ABSTRACT:
A compound elastomeric sleeve is provided for installation onto a segmented reel for preventing creases in metal strip wound into coil form thereon. A relatively thin, easily compressible outer sleeve is bonded to a thicker, more rigid inner sleeve. The dual hardness compound sleeve prevents creases yet retains its shape sufficiently for easy removal of a coil wound thereon from the reel. The invention includes a method for preventing creases from forming in metal strip which is to be wound into coil form on a segmented reel on which the compound sleeve is mounted.
