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.

An unwinding device (1) for unwinding a strip (5) which had been wound to form a coil (3), in order for the unwound strip (5) to be hot-rolled. The unwinding device (1) has at least two bottom rollers (7) for supporting the coil (3) on the lower side of the coil, a detaching mechanism (9) for detaching a strip end (11) from the coil (3) on an unwinding side of the coil, and a downholder roller (13), (14) which is disposed at the coil (3) such that the downholder roller (13), (14) stabilizes the position of the coil (3) when the strip end (11) is being detached.

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.

An apparatus (100) for making a coil (B) comprises a feed unit (2) configured to feed at least one strip-shaped article (N) formed by a plurality of strips and a winding unit (1) that includes at least one winding head (10) configured to wind said strip-shaped article (N) to make said coil (B). The feed unit (2) comprises a movable portion (20), wherein respective feed paths (8) comprising a respective storage segment (81) are defined for each of the strips and is configured so as to vary, by moving said movable portion (20), the length of the storage segments (81), keeping said storage segments (81) substantially parallel to each other.

Systems and methods of pre-ageing of a metal strip during metal processing include passing the metal strip adjacent a magnetic rotor of a reheater. The systems and methods also include heating the metal strip through the magnetic rotor by rotating the magnetic rotor. Rotating the magnetic rotor induces a magnetic field into the metal strip such that the metal strip is heated.
