Abstract
A method and apparatus for off-line testing and correcting the metering accuracy of a split multihole spinneret fed by a single metered stream by determining end to end variations in flow rate and by reworking a number of holes in the lower flow rate side of the split spinneret, calculated by multiplying the average test percent bias of the split spinneret by a predetermined constant, so as to bring end to end variations in flow rate to within a required accuracy.
