Abstract
A measuring and detecting device for determining the position of a break in a warp thread on a weaving machine. The machine makes possible a determination as to which side of the device the break is situated, what distance from the device the break is situated, and whether a broken warp thread has come free or has become entangled. The device includes thread guides placed at a distance from each other which can be presented against the warp thread, a mechanism for gripping the broken warp thread and drawing it between the thread guides, measuring devices mounted on the thread guides or on the gripping mechanism, and a processing unit for processing data obtained from the measuring devices.
