JIG FOR INSTALLING FLEXIBLE TUBE

摘要

PROBLEM TO BE SOLVED: To provide a jig for installing a flexible tube in which a flexible tube is economically covered on a supporting drum without lengthening a length of the supporting drum. SOLUTION: A supporting drum is provided with a retaining body 11 constituted by a cylindrical body portion 12 having a cross section of a reverse C shape, an intermediate portion 13 of a top-cut cone shape integrally and continuously formed on a lower end of the body portion 12 and having a wrung lower side so as to make an outer periphery wall 13a to a taper surface such that a diameter is gradually varied from a slightly bigger diameter than an inner diameter of a flexible tube to a smaller diameter than that, and a cylindrical lower end portion 14 integrally and continuously formed on a lower end of the intermediate portion 13. When the flexible tube is retained by inserting the lower end portion 14 and the intermediate portion 13 of the retaining body 11 to the one end inside of the flexible tube, a gas is blown from a gas injection port to the inside of the flexible tube through a gas introducing passage on the retaining body 11.
