Abstract
A method for monitoring warp thread breaks on weaving machines includes the steps of locating broken warp threads and storing the number of broken warp threads in a memory as a function of the postions of the breaks.
Claims5
A method for monitoring warp thread breaks on a weaving machine, comprising the steps of:
- upon the occurrence of a broken warp thread, locating the position of the broken warp thread relative to the weaving width of the weaving machine;
- generating a signal which is indicative of each warp thread break and the position of said break relative to said weaving width;
- passing each of said signals to a memory signal storing means;
- processing said signals in said storing means to make intelligible to an operator of the machine the number of occurrences of thread breaks as a function of their position relative to said weaving width.

A device for monitoring warp thread breaks on a weaving machine of the type in which warp thread breaks are detected by means of a warp stop motion including drop wires associated with the warp threads, comprising:
- warp thread break locating means for locating the position of the fallen drop wires relative to the weaving width of the weaving machine;
- signal generating means for generating signals indicative of the occurrence of a fallen drop wire and the position at which said break locating means detects the fallen drop wires on each occurrence of a warp thread break;
- memory signal storing means arranged to receive said signals;
- and
- signal processing means connected to the memory signal storing means for processing said signals and making intelligible to an operator of the machine the number of warp thread break occurrences as a function of their position relative to said weaving width.
