<p>The object of the invention is to prevent bending of an optical fiber and dislodging of a reinforcing rod. A protection sleeve includes a heat shrinkable tube and an adhesive tube and a reinforcing rod housed inside the heat shrinkable tube. The heat shrinkable tube, the adhesive tube, and the reinforcing rod are adhered together in a section spanning across a lengthwise section of the heat shrinkable tube. A protection sleeve manufacturing apparatus includes a jig for securing protection sleeves and a heating device. The jig is contrived to hold a plurality of protection sleeves (each of which includes a heat shrinkable tube and an adhesive tube and a reinforcing rod housed inside the heat shrinkable tube) in a parallel arrangement with spaces in-between. The heating device includes a plurality of hot air vents, a means of setting a distance between the jig and the hot air vents to a first distance, and a means of setting the jig and the hot air vents to a second distance that is closer than the first distance.</p> |
