An apparatus for selecting inserting weft yarns each into a weaving shed of warp yarns in a shuttleless weaving loom, in which a fluid distributor valve unit, a weft feeding and length-measuring mechanism and a weft retaining unit are operated by levers selectively driven for rocking motion depending upon the angular positions of cams mounted in two groups on separate cam shafts which are rotatable independently of each other and which are driven to turn about the respective center axes of the cam shafts in accordance with a predetermined weaving schedule stored in, for example, a dobby mechanism.
