Description

[0003] Traditional equipment usually uses independent cutting tools and stripping tools to complete the corresponding processes separately. For example, the wire is first cut into a predetermined length by the cutting device, and then the cut wire segment is sent to the stripping device to remove the outer insulation layer.
