<p>The disclosure of the present invention provides a central arbor for supporting three or more outer segments which are displaceable radially to effect an expansion and collapsing of the reeling surface during the process of winding up or paying off rolled steel strip. The radial displacement of the segments is accomplished by several readily replaceable and interchangeable wedge insert assemblies arranged between the arbor and segments. Each wedge assembly includes two cooperative wedge elements, one being arranged with one of the segments and the other with the arbor, the arbor being moved axially to effect a movement of the cooperative wedges.</p> |
