Abstract
A weft inserting control device for fluid jet type loom is provided, including a weft insertion detecting unit for detecting dispersion of the weft reaching angle in a predetermined control cycle; a first comparing unit for comparing a detection value of the weft reaching angle given by the weft insertion detecting unit with a reference value showing an allowable range of the dispersion; and a second comparing unit for comparing the detection value with a threshold value showing a threshold in controlling the dispersion. The weft inserting control device also includes a controlling unit for controlling the weft reaching angle on the basis of the detection value and a result of the comparison carried out by the first comparing unit. The controlling unit controls the weft reaching angle by reducing a predetermined amount of the detection value and by using the threshold value as the detection value, for example, when the second comparing unit reveals the detection value to be over the threshold value.
