Abstract
In a fluid jet loom, almost all the faulty picks are attributable to defects in the quality of the weft yarn. The present invention detects matters for evaluating the physical properties of the weft yarn or matters for evaluating the result of the picking operation during the picking operation, discriminates the quality of the yarn package on the basis of data obtained through the detection, and automatically changes the yarn package for a new yarn package when it is decided that the yarn package feeding the weft yarn at present is defective.
