摘要:
Herein disclosed is a method of and an apparatus for marking a woven fabric with indicia of discrete events of a predetermined nature or natures such as unit lengths of the fabric woven and the occurrences of defects in weaving such as improperly inserted picks of weft yarn, wherein picks of an index yarn or yarns are inserted into the weft-filling shed of the warp yarns concurrently with insertion of picks of the weft yarn when the occurrences of events of the predetermined nature or natures are detected during weaving of the fabric, the natures of the events being distinguished from one another by the difference between the lengths, colors, numbers or any other characteristics of the picks of the index yarn inwoven into the fabric.
摘要:
A process for automated monitoring of faults occurring in textile webs. At least one marking is worked into the web under manufacture. The marking permits incremental measurement of the textile web and facilitates the determination of particular positions thereon. Web faults and other events are detected during manufacture and their positions stored electronically. Detected faults can then be efficiently located and examined using the electronically stored location coordinates and the marking. Since the marking is worked into the web, the location of the fault can be efficiently determined even at later stages in the manufacturing process.
