An elastomeric sleeve adapted to be mounted on a reel for winding strip into coil form has metal inserts adjacent a gripper slot opening for preventing flat spots in the coil. The sleeve is designed to permit sufficient expansion when the reel is expanded so that the gripper opening is not pulled apart and a widened gap is not formed therebetween. Preferably, slits are provided on the inner periphery of the sleeve for this purpose. Alternatively, a collar can be mounted on the outboard end of the segment bridging the gripper opening for enhanced structural rigidity to prevent the sleeve from pulling apart the gripper opening upon expansion of the reel.
