Publication number: 20090024246Abstract: A bending apparatus is provided with a ram start-up device so as to be movable in a lateral direction. A controller moves the ram start-up device to a point in front of positioning points of abutments corresponding to points of selected edges of a workpiece. The bending apparatus includes a foreign object detector that detects the entry of a foreign object into a region of movement of the ram start-up device. A controller prevents the ram start-up device from moving when the entry of the foreign object is detected.Type: ApplicationFiled: March 28, 2005Publication date: January 22, 2009Applicant: AMADA CO., LTD.Inventors: Hidekatsu Ikeda, Takanori Okubo, Kazuhiro Kanno, Hisashi Uto
