ABSTRACT:
In operation control of a plurality of weft reservoirs for freely changeable alternate weaving, winding and delivering functions are separately controlled by a central processing unit electrically connected to yarn guide drive motors and control pin drive solenoids on the weft reservoirs in order to avoid need for advanced sequence adjustment between the weft reservoirs. The winding function is controlled in response to a count-up signal combined with a delivery-over signal both quite unrelated to loom operational sequence whereas the delivery function is controlled in response to a clock-pulse combined with a weft-insertion command both closely related to the loom operational sequence.
