ABSTRACT:
Methods are provided for imparting a grooved surface to cable drums for winding in spaced fashion rope, wire or cable onto the drum surface without the need for expensive machining operations. This is achieved by providing elongated strands of material, preferably comprised of a synthetic thermoplastic resin, with the strands having a cross sectional profile which includes a rope-receiving groove on one surface thereof. Subsequently, one or more lengths of the strands are coiled and fastened to the drum core surface to impart thereto a continuous groove for receiving the rope or cable coiled thereon. The side edges of the strand profile may be configured so that when coiled on the drum surface, adjacent side edges of the coil interlock so as to maintain adjacent coils firmly in place against each other. Moreover, the strands forming the grooved drum surface may incorporate wire mesh, wire, or metal or textile webs to reduce elongation thereof in use.
