全に除去されない場合が生ずるといった欠点がめった。Conventionally, this was done manually using a Hikari 7 Aipah peeler for each fiber (for example, Japanese Patent Application No. 60-7953).
Conventional example shown in Fig. 14 shown in No. 5 "Optical fiber coating remover"). In this case, conventional methods required manual work, which required a large work space and required the operator to apply force differently when removing the rainbow nuclide, which could result in the optical fiber breaking or the coating not being completely removed. There were a few drawbacks:

No. 71 "Fully automatic fusion splicing equipment for optical fibers") has the disadvantage that if two stripping devices are provided, the entire device becomes larger, and one stripping device can sequentially remove the coating from 1° pair of core wires. In this case, the disadvantage is that the operating time becomes longer.
