ABSTRACT:
A picking control device for a loom comprising a pressure controller for controlling jet pressure of a picking nozzle, a timing controller for controlling operation time of a picking member, angle corrector for correcting the start angle of the weft yarn and a condition setting section which is operated on the condition that one of the signals from the pressure controller or angle corrector is not present so that at least one of the jet pressure, start angle or speed of the loom is maintained at an optimum value. This allows for effective picking with adequate air consumption and helps to prevent weaving defects such as cutting of the weft yarn at the time of termination of picking, warp engagement and the like.
