Abstract (en)

Provided with a device for sensing a snapped thread which includes a device for controlling yarn tension of a divided thread warper for providing an appropriate tension before and after dividing threads, and a device for guiding the divided thread of a divided thread warper for sensing immediately a fact that some pieces of the divided threads are snapped off and stopping the operations of a yarn feeding section(20) and a winding section(40), thereby making the division of threads without difficulties and preventing potential defects that may occur during a process for weaving the wound threads. <IMAGE>
