Abstract
A rotary lamination apparatus has a die assembly rotatable about an axis and a mounting table received in an axial hole extending through the die assembly. Through rotation of the die assembly, punched core pieces are mounted on the mounting table while being rotatively offset. A drive mechanism is employed to rotate the mounting table integrally with the die assembly about the axis of the die assembly.
