Abstract:
1. A rotary lamination apparatus for layering punched out core pieces while rotatively offsetting the core pieces, the apparatus comprising: a die assembly that has an axial hole and an axis, and is rotatable about the axis, the assembly having a die; a mounting table received in the axial hole of the die assembly, wherein the core pieces are layered while being rotatively offset on the mounting table through rotation of the die assembly; a drive portion that rotates the mounting table integrally with the die assembly about the axis of the die assembly, wherein the drive portion includes the die assembly; and a transmission mechanism that is arranged between the die assembly and the mounting table to transmit rotation of the die assembly to the mounting table and to permit the layered core pieces to integrally rotate with the rotation of the mounting table regardless of an axial position of the mounting table in the axial hole during a core piece layering operation.
