A METHOD OF EVALUATING CRIMP IN TOW WHICH COMPRISES PASSING A BAND OF MOVING CRIMPED TOW THROUGH THE NIP FORMED BETWEEN A PAIR OF TENSIONING ROLLS MOVING COUNTERDIRECTIONALLY AT A SUBSTANTIALLY CONSTANT SPEED MATCHING THAT OF SAID MOVING TOW, PASSING SAID TOW BETWEEN THE NIP FORMED BETWEEN A PAIR OF RELAXING ROLLS MOVING COUNTERDIRECTIONALLY AT A SUBSTANTIALLY CONSTANT SPEED LESS THAN THAT OF SAID TENSIONING ROLLS, DEFLECTING SAID TOW BETWEEN SAID TENSIONING ROLLS AND SAID RELAXING ROLLS BY PASSING IT PARTLY AROUND A TENSION-SENSING ROLLER AND THEREBY EXERTING A FORCE COMPONENT ON THE ROLLER PROPORTIONAL OF THE TOW TENSION, AND MEASURING SAID FORCE COMPONENT AND THEREBY INDICATING THE AVERAGE ANGLE AND AMOUNT OF CRIMP IN SAID TOW.
