METHOD AND DEVICE FOR INSTALLING MARK TUBE FOR ELECTRIC WIRE

摘要

PURPOSE:To completely automate an operation for installing a mark tube by insertion of a wire into the mark tube by preventing the wire from being hooked. CONSTITUTION:A wire 11 is tapered. The narrowest portion of the wire 11 is positioned on the axis of a mark tube 14 and opposed to the mark tube 14. The wire 11 and the mark tube 14 are positioned on the same axis and the wire 11 is passed through the mark tube 14. Curving of the wire is allowed only between the tapered end of the wire 11 and the inner peripheral surface of the mark tube 14 and complete automation can be achieved without the possibility of the wire being hooked during installation.
