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

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