ABSTRACT:
A picking controller capable of automatically controlling the retaining member of the weft yarn measuring and storing unit of a picking device and the modes of operation of subnozzle groups respectively composed of subnozzles detects an actual arrival phase at which a picked weft yarn arrives at a fixed position on the arrival side of the loom, and then compares the actual arrival phase with a reference arrival phase to obtain the angular difference between the actual arrival phase and the reference arrival phase. The controller then determines a picking phase on the basis of the angular difference, and determines a releasing phase at which the retaining member is to be retracted so as to release the weft yarn stored on the measuring and storing drum of the weft yarn measuring and storing unit. The controller then determines jet starting phases and jet ending phases respectively for the groups of subnozzles on the basis of the running characteristics of the picked weft yarn, and controls the groups of subnozzles on the basis of the jet starting phases and the jet ending phases for sequential jetting.
