ABSTRACT:
A weft insertion control apparatus for a multi-color jet loom comprises a plurality of solenoid valves for controlling supply of a pressurized fluid to weft inserting auxiliary nozzles, an on/off controller for controlling these valves independently of one another, a first memory for storing a weft color selection pattern, and a second memory for storing on/off timing for the individual valves on a weft basis. The on/off controller reads out the weft color selection pattern stored in the first memory for every rotation of the loom and selects the preset on/off timing from the second memory on the basis of the result of the reading thereby controlling the valves.
