Title: PRESSING DEVICE AND METHOD FOR CONTROLLING PRESSING DEVICE
Abstract:
A pressing device (4) is capable of selectively pressing either a coil material (100) or a sheet material (101), and the pressing device (4) is provided with a pair of bars (51) and a lift drive mechanism (53). Each of the pair of bars (51) has a center section (51c), a first end section (51a), and a second end section (51b). The center section (51c) can hold the sheet material (101). The first end section (51a) is in the upstream of the center section (51c) in the transfer direction (X) of the materials, and is connected to the center section (51c) such that the first end section can be separated from the center section. The second end section (51b) is in the downstream of the center section (51c) in the transfer direction (X), and is connected to the center section (51c) such that the second end section can be separated from the center section. At the time of pressing the coil material (100), the lift drive mechanism (53) moves the first end section (51a) to an upper retraction position (P11).
