A system and the relevant thermo-electromechanical process with two superimposed devices (A) able to coil and uncoil a pre-strip (a) by reversing their positions, provided with outer ( 4 ) and inner ( 7 ) burners to respectively equalize and optimize the temperature along the whole pre-strip by means of special algorithms of the control software, suited to also control the speed, acceleration and deceleration, both in the coiling and uncoiling step, of the chuck ( 6 ) up to the advanced stop during coiling to let a segment of tail (c) of the pre-strip out of the device (A). A particular structure of the chuck ( 6 )is also described. |
