METHOD OF PRODUCING AN EXTRUDATE HAVING CONTROLLED SHAPE AND SIZE ABSTRACT OF THE DISCLOSURE A method of producing an extrudate is disclosed in which on-line adjustments are made to size and shape devia- tions by varying the temperature conditions in the extruder and by varying the relative speeds along the extrusion line. The temperature conditions can be adjusted by varying the temperature of the stock while maintaining a fixed relation- ship of the die temperature to the stock temperature to pro- duce deviations in the thickness of the extrudate with respect to the width of the extrudate, and by varying the temperature of the die with respect to the temperature in the stock to produce variations in different thicknesses of the extrudate. The relative speeds along the extrusion line can be varied by changing the speed of the screw in a cold-feed extruder, by changing the feed rate for a hot-feed extruder, or by changing the speed of the take-away device which regu- lates the speed by which the extrudate is taken away from the extruder.
