Abstract

PURPOSE: To enable a winding of fine coil wire in large number of turns at high speed, by means of providing a roundness in a coil winding lever part of coil winding core through a continuous press work.
CONSTITUTION: A high permeability material like permalloy is successively carried out toward the metal mold as in a band shape, and surface press works are processed at each station for a fixing small hole 3d to the yoke, lever part 3a for the coil wire to be wound, and angle part 3b, to construct a winding core with a roundness formed in the angle part 3b of the coil winding lever part 3a, and a work of fine wire winding is made capable in large number of turns at high speed
