  • Coiled material transporting device, press system and coiled material transporting method
    Patent number: 10792724
    Abstract: A coiled material transporting device is disposed between a coiled material supply device supplying a coiled material, and a press device pressing the coiled material supplied from the coiled material supply device. The coiled material supply device includes a support, a first driver, and a transporter. The support is extendable and retractable along a direction of a die disposed in the press device. The support is configured to support from below a terminal end of the coiled material supplied from the coiled material supply device. The first driver is configured to cause the support to extend and retract. The transporter is provided to the support and is configured to transport the terminal end of the coiled material toward the die disposed in the press device.
