PURPOSE:To enable thorough removal of a covering from an optical fiber core even at a relatively wide space between blade edges by holding elastically the optical fiber core and exerting removing force to the covering by the inclined blade surfaces thereby preventing buckling deformation of the core and the positional deviation of the optical fiber. CONSTITUTION:When the end of an optical fiber core A to be removed of a covering 2 is positioned to the side of elastic bodies 71, 72 and when an upper member 51 and a lower member 52 are pressed to each other, the side face of the covering is supported by the bodies 71, 72 are therefore the covering is hardly buckled and deformed. While the force for removing the covering is exerted to the core A by pulling the core, compressive stress is applied to the slopes 91a, 92a of blades 81, 82 perpendicularly to said faces and the axial component (fx) thereof generates shearing stress to the surface of the fiber 1, thereby stripping the covering 2. The compressive stress component (fy) acting perpendicularly to the surface of the fiber 1 increases sharply when the blade edges approach to the fiber 1 surface to act in such a way that the fiber 1 parts from the blade edges. The covering 2 is thus cleanly removed without damage on the fiber 1. |
