PROBLEM TO BE SOLVED: To provide a bender device having a bender capable of continuously bending a long object such as a pipe in different directions.SOLUTION: A bender comprises a first processing part 12 and a second processing part 22 for a long object (t), and bending processing is applied by relative movement of the second processing part 22 to the first processing part 12. The first processing part 12 is provided on a first shaft 11, and the second processing part 22 is provided on a second shaft 21. Two driving states: one-side driving state of revolving the second processing part 22 in one direction and autorotating it in one direction about the first shaft 11, and the other-side driving state of revolving the first processing part 12 in the other direction and autorotating it in the other direction about the second shaft 21, are selectively executed. The respective autorotations are executed at a rotation angle speed larger than a rotation angle speed of revolution and in the same direction as the revolution direction.SELECTED DRAWING: Figure 2 【課題】パイプなどの長尺体を異なる方向に連続して曲げることが可能なベンダーを備えたベンダー装置の提供を図る。【解決手段】長尺体ｔに対する第１加工部１２と第２加工部２２とを備え、第１加工部１２に対して第２加工部２２を相対的に移動させることによって、曲げ加工を施す。第１加工部１２は第１軸１１に設けられ、第２加工部２２は第２軸２１に設けられる。第１軸１１を中心に、第２加工部２２を一方向に公転させ且つ一方向に自転させる一方側駆動状態と、第２軸２１を中心に、第１加工部１２を他方向に公転させ且つ他方向に自転させる他方側駆動状態との２つの駆動状態が選択的に行われる。公転の方向と同方向にその公転の回転角速度よりも大きな回転角速度によって上記の各自転がなされる。【選択図】図２
