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).

A wire handling device for a manufacturing device includes an elongate first wire guiding device having a first guiding section for a wire to be guided along the first guide section, and an elongate second wire guiding device having a second guiding section for a wire to be guided along the second guide section. The wire handling device includes a support device, and the first wire guiding device and the second wire guiding device are placed on the support device. The support device is rotatably mounted about the rotational axis, and the first wire guiding device and the second wire guiding device are mounted so that they can be moved with respect to each other.

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.

A station (100, 110) for inspecting rolled strips wound in coils, comprises: a first pair of mutually opposed pinch rolls (3, 4), adapted to receive and feed a rolled strip (1) from a coil (10); a carriage (7) sliding between a first start position, near said first pair of pinch rolls (3, 4), and a second end position, said sliding carriage (1) comprising a gripping member to grasp said rolled strip (1) coming from said first pair of pinch rolls (3, 4), said carriage allowing the strip to be unwound without contact with a surface (S1) to be inspected.

A coiled material passing device is usable to pass a coiled material played out by an uncoiler to a leveler feeder configured to correct any winding curl of the coiled material. The coiled material passing device includes a clamper configured to clamp a starting end of the coiled material played out from the uncoiler, a moving body configured to support the damper, the moving body being movable between the uncoiler and the leveler feeder, and a first driver configured to move the moving body.

The invention relates to a device for unwinding a coil of a metal strip including a bogie translatable back and forth along a guiding system; a blocking system which is arranged on said bogie and which contains a first and a second shaped element, wherein the first shaped element is a roller, preferably an idle roller; an actuating system for modifying the distance between the two shaped elements, for defining an intercepting position and a gripping position of the strip; and an element for detaching the strip from the coil provided on the first shaped element. A relative method of unwinding and inspecting a metal strip is also described, in particular used to check the state of wear of rolling cylinders used for producing the inspected strip.

An intelligent coil leveling validating system includes a platform, a coil inputting device, a leveling device, a curvature measuring device and a processor. The coil inputting device is disposed on the platform. The coil inputting device includes an inputting end and the coil. The coil is movably connected to the inputting end. The leveling device is disposed on the platform and configured to move the coil. The leveling device has a practical downward moving distance. The coil is pressed and rolled by the leveling device, and then has a second curvature. The curvature measuring device detects the coil and obtains the second curvature. The processor generates a simulated downward moving distance of the leveling device according to a response surface method. The processor receives the second curvature and performs feedback control to adjust the practical downward moving distance close to the simulated downward moving distance.
