Claim 1
Independent Claim
120 words
A METHOD FOR THE SIMULTANEOUS MEASUREMENT OF FRICTIONAL PROPERTIES AND STATIC GENERATION RATE OF YARNS OVER SUBSTANTIALLY THE ENTIRE RANGE OF TENSIONS AND SPEEDS UTILIZED IN THE TEXTILE PROCESSING YARNS WHICH COMPRISES FORWARDING SAID YARN AT A CONTROLLABLE, PREDETERMINED RATE OF SPEED WITHIN A PREDETERMINED SPEED RANGE, PLACING ON SAID YARN A PREDETERMINED INPUT TENSION WITHIN A PREDETERMINED TENSION RANGE, MEASURING SAID PREDETERMINED INPUT TENSION, PASSING SAID YARN OVER A STATIONARY, SNUBBING TEST SURFACE, MEASURING AND RECORDING THE STATIC CHARGE DEVELOPED BY SAID YARN PASSING OVER SAID STATIONARY, SNUBBING TEST SURFACE, MEASURING THE OUTPUT TENSION ON SAID YARN AT A POINT AFTER SAID YARN HAS PASSED OVER SAID STATIONARY, SNUBBING TEST SURFACE AND RECORDING SAID MEASURED INPUT AND OUTPUT TENSIONS.
