Weft detaining device of shuttleless loom

A weft detaining device of a shuttleless loom having a weft inserting nozzle for picking a weft yarn from a weft source, comprising:

• a stationary drum formed on its peripheral surface with first and second holes, said first hole being located farther from the weft inserting nozzle than said second hole in the axial direction of said drum;
• a weft wind-guide member located near the peripheral surface of said drum and rotatable around the drum peripheral surface in timed relation to the operational cycle of the loom to guide the weft yarn between the weft inserting nozzle and the weft source to be wound around the peripheral surface of said drum;
• first and second hook levers located outside of said drum and formed respectively with first and second hook sections which are capable of projecting respectively into said first and second holes of said drum to catch the weft yarn on the drum peripheral surface so as to prevent the weft yarn from moving, a predetermined length of the weft yarn for each weft picking being detained between said projected first and second hook sections;
• and
• means for causing said first and second hook sections to project respectively into the first and second holes of the drum at predetermined timings in timed relation to the operational cycle of the loom.
