ABSTRACT:
In a fluid jet loom, a weft inserting condition such as a fluid jet pressure is controlled by a feedforward control in which a change of a weft yarn condition due to interaction between the weft yarn and fluid jet is detected, and an anticipating corrective action is taken before the weft yarn is allowed to move into the shed.
