Abstract (en)

[origin: WO2019186341A1] The present invention concerns a coil winding system of a hot-rolled product comprising: • - a rotating coiler (10) with a vertical axis Y, comprising an outer drum (11) and an inner mandrel (12) coaxial with the outer drum, wherein the outer drum and the inner mandrel delimit an annular interspace (13), which is closed at the bottom by a bottom wall (14) integral with the drum (11) and/or the mandrel (12) and within which the hot-rolled product is deposited and wound in the form of a reel; - means (20) for conveying the hot-rolled product entering the rotating coiler towards the annular interspace. The conveying means are associated with a support frame (21) which is rotationally fixed relative to said coiler. The system comprises means (30) for diverting the hot-rolled product inside the annular interspace from the winding trajectory induced by the rotation of the coiler. The diverting means are located downstream of the conveying means with respect to the entering movement of the hot-rolled product into the coiler and are adapted for setting the radial winding distance R of the hot-rolled product relative to the vertical axis Y of the coiler inside the annular interspace. The diverting means comprise a diverter element (31) which in use comes into contact with the hot-rolled product and the orientation of which inside the annular interspace is adjustable so as to vary the setting of the radial windin distance.
