Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
87 words
THE METHOD OF PROCESSING THERMOPLASTIC YARN COMPRISING HEATING SAID YARN AND PASSING SAID YARN IN A HEATED STATE OVER AND PAST A SHARP-BEND SURFACE WITH A SHARP ANGLE OF BEND IN THE PATH OF SAID YARN AS IT PASSES OVER SAID BEND SURFACE, AND INTERMITTENTLY ALTERNING THE DEGREE OF HEATING OF SAID YARN SUBSTANTIALLY IMMEDIATELY PRECEDING PASSAGE OVER SAID BEND SURFACE WHEREBY SUCCEEDING INCREMENTS OF YARN PASSING OVER SAID BEND SURFACE ARE AT DIFFERENT TEMPERATURES AS THEY PASS OVER SAID BEND SURFACE AND ARE THEREBY DIFFERENTIALLY CRIMP-MODIFIED.
Claim 2
Independent Claim
87 words

Claim 3
Dependent Claim
112 words
APPARATUS FOR PROCESSING THERMOPLASTIC TEXTILE YARN COMPRISING A YARN SUPPLY SOURCE, A YARN TAKE-UP, A YARN CRIMPING DEVICE DISPOSED IN INTERMEDIATE FLOW RELATION BETWEEN SAID SUPPLY MEANS COMPRISING A SHARP-BEND CRIMPING YARN CRIMPING MEANS COMPRISING A SHARP-BEND CRIMPING ELEMENT DISPOSED IN YARN-BENDING RELATION AT A POINT ALONG THE PATH OF SAID YARN, HEATER MEANS DISPOSED IN SUBSTANTIALLY IMMEDIATE PRECEDING FLOW RELATION TO SAID YARN CRIMPING ELEMENT, AND MEANS FOR INTERMITTENTLY ALTERNING THE DEGREE OF HEATING OF SAID YARN BY SAID HEATING MEANS WHEREBY SUCCEEDING INCREMENTS OF YARN PASSING OVER SAID SHARP-BEND CRIMPING ELEMENT ARE AT DIFFERENT TEMPERATURES AS THEY PASS IN A SHARP BEND OVER SAID ELEMENT AND ARE THEREBY DIFFERENTIALLY CRIMP-MODIFIED.
