Rope strand and method for making same

Claim 1

A ROPE STRAND COMPRISING A CORE, SAID CORE INCLUDING A PLURALITY OF YARNS TWISTED ABOUT A COMMON AXIS AT A PREDETERMINED PITCH PER UNIT LENGTH, A LAYER OF INDIVIDUAL YARN ELEMENTS TWISTED ABOUT SAID COMMON AXIS ONTO AND ABOUT SAID CORE WHEREBY THE PITCH PER SAID UNIT LENGTH OF SAID LAYER OF YARN IS GREATER THAN THE PITCH PER UNIT LENGTH OF SAID CORE MEASURED ALONG SAID COMMON AXIS, SO THAT EACH YARN IN CORE AND THE YARNS OF SAID CORE COVERING LAYER REACH THEIR MAXIMUM ELONGATION AT THE BREAKING STRESS TO INSURE EACH OF SAID YARNS BEING UNIFORMLY STRESSED UNDER A GIVEN LOAD.

Claim 3

A METHOD OF MAKING A MULTIPLE LAYER ROPE STRAND COMPRISING THE STEPS OF DRAWING A PLURIALITY OF YARN FROM A SORUCE, TWISTING SAID YARNS AS THEY ARE DRAWN FROM THE SOURCE TO FORM TEH CORE OF SAID ROPE STRND, FORMING SAID TWIST SO AS TO HAVE A PREDETERMINATE PITCH PER UNIT LENGTH OF SAID CORE, SIMULTANEOUSLY PULLING ANOTHER PLURALITY OF YARN HAVING SUBSTANTIALLY SIMILAR ELASTROMETRIC PROPERTIES AS THE YARN FORMING SAID CORE FROM ANOTHER SORUCE, TWISTING SAID SECOND MENTIONED YARNS ABOUT SAID CORE TO FORM A COVERING LAYER THEREFOR AS SECOND CORE IS FORMED, AND FORMING THE TWIST OF SAID COVERING LAYER SO AS TO HAVE A PITCH PER SAID UNIT LENGTH WHICH IS GREATER THAT THE PITCH OF SAID CORE IN ONE CONTINUING OPERATION SO THAT THE RESPECTIVE YARNS OF SAID CORE AND COVERING ALYER ATTAIN SUBSTANTIAL EQUALITY IN LENGTH TO INSURE THAT EACH OF SAID YARNS IS UNIFORMLY LOADED WHEN STRESSED.

Claim 4

A METHOD OF MAKING A MULTIPLE LAYER ROPE STRAND COMPRISING THE STEPS OF DRAWING A PLURIALITY OF YARN FROM A SORUCE, TWISTING SAID YARNS AS THEY ARE DRAWN FROM THE SOURCE TO FORM TEH CORE OF SAID ROPE STRND, FORMING SAID TWIST SO AS TO HAVE A PREDETERMINATE PITCH PER UNIT LENGTH OF SAID CORE, SIMULTANEOUSLY PULLING ANOTHER PLURALITY OF YARN HAVING SUBSTANTIALLY SIMILAR ELASTROMETRIC PROPERTIES AS THE YARN FORMING SAID CORE FROM ANOTHER SORUCE, TWISTING SAID SECOND MENTIONED YARNS ABOUT SAID CORE TO FORM A COVERING LAYER THEREFOR AS SECOND CORE IS FORMED, AND FORMING THE TWIST OF SAID COVERING LAYER SO AS TO HAVE A PITCH PER SAID UNIT LENGTH WHICH IS GREATER THAT THE PITCH OF SAID CORE IN ONE CONTINUING OPERATION SO THAT THE RESPECTIVE YARNS OF SAID CORE AND COVERING ALYER ATTAIN SUBSTANTIAL EQUALITY IN LENGTH TO INSURE THAT EACH OF SAID YARNS IS UNIFORMLY LOADED WHEN STRESSED.
