Claims
- 1. A method for monitoring the uniformity of tows with mechanical sensing elements in the course of producing a tow line comprising the steps of transporting a tow at a predetermined speed by a roller arrangement, measuring tow tension upstream of the roller arrangement, detecting any irregularity of the tow passing the roller arrangement by detecting tow tension increases and decreases, establishing predetermined positive and negative tow tension thresholds, indicating an irregularity in the tow when the measured tension exceeds either threshold, and triggering fault measures when either threshold is exceeded.
- 2. A method as in claim 1 wherein the roller arrangement comprises the intake rolls of a tow treatment apparatus.
- 3. A method for monitoring the uniformity of tows with mechanical sensing elements in the course of producing a tow line comprising the steps of transporting a tow at a predetermined speed by a roller arrangement, measuring tow tension upstream of the roller arrangement, detecting any irregularity of tow passing the roller arrangement by detecting tow tension increases and decreases, counting the number of tow increases and decreases over the given length of tow, and utilizing the number of tow increases and decreases over the given length of tow as a measure of tow quality.
- 4. A method as in claim 3 wherein the roller arrangement comprises the intake rolls of a tow treatment apparatus.
