Abstract
A weft inserting control device for a fluid jet type loom for detecting dispersion of a weft reaching angle to control the reaching angle of weft yarn. The device includes a weft insertion detecting unit for detecting dispersion of the weft reaching angle in a plurality of control cycles such as a plurality of picking numbers, for example. The device also includes a controlling unit for comparing a plurality of detection values of the weft reaching angle given by the weft insertion detecting unit with a plurality of respective different reference values, and for controlling the weft reaching angle on the basis of a result of the comparison in every control cycle.
