Title:
紡績機又はワインダにおける無接触式の紡績糸監視のための方法及び装置
Document Type and Number:
Japanese Patent JP4750917
Kind Code:
B2
Abstract:
A yarn monitoring sensor (6) is subject to error due to transverse movement of yarn (3) in the sensing zone. The momentary position of the yarn is determined, e.g. according to the position of the traverse guide (9) of the wind-up, and a compensation related to its position is applied. The sensor can be an optical or capacitance sensor, acting as clearer and yarn monitor. The compensating values are determined by calibration with a test yarn using a sensor (18) in a region in the thread path where there is no transverse movement.
