Abstract
A shuttleless loom incorporating a weft detecting device according to this invention includes a reed, and a number of guide plates arranged in spaced relationship along the reed, the guide plates being provided with aligned apertures to form a guide passage through which a weft is passed when it is inserted into a shed of warps. In order to detect whether or not the weft has been inserted into the shed, the weft detection device is provided with a photoelectric detecting unit disposed between the adjacent guide plates so as to be movable therewith. The detecting unit emits and receives a light beam advancing along a path which extends between the adjacent guide plates and across a path of the weft along which it moves relative to the guide plates after it has been passed through the guide passage.
