Abstract: A control device for actuating the weft carriers attached to opposed flexible tapes in a shuttleless loom. One end of each tape is attached to a driving arm with the opposite ends of the latter being fixed on oscillatably driven hub members. One side of each hub member has a disc element mounted thereon for movement therewith. The periphery of the disc members are disposed in operative association with the ends of the driving arms to which the tapes are attached and define platforms onto which the tapes are wrapped and unwrapped during their withdrawal from and insertion into a shed of warp threads by the driving arm.
