Method for detecting a found yarn end
摘要:
A found yarn end at a predetermined position of a spinning bobbin is detected after completion of a yarn end finding operation, whereby discrimination between success and failure in yarn end finding is made through detection of the presence or absence of the found yarn end after the actual yarn end finding treatment.
