    摘要: A method and mechanism for repairing warp thread breaks in a weaving loom in which a broken warp thread is detected by a fallen drop wire of a warp stop motion device, the method comprising: upon the falling of a drop wire, taking a new warp thread from a supply of warp thread separate from the loom supply of warp thread, and moving the new warp thread to a position between the warp stop motion device and the harness of the loom by a rethreading mechanism; raising the fallen drop wire and threading a first end of the new warp thread through the raised drop wire by the rethreading mechanism; and threading a second end of the new warp thread through a heddle of the harness corresponding to the broken warp thread.

    摘要: The location of a warp thread break in a weaving loom using electrically conductive drop wires bridging an electrode pair upon occurrence of a warp thread break includes applying opposing known voltages across opposite ends of the electrode pair, establishing current circuits including the voltage sources, the electrode pair and a fallen drop wire, and determining the distance between one end of the electrode pair and the fallen drop wire by calculations using known values corresponding with the voltages and measurements of values corresponding to the current values in the current circuits. A system for carrying out the method includes electrode pairs having a detectible resistance, conductive drop wires, voltage sources connected to the electrode pairs, current detecting/measuring devices, computerized calculating system, warp break location indicators and connecting circuit elements.
