A METHOD OF MEASURING THE DENIER OF TEXTILE THREAD, COMPRISING: LONGITUDINALLY MOVING THE THREAD BETWEEN TWO MEASURING FIELDS, THE LINES OF FLUX OF ONE MEASURING FIELD FORMING AN ANGLE WITH THE LINES OF FLUX OF THE SECOND MEASURING FIELD AND THE THREAD BEING LONGITUDINALLY MOVED AT A LOCATION DISTANT FROM THE APEX OF SAID ANGLE, SIMULTANEOUSLY RELATIVELY RECIPROCATING AT A PREDETERMINED FREQUENCY AND AMPLITUDE THE THREAD AND THE MEASURING FIELDS IN A DIRECTION NORMAL TO THE THREAD FOR ALTERNATING MOVING THE THREAD INTO AND OUT OF SAID MEASURING FIELDS AND ALTERNATELY INFLUENCING THE TWO MEASURING FIELDS BY THE THREAD, AND MEASURING THE EXTENT OF INFLUENCE OF THE THREAD ON SAID MEASURING FIELDS.
