Abstract

PURPOSE: To reduce an iron loss, with a welded material, deposited on a tooth part when processing a heat treatment to the layer-built iron plate, stripped off, by means of inserting an expander material into the inside of the tooth part, of layer-built core construction, with the tooth part forced to be radially expanded as well as with a shifting operated in an axial direction.
