Management method for a coiler apparatus provided with a distributor, in which there is at least an exit of the feeder of semi-worked hot or cold metal products, a reel, and a management device comprising a video recording system focusing on said semi-worked metal product, said distributor and said reel being respectively moved by suitable controlled movement and rotation means, characterized in that said management method comprises: - a step of inserting data in a control and command unit of said management device of the reference operating coiling parameters, said reference operating parameters being at least a desired angle of inclination (α SET i,l), and the equivalent diameter (D SET i,l) of said semi-worked metal product to the i-th rotation of said reel and to the 1-th layer of the coil being formed, said angle of inclination (α SET i,l) being defined between the axis of said exit from the feeder and the instantaneous coiling point of said semi-worked metal product on said reel, - a step of collecting the images from said video recording system during coiling, the collecting of the images being coordinated with the coiling speed; - a step of processing the images and calculating continuously at least the operating parameters (α i,l, D i,l) by means of a processing and calculating unit of said management device, said operating parameters being at least said angle of inclination (α i,l) and said equivalent diameter (D i,l) of said semi-worked metal product; - a step of comparing said operating parameters (α i,l, D i,l) obtained from the collection of images with said reference operating parameters (α SET i,l, D SET i,l) inserted in the control and command unit; - a step of converting the possible differences between said reference operating parameters (α SET i,l, D SET i,l) and said operating parameters obtained (α i,l, D i,l), into coordinated variations (ΔV D FB, ΔV R FB) of the speed of movement (V D) of said distributor and/or of the speed of rotation (V R) of said reel; - a step of coordinated adjustment of the speed of movement (V D) of said distributor and of the speed of rotation (V R) of said reel. - a step of inserting data in a control and command unit of said management device of the reference operating coiling parameters, said reference operating parameters being at least a desired angle of inclination (α SET i,l), and the equivalent diameter (D SET i,l) of said semi-worked metal product to the i-th rotation of said reel and to the 1-th layer of the coil being formed, said angle of inclination (α SET i,l) being defined between the axis of said exit from the feeder and the instantaneous coiling point of said semi-worked metal product on said reel, - a step of collecting the images from said video recording system during coiling, the collecting of the images being coordinated with the coiling speed; - a step of processing the images and calculating continuously at least the operating parameters (α i,l, D i,l) by means of a processing and calculating unit of said management device, said operating parameters being at least said angle of inclination (α i,l) and said equivalent diameter (D i,l) of said semi-worked metal product; - a step of comparing said operating parameters (α i,l, D i,l) obtained from the collection of images with said reference operating parameters (α SET i,l, D SET i,l) inserted in the control and command unit; - a step of converting the possible differences between said reference operating parameters (α SET i,l, D SET i,l) and said operating parameters obtained (α i,l, D i,l), into coordinated variations (ΔV D FB, ΔV R FB) of the speed of movement (V D) of said distributor and/or of the speed of rotation (V R) of said reel; - a step of coordinated adjustment of the speed of movement (V D) of said distributor and of the speed of rotation (V R) of said reel.
