PROBLEM TO BE SOLVED: To provide a method and device for the rotary lamination of a laminated core which makes smooth rotation of a die holder during the rotary lamination and reduces friction resistance of a rotary slider, thereby achieving load reduction.SOLUTION: The device for the rotary lamination of a laminated core includes: a die holder 13 for fixedly supporting a die 11 and a squeeze ring 12 provided below the die 11; die holding hardware 16 that is fixedly disposed and rotatably holds the die holder 13 via bearings 14, 15; and a rotation drive unit 17 for the die holder 13. Compressed air jetting holes 22, 23, 23a for applying floating force to the die holder 13 are provided in the die holding hardware 16 to reduce rotation resistance of the die holder 13. |
