Device with retractable anti-roll means, and use thereof in wire dispensing reels

The invention a device with retractable anti-roll means designed in particular for a wire dispensing reel (10) having a cylindrical body (11) and end flanges (12, 13). The end flange (12) comprises a circular peripheral rolling edge (2) provided with slots (15a-15f) wherein slide elastic blades (5a-5f) the ends of which constitute retractable radial anti-roll projections (3a-3f). The elastic blades (5a-5f) are integral with a coaxially operated ring (4) whereof the rotation enables to project or retract the radial anti-roll projections (3a-3f). Thus it is possible to selectively allow the reel to turn by retracting the radial anti-roll projections (3a-3f), or to lock the reel in rotation by extending the radial anti-roll projections (3a-3f)
