A selector mechanism which can be installed directly in a loom in the path of the warp threads, which is able to control the position of a single warp thread to be at the correct shed position for weft insertion according to an external mechanical signal. The selector consists of a heddle (4, 22) which has an open slot (5), or more than one open slot (23, 24) for three or more shed positions, rather than a closed eye, and which oscillates at loom speed, and of other components (5, 18, 20). The other components determine whether the warp thread is retained at one of the extremes of the shed position, or is inserted into an open slot in the heddle and so is positioned by the heddle. The timing of the weaving process is such that weft insertion occurs proximal to the heddle reaching a point furthest from the warp retention point on the other components.
