Abstract: PURPOSE: To easily and appropriately support a wound roll by providing a spindle with a hollow support member having a longitudinal moving member inside, and pressure-supporting one end of the longitudinal moving member to a wound roll conveying device, while providing the other end with a valve for pressing a pressure medium into a bellows member of the spindle. CONSTITUTION: A spindle for supporting a tape roll 21 on a tape wound spool 20 is provided with a hollow support member 10 having a longitudinal moving member 11 inside. The longitudinal moving member 11 is provided with an outer part 11A and an inner part 11B having chucking parts 12 at the free ends. The spindle 7 is provided with a bellows member 13, and a bendable part 14 is provided on the inner surface of the bellows member 13. One end of the longitudinal moving member 11 is pressure-supported to a support plate member 16 of the roll conveying device by a spring 15, and the other end is provided with a valve 17 for pressing a pressure medium into the bellows member 13. Spindles 7', 7" in the resting state and operating state are respectively positioned as in the upper and lower half parts of a center line M.
