Abstract:
A leveler/feeder (2) is provided with an upper feed roll (23) and a lower feed roll (24), a servo motor (25), and a feeder control unit (29). The upper feed roll (23) and the lower feed roll (24) are disposed so as to sandwich hoop material (6) and feed the hoop material (6) in a transport direction. The servo motor (25) drives at least one of the upper feed roll (23) and the lower feed roll (24). The feeder control unit (29) has a process drive instruction unit (61) and a working drive instruction unit (62). The process drive instruction unit (61) drives the servo motor (25) so as to feed the hoop material (6) to a press device (3) side in between a press working time and the next press working time.
