending device are composed. |
