PURPOSE:To obtain a method for feeding a light transmission wire of a long feedable distance and high feeding speed by preventing electrification to remove charges on at least either surface of the surface of this light transmission wire or the inside surface of a plastic tube. CONSTITUTION:The charges on at least either surface of the front surface of the light transmission wire or the inside surface of the plastic tube are removed or the electrification thereof is prevented in the method for feeding the light transmission wire into the plastic tube by flow of gas by passing this gas into the plastic tube from its one end to the other end. The methods for removing the charges or preventing the electrification are executed by passing the gas into which moisture is included or the ionized gas into the plastic tube or blowing the ionized gas to the surface of the light transmission wire or applying an antistatic agent thereon, etc. As a result, the attraction force by the static electricity of the light transmission wire with the plastic tube is eliminated or made small and, therefore, the feeding of the light transmission wire even into the fine plastic tube is possible. |
