Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
134 words
A NUBBED YARN COMPRISING AT LEAST ONE CORE STRAND AND AT LEAST ONE WRAPPING STRAND, SAID WRAPPING STRAND BEING INTIMATELY ASSOCIATED WITH SAID CORE STRAND AND POSSESING NO NET TRUE TWIST ABOUT LOOPS WOUND FOR A MULTIPLICITY OF TURN AROUND SAID CORE STRAND AND POSSESSING NO NET TRUE TWIST ABOUT SAID CORE STRAND, THE WRAPPED CORE STRAND BEING AT SPACED-APART INTERVALS TWISTED INTO PEDICLED LOOPS, THE CORE STRAND CONSTITUTING SAID PEDICLE LOOPS BEING ASSOCIATED WITHIN SAID PEDICLED LOOPS , IN ENTANGLED RELATIONSHIP WITH SAID BIFILAR LOOPS OF WRAPPING STRAND, SAID PEDICLED LOOPS OF CORE STRAND, TOGETHER WITH THE WRAPPING STRAND ASSOCIATED THEREWITH WITHIN SAID PEDICLED LOOPS CONSTITUTING A SERIES OF NUBS SPACED ALONG THE LENGTH OF THE COMPOSITE YARN, SAID NUBS BEING CHARACTERIZED BY SUBSTANTIAL RESISTANCE TO DISPLACEMENT ALONG THE LENGTH OF SAID YARN.
Claim 2
Dependent Claim
134 words
A NUBBED YARN COMPRISING AT LEAST ONE CORE STRAND AND AT LEAST ONE WRAPPING STRAND, SAID WRAPPING STRAND BEING INTIMATELY ASSOCIATED WITH SAID CORE STRAND AND POSSESING NO NET TRUE TWIST ABOUT LOOPS WOUND FOR A MULTIPLICITY OF TURN AROUND SAID CORE STRAND AND POSSESSING NO NET TRUE TWIST ABOUT SAID CORE STRAND, THE WRAPPED CORE STRAND BEING AT SPACED-APART INTERVALS TWISTED INTO PEDICLED LOOPS, THE CORE STRAND CONSTITUTING SAID PEDICLE LOOPS BEING ASSOCIATED WITHIN SAID PEDICLED LOOPS , IN ENTANGLED RELATIONSHIP WITH SAID BIFILAR LOOPS OF WRAPPING STRAND, SAID PEDICLED LOOPS OF CORE STRAND, TOGETHER WITH THE WRAPPING STRAND ASSOCIATED THEREWITH WITHIN SAID PEDICLED LOOPS CONSTITUTING A SERIES OF NUBS SPACED ALONG THE LENGTH OF THE COMPOSITE YARN, SAID NUBS BEING CHARACTERIZED BY SUBSTANTIAL RESISTANCE TO DISPLACEMENT ALONG THE LENGTH OF SAID YARN.
Claim 3
Dependent Claim
93 words
A PROCESS FOR PRODUCING A WRAPPED NUBBED YARN WHICH COMPRISES CONTINUOUSLY OVERFEEDING A CORE STRAND INTO A VORTEX CELL CONTAINING A WHIRLING MASS OF FLUID, IN A DIRECTION NORMAL TO SAID WHIRLING MASS, CONTINUOUSLY OVERFEEDING AT LEAST ONE WRAPPING STRAND TO SAID VORTEX CELL IN A DIRECTION TANGENTIAL TO SAID WHIRLING MASS OF FLUID, CONTINUOUSLY WRAPPING SAID WRAPPING STRAND IN THE FORM OF DOUBLE-BACK LOOPS AROUND SAID CORE STRAND, CONTINUOUSLY TWISTING THE THUS-WRAPPED OVERFED CORE STRAND INTO A SPACED-APART SERIES OF TWISTED LOOPS, AND CONTINUOUSLY REMOVING SAID WRAPPED NUBBED YARN FROM SAID CELL.
Claim 4
Dependent Claim
93 words
