摘要： This coiler device (1) provided with a chute guide (40a) has: pinch rollers (10a, 10b) that lead a metal sheet (2) 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 is disposed ahead of the coil-up line (L2) and coils up the metal sheet (2); and a chute guide (40a) that guides the upward-facing surface side of the metal sheet (2) at the coil-up line (L2) and introduces the metal sheet (2) to the coil-up opening (23) of the mandrel (20). A configuration is adopted such that the chute guide (40a) has: a main body frame (70) ; and a liner (72) that is attached to the main body frame (70), forms at least a portion of the guide surface (42) that guides the metal sheet (2), has a lower coefficient of friction than the main body frame (70), and has a lower hardness than the metal sheet (2).

摘要： This coiler device (1) provided with wrapper aprons (22) has: a mandrel (20) that coils up a metal sheet ( 2); a plurality of wrapper rollers (21) that coil the metal sheet (2) to the mandrel (20); and a plurality of wrapper aprons (22) that guide the leading end of the metal sheet (2) between adjacent wrapper rollers (21). A configuration is adopted having a fluid supply device (70) that supplies a fluid to the guide surfaces (22a) of the wrapper apron (22A) disposed at the most upstream side with respect to the coiling of the metal sheet (2).

摘要： This gate device (30) is provided with a guide unit (70) having a guide section (70) that is disposed at the downstream side of pinch rollers (10a, 10b) at a path line (L1) along which a metal sheet (2) is conveyed, opens/closes a coil-up line (L2) that is curved from the path line (L1), and guides the upwards-facing surface side of the metal sheet (2) led in to the coil-up line (L2) . A configuration is adopted such that the guide unit (70) has a main body frame (71) and a liner (72) that is attached to the main body frame (71), forms at least a portion of the second guide surface (32) that guides the metal sheet (2), has a lower coefficient of friction than the main body frame (71), and has a lower hardness than that of the metal sheet (2).
