During FPC production, a protective film, known as the FPC cover film, is typically applied to the printed circuits to protect them.

[0038] The covering film is generally attached to the flexible material before being covered on the FPC. Therefore, the prior art has designed a covering device including a film-lifting mechanism and a material pulling mechanism. The film-lifting mechanism is used to separate the covering film from the flexible material. After the covering film and the flexible material are separated, the material pulling mechanism is used to pull and recycle the flexible material.
