Abstract
A weft detaining device of a shuttleless loom, comprises a drum on which a weft yarn is wound predetermined times prior to a weft picking through a weft picking means, the drum being constituted by a plurality of separate and independent pieces, a support member on which the drum separate pieces are securely supportable, and a device for allowing the location of each drum separate piece to be movable relative to the support member so that the outer diameter of the drum is adjustable, thereby making possible changing a weft picking length by merely changing the location of each drum separate piece, without replacing the drum with the other drum having a different diameter or using any members to be mounted on the peripheral surface of the drum to adjust the outer diameter of the drum.
