A coiling machine for hot rolled stock with a thickness of between 0.5 and more than 5 mm, arranged downstream of a rolling train and a shears assembly (11). The coiling machine comprising a turntable assembly (12) rotating around an axis of rotation (13) orthogonal to the axis of feed of the rolled stock and lying on a plane substantially parallel to the plane of feed (14) of the rolled stock. The turntable assembly (12) supporting two coiling mandrels (15a, 15b) each arranged diametrically opposite each other and with an axis parallel to the turntable axis of rotation (13). The turntable assembly (12) has at least a first operating position wherein the first mandrel (15a) is in a position awaiting the leading end of the rolled stock and ready to begin coiling, substantially cooperating with the plane of feed (14) and at least a second operating position, rotated by 180° with respect to the first operating position, wherein the first mandrel (15a) is in a position where the rolled stock is completely coiled and the coil (30) is ready to be discharged and the second mandrel (15b) is in a position awaiting the leading end of the rolled stock and ready to begin coiling. At least a movable guide blade (20) is arranged upstream of the turntable (12) and includes a first position of exclusion remote from the plane feed (14), a second working position cooperating from above with the plane of feed (14) and a third position wherein it grips the rolled stock during the transition between the two aforesaid positions.
