<p>A method for controlling the thickness or weight of extruded stock.
<??>An extruding system for the production of continuously extruded elastomer, such as tread stock for the manufacture of vehicle tires, has an extruder (12), a first take-away conveyor belt (16) for conveying the extrusion as it exits the extruder, a second conveyor belt (17) for varying the thickness or weight of the extrusion after leaving the first conveyor belt, a sensor (20) to measure the running-weigh-scale value and a targeted running-weigh-scale value. The weight or thickness of the continuously extruded elastomer is controlled by measuring the weight of the continuous extrusion at the running-weigh-scale. The measured value (RWS 20) is compared to the target value to obtain a control signal (38). The control signal (38) is used (40) to adjust the difference in speed between the first conveyor belt (16) and the second conveyor belt (17).</p> |
