  • the present invention relates to a device for finding and catching silk cocoon thread ends, and especially a device for finding and catching silk cocoon thread ends and providing the thread ends to a dirt removing and transportation unit and to thread processing units, for producing silk yarns from the cocoon threads.
  • Silk yarns are produced from silk cocoons. During the production silk cocoons are boiled, filled with water, a cocoon thread end is recognized and caught, the silk thread is unreeled and combined with other threads to form a silk yarn. Cocoon thread ends are detected by workers that have to search for a cocoon thread end and to catch that end by forceps. A cocoon thread is very thin and it is usually hard to detect. The detection is executed after the cocoons are boiled, and the workers usually work in a relatively hot environment that decreased their efficiency.
  • This prior art method has several drawbacks: it is labor and power consuming, many cocoons are damaged during the stage of finding and catching a cocoon thread end and only up to 70% of a cocoon thread was exploited.
