Stretch novelty yarn and method of making same

Claim 1

A COMPOSITE STRETCH NOVELTY YARN COMPRISING A TAUT, STRAIGHT NON-ELASTIC CORE THREAD, AN UNTENSIONED NON-ELASTIC THREAD WRAPPED ABOUT SAID CORE THREAD IN ONE DIRECTION, SLIDABLE THEREALONG AND BULGING OUTWARDLY THEREFROM IN A SERIES OF NODE-LIKE FORMATIONS THAT PRODUCE THE CHARACTERISTIC NOVELTY EFFECT, AND AN INITIALLY STRETCHED ELASTIC THREAD TWISTED IN THE OPPOSITE DIRECTION WITH SAID COMBINED NON-ELASTIC THREADS TO FORM THE FINISHED COMPOSITE YARN, SAID ELASTIC THREAD BEING OPERATIVE TO BIND SAID EFFECT THREAD TO SAID CORE THREAD AND SECURE THE SAME AGAINST SLIDING THEREALONG, SAID COMBINED NON-ELASTIC THREADS BEING ADAPTED TO BULGE OUTWARDLY IN A SERIES OF NODE-LIKE LOOPS WHEN SAID COMPOSITE YARN IS PERMITTED TO RELAX.

Claim 3

A METHOD OF PRODUCING COMPOSITE STRETCH NOVELTY YARNS WHICH COMPRISES ADVANCING A CORE THREAD INTO A TWIST ZONE, ADVANCING A NON-ELASTIC EFFECT THREAD INTO SAID TWIST ZONE AND WRAPPING THE SAME ABOUT SAID CORE THREAD SO THAT THE AVERAGE DIAMETER OF WRAP IS SUBSTANTIALLY LARGER THAN THE DIAMETER OF THE PORTION OF SAID CORE THREAD WITHIN THE WRAPS, ADVANCING THE COMBINED CORE AND EFFECT THREADS INTO A SECOND TWIST ZONE, AND ADVANCING A TENSIONED ELASTIC THREAD INTO SAID SECOND TWIST ZONE AND TWISTING IT WITH THE COMBINED CORE AND EFFECT THREADS SO THAT THE EFFECT THREAD WILL BE HELD ABOUT SAID CORE THREAD AND SECURED AGAINST SLIDING THEREALONG SOLELY BY THE INTERTWIST OF SAID COMBINED CORE AND EFFECT THREADS AND SAID ELASTIC THREAD, SO THAT WHEN SAID COMPOSITE YARN IS ELONGATED SAID COMBINED CORE AND EFFECT THREADS AND SAID ELASTIC THREAD ARE ARRANGED IN TIGHT PLY FORMATION, AND SO THAT WHEN SAID COMPOSITE YARN IS PERMITTED TO RELAX SAID COMBINED CORE AND EFFECT THREADS BULGE OUTWARDLY FROM SAID ELASTIC THREAD.

Claim 4

A METHOD OF PRODUCING COMPOSITE STRETCH NOVELTY YARNS WHICH COMPRISES ADVANCING A CORE THREAD INTO A TWIST ZONE, ADVANCING A NON-ELASTIC EFFECT THREAD INTO SAID TWIST ZONE AND WRAPPING THE SAME ABOUT SAID CORE THREAD SO THAT THE AVERAGE DIAMETER OF WRAP IS SUBSTANTIALLY LARGER THAN THE DIAMETER OF THE PORTION OF SAID CORE THREAD WITHIN THE WRAPS, ADVANCING THE COMBINED CORE AND EFFECT THREADS INTO A SECOND TWIST ZONE, AND ADVANCING A TENSIONED ELASTIC THREAD INTO SAID SECOND TWIST ZONE AND TWISTING IT WITH THE COMBINED CORE AND EFFECT THREADS SO THAT THE EFFECT THREAD WILL BE HELD ABOUT SAID CORE THREAD AND SECURED AGAINST SLIDING THEREALONG SOLELY BY THE INTERTWIST OF SAID COMBINED CORE AND EFFECT THREADS AND SAID ELASTIC THREAD, SO THAT WHEN SAID COMPOSITE YARN IS ELONGATED SAID COMBINED CORE AND EFFECT THREADS AND SAID ELASTIC THREAD ARE ARRANGED IN TIGHT PLY FORMATION, AND SO THAT WHEN SAID COMPOSITE YARN IS PERMITTED TO RELAX SAID COMBINED CORE AND EFFECT THREADS BULGE OUTWARDLY FROM SAID ELASTIC THREAD.
