Abstract

An apparatus for determining the location of a warp thread break in weaving looms using drop wires, including detection devices 6 to identify warp thread breaks, movable drop wire locators 7 to determine the warp thread break locations, switching devices 8 arranged to actuate the drop wire locators 7, causing the drop wire locators to move until a fallen drop wire is encountered, and indicators on the drop wire locators to indicate the position of the drop wire locator along the warp threads.
