    • PROBLEM TO BE SOLVED: To maintain uniform thickness of an insulating layer in the longitudinal direction of an insulated wire even when productivity of the insulated wire is improved.SOLUTION: A production method of an insulated wire at least includes: an application step to apply insulation coating to an outer circumference of a traveling wire with a coating feed tank; a baking step to bake the insulation coating applied to the outer circumference of the traveling wire with a baking furnace; and a cooling step to cool the traveling wire with a cooling mechanism such that temperature of the traveling wire before application of the insulation coating becomes a predetermined temperature based on the temperature of the traveling wire detected by a temperature detector, and an insulating layer is formed on the traveling wire by repeating the application step, the baking step, and the cooling step.
    • 要解决的问题:即使提高绝缘电线的生产率,也可以使绝缘线的长度方向上的绝缘层的厚度均匀。解决方案:绝缘线的制造方法至少包括:施加绝缘的施加步骤 用涂料给料罐涂覆到行进线的外周; 烘烤步骤,用烘烤炉烘烤施加到行走线的外周的绝缘涂层; 以及冷却步骤,利用冷却机构冷却行进线,使得在施加绝缘涂层之前的行进线的温度基于由温度检测器检测的行进线的温度成为预定温度,形成绝缘层 通过重复施加步骤,烘烤步骤和冷却步骤在行进导线上。
