<p>PURPOSE:To prevent the dmage of the tube surface by electrically confirming a state that the tip of a needle-like cutting edge penetrates a protective cover and is in contact with the tube surface and peeling removing only the cover under a state that the contact of the tip is released. CONSTITUTION:A covered tube is positioned and pinched between a tube receiving section 2 and a tube suppressing section 3. The tip of a push rod 6 is brought into contact with the tube, a screw 9 is rotated, and the tip of a needle- like cutting edge 8 penetrates a cover and is brought into contact with the tube surface. This state is indicated by the excitation of a buzzer 10. The cutting edge 8 is retreated with a screw 9 until the buzzer 10 is stopped ringing, the whole instrument is rotated once around the tube, and the cover is peeled off without damaging the tube.</p> |
