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 ( 15 a -15 f) wherein slide elastic blades ( 5 a -5 f) the ends of which constitute retractable radial anti-roll projections ( 3 a -3 f). The elastic blades ( 5 a -5 f) are integral with a coaxially operated ring ( 4 ) whereof the rotation enables to project or retract the radial anti-roll projections ( 3 a -3 f). Thus it is possible to selectively allow the reel to turn by retracting the radial anti-roll projections ( 3 a -3 f), or to lock the reel in rotation by extending the radial anti-roll projections ( 3 a -3 f)
