Abstract
A picking control apparatus for providing stable picking operation in a jet loom. The apparatus comprises an angle correcting section for outputting an angle correction amount of a picking start angle on the basis of an arrival angle deviation of filling yarn and a pressure correcting section for outputting a pressure correction amount of an injection pressure in a locking nozzle on the basis of a flying term deviation of filling yarn. The angle correcting section promptly corrects and controls a change of an arrival angle caused by a variation of flying characteristic of filling yarn, and thereafter the pressure correcting section corrects and controls a flying term so as to be adjusted to a set value. As a result, a stable picking operation in which only the picking start angle is not excessively deviated can be accomplished.
