Abstract:
This coiler device provided with a chute guide has: pinch rollers that lead a metal sheet carried in along a path line to a coil-up line that is curved from the path line; a mandrel that is disposed ahead of the coil-up line and coils up the metal sheet; and a chute guide that guides the upward-facing surface side of the metal sheet at the coil-up line and introduces the metal sheet to the coil-up opening of the mandrel. A configuration is adopted such that the chute guide has: a main body frame; and a liner that is attached to the main body frame, forms at least a portion of the guide surface that guides the metal sheet, has a lower coefficient of friction than the main body frame, and has a lower hardness than the metal sheet.
