Abstract

Punchings for stator core laminations of a generator stator frame are disposed on a rotary table to form annular arrays of punching, with each layer staggered relative to adjacent layers. A mandrel is disposed at the center of the table and has fingers projecting radially for receiving the slots of the punchings to facilitate location of the punchings on the table and relative to one another. An annular cover is provided and disposed over the uppermost layer of punchings and clamped to the superposed sets of annular layers of punchings. The cover and punchings can then be removed from the table for disposition in the generator stator frame. The fingers on the mandrel are displaced vertically relative to the table as the height of the punchings on the table increases.
