ABSTRACT:
A plurality of press devices2are arranged in a plastic working system. The plastic working system includes: a loop correction sensor13for watching a slack of a coil material C intermittently delivered from a preceding first press device2a; and a second slack watching means19for watching a slack of the coil material C generated at the time of sending the coil material C to a succeeding second press device2b. According to the slack generated by intermittent feeding of the coil material C sent from the first press device2a, intermittent feeding is converted to continuous feeding by the feeding means15. At the same time, the continuous feeding speed is subjected to speed increasing/decreasing control. On the other hand, by the second slack watching means19, a slack of the coil material C is watched at the time of feeding the coil material C to the second press device2band the preceding first press device2ais subjected to speed increasing/decreasing control.
