Control system on a weaving loom having weft projection from a four section magazine is connected from the pattern card to the springs of the weft change mechanism. By means of punched card and selectors, along with a four cam drive, intermediary fork selectors pick up the mainshaft drive to one of two radial arms, which have a spring loaded relay to each of the two-way springs of the weft change mechanism.
