Title: Coiling machine for hot rolled stock such as strip or sheet

Abstract: A coiling machine for hot rolled stock with a thickness of between 0.5 andmore than 5 mm, arranged downstream of a rolling train and a shearsassembly (11). The coiling machine comprising a turntable assembly (12)rotating around an axis of rotation (13) orthogonal to the axis of feed ofthe rolled stock and lying on a plane substantially parallel to the planeof feed (14) of the rolled stock. The turntable assembly (12) supportingtwo coiling mandrels (15a, 15b) each arranged diametrically opposite eachother and with an axis parallel to the turntable axis of rotation (13).The turntable assembly (12) has at least a first operating positionwherein the first mandrel (15a) is in a position awaiting the leading endof the rolled stock and ready to begin coiling, substantially cooperatingwith the plane of feed (14) and at least a second operating position,rotated by 180.degree. with respect to the first operating position,wherein the first mandrel (15a) is in a position where the rolled stock iscompletely coiled and the coil (30) is ready to be discharged and thesecond mandrel (15b) is in a position awaiting the leading end of therolled stock and ready to begin coiling. At least a movable guide blade(20) is arranged upstream of the turntable (12) and includes a firstposition of exclusion remote from the plane feed (14), a second workingposition cooperating from above with the plane of feed (14) and a thirdposition wherein it grips the rolled stock during the transition betweenthe two aforesaid positions.
