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.
Claims13
An apparatus for electrically detecting and locating a broken warp thread in a weaving loom including a plurality of drop wires arranged to be associated with the warp threads of a loom so that, upon loss of tension in a warp thread due to breakage a drop wire drops from a normal high to a low position, comprising:
- means for generating a broken warp electrical signal when a drop wire drops to a low position;
- a movable drop wire locator arranged to traverse a locator path adjacent said drop wires;
- means for moving said locator along its locator path in response to said broken warp electrical signal;
- means associated with the locator for detecting and indicating the position of the drop wire.
