A weft detaining device of a shuttleless loom, including a drum having a frustoconical section and a cylindrical section, a first catching member for catching the weft yarn on the drum in the vicinity of the border between the frustoconical and cylindrical sections for at least a period of weft pickings, a second catching member for catching the weft yarn on the drum for at least a period of the first time weft picking in sequential twice weft pickings and releasing its catching action to the weft yarn for at least a period of the second time weft picking of the sequential twice weft pickings, and a third catching member for catching the weft yarn on the drum cylindrical section for at least a period wherein the detaining of the weft yarn for the succeeding twice sequential weft pickings is completed, thereby enabling a so-called dual-pick pass weft insertion though the weft detaining device is of the drum type.
