Zusammenfassung:	To make it possible to transport a large size work-piece.SOLUTION: In a clamp process, servo motors 33d, 34d for clamp cause a first feed bar 31 and a second feed bar 32 to approach each other in a contact/separation direction, and synchronously with this, a first servo motor 33f for feed drives the first feed bar 31 in a reverse transport direction and a second servo motor 34f for feed drives the second feed bar 32 in a transport direction. In a separation process, the servo motors 33d, 34d for clamp separate the first feed bar 31 and the second feed bar 32 from each other in the contact/separation direction, and synchronously with this, the first servo motor 33f for feed drives the first feed bar 31 in the transport direction and the second servo motor 34f for feed drives the second feed bar 32 in the reverse transport direction.SELECTED DRAWING: Figure 6 【課題】大きなサイズのワークを搬送出来るようにする。【解決手段】クランプ工程では、クランプ用サーボモータ３３ｄ，３４ｄが第１フィードバー３１及び第２フィードバー３２を互いに接離方向に近づけるとともに、それに同期して、第１フィード用サーボモータ３３ｆが第１フィードバー３１を逆搬送方向に駆動するとともに第２フィード用サーボモータ３４ｆが第２フィードバー３２を搬送方向に駆動する。離間工程では、クランプ用サーボモータ３３ｄ，３４ｄが第１フィードバー３１及び第２フィードバー３２を互いに接離方向に離間させるとともに、それに同期して、第１フィード用サーボモータ３３ｆが第１フィードバー３１を搬送方向に駆動するとともに第２フィード用サーボモータ３４ｆが第２フィードバー３２を逆搬送方向に駆動する。【選択図】図６
