【発明の詳細な説明】 ［産業上の利用分野］ 本発明はエナメル線の製造方法に関するものである。[Detailed description of the invention] [Industrial application field] The present invention relates to a method for manufacturing enameled wire.

度を調整しながら行っていた。[Prior Art] A conventional method for forming an insulating film on an enameled wire is as shown in FIG. After applying the insulating varnish, the varnish is applied to the entire surface of the running line 1 using a drawing felt 4. The applied varnish will burn.
It is baked onto the surface of the running wire 1 in a furnace 5 to form an insulating film. By repeating this painting and baking process multiple times, a finished outer diameter within a predetermined range was obtained. However, since the amount of varnish applied tends to change due to fluctuations in varnish viscosity, temperature, linear speed, etc., the finished outer diameter has been adjusted while adjusting the rotational speed of the varnish application roll 3.

ダイス６に交換する必要があった。FIG. 4 shows another conventional example. In this example, the drawing felt shown in FIG. 3 above is replaced with a painting die 6. Since the amount of varnish applied is almost determined by the outer diameter of the coating die 6, the finished outer diameter is relatively stable. However, fine adjustment of the outer diameter of the finishing requires replacing the coating die 6 with a different hole diameter.

、人手によれば作業能率が低下する。[Problems to be Solved by the Invention] The felt drawing method shown in FIG.
There is a drawback that fluctuations in the finished outer diameter are likely to occur. To prevent this, equipment such as indoor temperature control and varnishing is required, which increases the cost of equipment extremely. It is also possible to adjust the finished outer diameter by frequently adjusting the rotational speed of the varnish application roll, but automatic adjustment similarly increases equipment costs, and manual adjustment lowers work efficiency.
第４図に示したダイス絞り法では仕上外径の調整を行う
には塗装ダイスの交換を行うしかなく、ダイス交換によ
り作業能率が低下し、又、非常に数多くの外径の宜なる
塗装ダイスを常備する必要がある。In the die drawing method shown in Fig. 4, the only way to adjust the finished outer diameter is to replace the coating die, which reduces work efficiency and requires a large number of coating dies with various outer diameters. It is necessary to keep it on hand.
