Abstract
This gate device is provided with a guide unit having a guide section that is disposed at the downstream side of pinch rollers at a path line along which a metal sheet is conveyed, opens/closes a coil-up line that is curved from the path line, and guides the upwards-facing surface side of the metal sheet led in to the coil-up line. A configuration is adopted such that the guide unit has a main body frame and a liner that is attached to the main body frame, forms at least a portion of the second guide surface that guides the metal sheet, has a lower coefficient of friction than the main body frame, and has a lower hardness than that of the metal sheet.
