A strip accumulator for supporting a continuous length of strip material includes a plurality of circumferentially spaced stationary idler rolls for supporting an inner bundle of convolutions of the strip material on edge and an outer rotatable table surrounding the stationary idler rolls for supporting an outer bundle of such strip convolutions on edge. During overspeed filling of the accumulator, lifters are activated to facilitate transfer of the convolutions from the inner bundle to the outer bundle. Circumferentially spaced, radially extending skid bars may be provided on the upper surface of the rotatable table to reduce drag on the strip material during such transfer of the strip material from the stationary idler rolls to the rotatable table during overspeed filling of the accumulator. When the accumulator is filled to the desired capacity, the lifters are lowered out of the way so as not to interfere with the smooth transfer of the convolutions from the outer bundle to the inner bundle. Relatively short rods or bars are provided in the gap between the rotatable table and stationary idler rolls to prevent irregular or bent strip from getting hung up in the gap during transfer of the strip material from the rotatable table to the stationary idler rolls.
