Therefore, when a coil is wound with a square wire manufactured by a usual method, gaps (smaller than gaps with a round conductive wire) between conductive wires still result.
- According to a method of rolling a round conductive wire by a pressure roll, round portions on corners always arise and shapes of the round portions are not uniform. Furthermore, deformation of the wire or dispersion of a wire diameter may be occurred easily.
- When a square wire is made of a thin conductive sheet metal, length of the thin sheet metal as a base material is limited to compete against a round conductive wire. More complex manufacturing machine or cost-up may be concerned. The length of a base material is short so that supplying a thin sheet metal is required at frequent intervals and then continuous automatic operation of a winding machine may be hindered.
- To overcome the above drawback of prior art, one object of this invention is to provide a square wire manufacturing machine which can manufacture a conductive wire, having a square section and being used for a coil, continuously and precisely in low-cost with a relatively simple structure.
