PROBLEM TO BE SOLVED: To provide a tool and a method for performing the measurement of the parallelism between a mandrel and a unit roll in a winding device of a hot-rolling line, by simple mechanism.;SOLUTION: In a parallelism measuring tool 1, two rings 2 which have an inside diameter which can be fit on the outside diameter of a mandrel 245 when the nose of a material to be rolled (hot-rolled metal strip) is wound round the mandrel 245 are made parallel and are connected with metal bars which is in the direction vertical to the two rings 2. The metal bars 3 are projected from at least one side of the two rings, and positioning tools 4 for positioning at the end of the mandrel 245 are provided on one end of the projected metal bar 3 is provided, both the positions of the two rings 2 when the two rings 2 are fit on the mandrel 245 are between the mandrel 245 of a winding device and unit rolls 241-244 and made so as to be one by one on the drive side and the driven side to the middle in the longitudinal direction of the mandrel 245.;COPYRIGHT: (C)2010,JPO&INPIT
