PURPOSE:To prevent the obstruction for sensing and the obstruction for position precision due to fibrous broken pieces by cutting-working a film having anisotropy along an extension axis and cutting a working port, thus removing the fibrous broken pieces. CONSTITUTION:An isotropic film to be cut-worked is prepared by extending the plastic film made of polyethylene, polyetster, etc. in the direction of one axis. Said anisotropic film is punched-out by the cutting mold means such as punching-out cutter and rotary cutter, or cutting-worked through traveling so that at least one cutting port is formed along the extension axis of the film. The film pieces or worked films consisting of the anisotropic films thus cutting-worked are superposed one by one or into plural pieces in a same-shaped article, and a cutting-work port is cut, and the fibrous broken pieces are cutting- removed. |
