Abstract
A spooling drum for spooling multiple layers of wire rope or cable and having a structure preventing localized wear or crushing of the wire rope, the spooling drum including a cylindrical core and a stepped flange at each end of the core. The stepped flanges include one or more steps which support a riser having a tapered end which functions to receive the end wind of the wire rope as the drum rotates and to lift the rope to the next higher level of wind to thereby facilitate formation of a subsequent layer of wound wire rope. The risers supported by the steps of the flanges function to prevent wear of the cable caused by potential pinching of the cable against the flanges, and the steps facilitate the use of risers for any number of layers and avoid interference by the risers with orderly layered winding or spooling operations.
