<p>A weft detaining device (6, 6', 6") of shuttleless loom, comprises a drum (20, 54) having a frustoconical section (20a, 54c) and a cylindrical section (20b, 54d), a first catching member (31, 71) 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 (32, 72) 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 (33, 73) 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.</p> |
