Flat wire distortion removal apparatus

Abstract

A flat wire distortion removal apparatus capable of contributing to preventing flat wires from being defectively processed is provided. A flat wire distortion removal apparatus according to an aspect of the present disclosure is a flat wire distortion removal apparatus, including a roller leveler configured to obtain parallelism between two side surfaces of the flat wire in a width direction by making the flat wire pass between a pair of rollers. The roller leveler includes a holding part configured to prevent the flat wire from rotating around an axis extending in a length direction of the flat wire.

What is claimed is: 
     
         1 . A flat wire distortion removal apparatus comprising a roller leveler configured to obtain parallelism between two side surfaces of the flat wire in a width direction by making the flat wire pass between a pair of rollers, wherein
 the roller leveler comprises a holding part configured to prevent the flat wire from rotating around an axis extending in a length direction of the flat wire.   
     
     
         2 . The flat wire distortion removal apparatus according to  claim 1 , wherein the holding part comprises:
 a first holding plate disposed to be opposed to a first surface of the flat wire, the first surface being one of two surfaces of the flat wire in a thickness direction, and   a second holding plate disposed to be opposed to a second surface of the flat wire, the second surface being the other one of the two surfaces of the flat wire in the thickness direction.   
     
     
         3 . The flat wire distortion removal apparatus according to  claim 1 , wherein the holding part comprises:
 a holding plate disposed to be opposed to a first surface of the flat wire, the first surface being one of two surfaces of the flat wire in a thickness direction; and   a holding roller configured to come into contact with a second surface of the flat wire and rotatable around an axis extending in the width direction of the flat wire, the second surface of the flat wire being the other one of the two surfaces of the flat wire in the thickness direction.   
     
     
         4 . The flat wire distortion removal apparatus according to  claim 1 , wherein the holding part comprises a groove formed on a circumferential surface of the pair of rollers, the groove being configured so that an end of the flat wire in the width direction is inserted thereinto in a state in which the flat wire is disposed between the pair of rollers. 
     
     
         5 . The flat wire distortion removal apparatus according to  claim 1 , further comprising another roller leveler different from the roller leveler, the other roller leveler being configured to obtain parallelism between two side surfaces of the flat wire in a thickness direction before the flat wire is made to pass through the roller leveler.
