cable is coreless with all of the filaments iadd rovings iaddend making up the cable at substantially the same helical angle and all filaments coated with a cured elastomeric sheath the preferred elastomers used in fabricating cables of this invention are urethane elastomers made by mixing a urethane prepolymer with a curing agent or hardener for the resin in predetermined quantities urethane resins of the type used are commercially available it was discovered that variations in the helical angle or lead at which the cables were fabricated gave a finished cable which under varying temperature conditions contracted under a given tensile load this was totally unexpected as most cable material conventionally used elongates with increasing temperature the discovery of this property of the cable led to the making of a cable which under widely varying temperature conditions maintains a substantially constant length by choosing a helical angle or lead within a designated range iadd and maintaining it constant during application of all layers of roving from the cable center to outer surface iaddend a cable can be plied which maintains a constant length over a wide range of temperature conditions fig1 of the drawings illustrates contraction of the composite cable of this invention at varying helical angles under temperatures ranging from 70 to 170 u00b0 f contrasted with elongation of other.
