An apparatus for winding up a metal strip into a coil. A frame in which a second counter-bending roller is mounted in a rotatable manner. The frame is movable with the aid of a second setting device between a coiler shaft position and a roller bed position. In the roller bed position, the second counter-bending roller alongside a first counter-bending roller acts as the roller bed roller of a roller bed which is arranged above the coiling device.

An overlapping and progressive forming method for a high-performance multi-element NiAl-based alloy tubular part, including: winding continuously flexible substrates of Ni and Al, and alloying coating continuously or selectively along a width direction or a rolling direction to obtain coated flexible substrates; winding continuously the coated flexible substrates on an outer surface of a core roller according to a sequence of Ni above and Al below to form a Ni/Al laminated structure having a plurality of layers with an outermost layer being a Ni layer, and consolidating with ultrasonic with assistance of a pulse current to combine the continuously wound flexible substrates into a laminated tube blank; and placing the laminated tube blank into a mold, applying a pulse current to both ends of the laminated tube blank for hot fluid high-pressure forming, and synthesizing in-situ to prepare the tubular part with assistance of the pulse current.

A machine for winding coils comprising at least one support frame, a belt having a closed-ring configuration installed on the support frame so as to substantially surround it peripherally, and a platform on which the at least one support frame is positioned. The platform is provided with support elements configured to selectively support the at least one support frame in a distanced position with respect to the platform. Actuation members are associated with at least some of said support elements, and are able to be selectively activated to take at least some of said support elements to a first operating position constraining the support frame to the platform, and to a second non-operating position of non-interference with said support frame.

A coiling device includes a coiler (1) having a coiling mandrel (3) for coiling a metal strip (2) which is fed (x) to the coiler (1), and a coiling swing arm (4) having a front and a rear pressure roller (5, 6) and a deflection plate (7). A swing arm drive (8) lines up the coiling swing arm (4) with the coiling mandrel (3) and is driven away from the coiling mandrel (3). An upper duct flap (9) upstream of the coiler (1) in the feed direction (x) for guiding the metal strip (2). A flap drive (10) for positioning the upper duct flap (9) such that, when the coiling swing arm (4) is lined up with the coiling mandrel (3), the upper duct flap is arranged between the coiling mandrel (3) and the front pressure roller (5) of the coiling swing arm (4) or is arranged upstream of the front pressure roller (5) of the coiling swing arm (4). In the first-mentioned case, the metal strip (2) is deflected around the coiling mandrel (3) only by the rear pressure roller (6) and the deflection plate (7) of the coiling swing arm (4) and, in the last-mentioned case, additionally also by the front pressure roller (5).

A strip of metal entering or exiting a mill can be redirected about a roller so as to define an angled segment of the strip of metal, with the angled segment extending away from the roller and arranged at an angle relative to the roller. The angled segment can be connected with a coil that is rotated about a mandrel such that a magnitude of the angle of the angled segment changes as the coil is enlarged or reduced by the rotating of the mandrel. A sensor of a surface inspection system can detect a characteristic of a surface of the strip of metal in the angled segment or in the coil. The sensor can be robotically moved to modify a distance and/or an orientation of the sensor of the surface inspection system relative to the surface.
