PROBLEM TO BE SOLVED: To provide a carrying device having a freely shut and freely opened/ closed duplicate work feed preventive mechanism with which device the cycle time of the whole line is shortened, the duplicate feed and mistaken detection are eliminated, and any breakage of a machine is prevented in advance and to provide a carrying method. SOLUTION: In the carrying device having duplicate work feed preventive mechanism in the bending line, a duplicate work feed preventive mechanism K having a gate 1 for partitioning the works which can vertically position and adjust the gap g from an upper surface of a carrying conveyor Cy based on the set value according to the work thickness t is provided on the carrying conveyor Cy of an inlet part of a bending machine body, only one work in the set value is passed. When the work W is outside the set value, the gate 1 for partitioning the works is lowered to realize the closed condition, a remaining work detection sensor 6 detects the works W in the remaining condition on the carrying conveyor Cy, and the carrying conveyor Cy is stopped.
