Abstract
A coiler device (1), provided with a chute roller (50), has: pinch rollers (10a, 10b) that lead a metal sheet carried in along a path line (L1) to a coil-up line (L2) that is curved from the path line (L1); a mandrel (20) that coils the metal sheet and is disposed ahead of the coil-up line (L2); and a chute roller (50) that exposes at least the leading end of the metal sheet to the coil-up line (L2) when being wound to the mandrel (20), and suppresses curving of the metal sheet toward a surface of the metal sheet facing the chute roller (50).
