Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
124 words
AN APPARATUS FOR TEXTURIZING A RUNNING LENGTH OF CONTINUOUS FILAMENT THERMOPLASTIC YARN COMPRISING A BLADE ASSEMBLY HAVING AT LEAST ONE PAIR OF OPPOSED BLADES HAVING SHARPENED EDGE PORTIONS, ONE OF SAID BLADES BEING POSITIONED TO EFFECT A SUDDEN CLOCKWISE CHANGE OF DIRECTION IN SAID YARN PATH, THE OTHER OF SAID BLADES BEING POSITIONED TO EFFECT A SUDDEN COUNTER-CLOCKWISE CHANGE IN DIRECTION OF SAID YARN PATH, EACH OF SAID BLADE PORTIONS BEING DISPOSED AT THE APEX OF THE ANGLE DESCRIBED BY THE CHANGES IN DIRECTION OF THE YARN PATH, SAID EDGE PORTIONS OF SAID PAIR OF BLADES LYING IN INTERSECTING PLANES HAVING A COMMON PERPENDICULAR, WHEREBY A YARN PASSING UNDER TENSION BETWEEN SAID BLADES EDGES IS SUBJECTED TO A FALSE-TWIST TO PROVIDE A HIGH-BULK YARN.
Claim 2
Independent Claim
124 words
AN APPARATUS FOR TEXTURIZING A RUNNING LENGTH OF CONTINUOUS FILAMENT THERMOPLASTIC YARN COMPRISING A BLADE ASSEMBLY HAVING AT LEAST ONE PAIR OF OPPOSED BLADES HAVING SHARPENED EDGE PORTIONS, ONE OF SAID BLADES BEING POSITIONED TO EFFECT A SUDDEN CLOCKWISE CHANGE OF DIRECTION IN SAID YARN PATH, THE OTHER OF SAID BLADES BEING POSITIONED TO EFFECT A SUDDEN COUNTER-CLOCKWISE CHANGE IN DIRECTION OF SAID YARN PATH, EACH OF SAID BLADE PORTIONS BEING DISPOSED AT THE APEX OF THE ANGLE DESCRIBED BY THE CHANGES IN DIRECTION OF THE YARN PATH, SAID EDGE PORTIONS OF SAID PAIR OF BLADES LYING IN INTERSECTING PLANES HAVING A COMMON PERPENDICULAR, WHEREBY A YARN PASSING UNDER TENSION BETWEEN SAID BLADES EDGES IS SUBJECTED TO A FALSE-TWIST TO PROVIDE A HIGH-BULK YARN.
Claim 3
Dependent Claim
88 words
IN A METHOD OF TEXTURIZING A RUNNING LENGTH OF THERMOPLASTIC YARN CHARACTERIZED BY THE STEPS OF CONTINUOUSLY PASSING SAID YARN ABOUT A FIRST BLADE EDGE THROUGH A SUDDEN CHANGE IN DIRECTION, THENCE PASSING SAID YARN ABOUT A SECOND BLADE EDGE THROUGH A SUDDEN CHANGE IN DIRECTION OF OPPOSITE SENSE TO THAT CHANGE IN DIRECTION ABOUT SAID FIRST BLADE EDGE; THE IMPROVEMENT COMPRISING, IMPARTING A FALSE-TWIST TO SAID YARN INTERMEDIATE SAID FIRST AND SECOND BLADE EDGES TO THEREBY IMPROVE THE BULKING ACTION OF SAID BLADE EDGES ON SAID YARN.
Claim 4
Dependent Claim
88 words
IN A METHOD OF TEXTURIZING A RUNNING LENGTH OF THERMOPLASTIC YARN CHARACTERIZED BY THE STEPS OF CONTINUOUSLY PASSING SAID YARN ABOUT A FIRST BLADE EDGE THROUGH A SUDDEN CHANGE IN DIRECTION, THENCE PASSING SAID YARN ABOUT A SECOND BLADE EDGE THROUGH A SUDDEN CHANGE IN DIRECTION OF OPPOSITE SENSE TO THAT CHANGE IN DIRECTION ABOUT SAID FIRST BLADE EDGE; THE IMPROVEMENT COMPRISING, IMPARTING A FALSE-TWIST TO SAID YARN INTERMEDIATE SAID FIRST AND SECOND BLADE EDGES TO THEREBY IMPROVE THE BULKING ACTION OF SAID BLADE EDGES ON SAID YARN.
