An apparatus (1) for winding-up a metal strip (2) into a coil (3), includes a clamping pair (22) formed of a deflection roller (23) and a pressure roller (24) and located in front of the coil (3) in a material flow direction (10) so that the strip (2) is retained under tensional stress with respect to the coil (3) and is so bendable that the strip (2), which is provided with a corresponding pre-bend, is firmly wound into a coil (3). The apparatus further includes a first bending roller (35) pressable against the deflection roller (23), and arranged in front of the clamping pair (22) in the material flow direction (10), and a further roller (36) adjustable relative to the deflection roller (23) and arranged behind the clamping pair (22) in the material flow direction (10), with the pressure roller (24) and both bending rollers (35, 36) being so displaceable relative to the deflection roller (23) that an end region (45) of the strip (2) is additionally curved to form the pre-bend dependent on an end diameter (48) of the coil (3).

A metal wire feeder device including a body presenting a wire braking member, one or more pulleys driven by respective motors about which the wire is wound, the wire before reaching a processing machine passing through a compensator member and a tension sensor, an electronic control unit able to continuously measure the tension value and make it uniform at a predetermined value by acting on a first regulator loop operating on the motors and a second regulator loop operating on the compensator member. The electronic control unit operates automatically in making the tension uniform at the predetermined value, on the basis of the fed wire quantity or of the wire feed velocity.

An aluminum plate coiling device capable of coiling an extruded and rolled aluminum plate without generating distortion or deformation of the aluminum plate is disclosed. The aluminum plate coiling device has a simple structure, thereby being capable of achieving a reduction in installation space and a reduction in installation cost.

A device for measuring a metal plate, a measuring method, and a method for manufacturing a metal plate that enable continuous measurement of a surface shape of a metal plate in a wider range are provided. The device for measuring a metal plate includes a transfer mechanism that transfers the metal plate in a longitudinal direction D2, a sensor that measures a surface shape of a first surface of the metal plate, a stage with which a second surface of the metal plate positioned opposite to the first surface comes into contact during measurement by the sensor, and a control unit that repeatedly executes a first step, a second step, and a third step.
