Patent ID: 8056212

Claim:
A method of forming a coil for forming the coil by winding one flat type wire material rectangularly edgewise by the use of a winding head thereby stacking the rectangularly edgewise wound flat type wire in rectangular tube shape, characterized in that the method comprises: a feeding step of said flat type wire material for preparing said flat type wire material having a length required for said winding of the coil and then feeding the flat type wire material to said winding head, thereby disposing said flat type wire material in a condition that a head of the flat type wire material is projecting by a predetermined length from said winding head; a start-of-winding step for winding said flat type wire material by the use of said winding head in order that one edge of the coil consisting of the flat type wire including an end portion of start-of-winding thereof may be projecting from outer circumference of the coil; an wire winding step for winding said flat type wire material by the use of said winding head until the predetermined number of windings immediately before the finish-of-winding of the coil; and a finish-of-winding step for winding said flat type wire material by the use of said winding head in order that another edge of the coil consisting of the flat type wire including an end portion of finish-of-winding thereof may be projecting from outer circumference of the coil.
