Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
66 words
A PROCESS FOR MAKING BULKY CONTINUOUS YARN FOR A BUNDLE OF SUBSTANTIALLY STRAIGHT CONTINUOUS FILAMENTS WHICH COMPRISES PASSING THE FILAMENT BUNDLE THROUGH A FLUID JET, JETTING THE FLUID WITH SUFFICIENT FORCE TO SEPARATE THE FILAMENTS AND FORM THE FILAMENTS INDIVIDUALLY INTO CONVOLUTIONS AND REMOVING THE FILAMENTS FROM THE JETTED FLUID AND COMBINING THE CONVOLUTED FILAMENTS INTO A YARN WHILE AVOIDING TENSION SUFFICIENT TO REMOVE THE CONVOLUTIONS.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
68 words
APPARATUS FOR MAKING BULKY CONTINUOUS FILAMENTS YARN WHICH COMPRISES A FLUID NOZZLE ADAPTED TO CREATE A TURBULENT ZONE, MEANS FOR FEEDING YARN CONTINUOUSLY THROUGH THE TURBULENT ZONE, MEANS FOR SUPPLYING FLUID TO SAID NOZZLE UNDER A PRESSURE WHICH WILL PROVIDE SUFFICIENT TURBULENE TO SEPARATE THE YARN FILAMENTS AND FORM THEM INTO CONVOLUTIONS, AND MEANS FOR WITHDRAWING THE SEPARATED FILAMENTS FROM THE TUBULENT ZONE AND REFORMING THEM INTO YARN.
