Yedynovych M. Investigation and development of contactless system of supervising and controlling of a weft skew in fabrics

Object of research: the fabric, as two-dimensional object which is deforming, systems of weft skew correcting. The purpose of research: creation contactless system of weft skew correcting, which is effective on fabrics of all kinds. The methods of optimal control, identification, analysis of interaction two-dimensional systems, electric devices, PC are used. The connection between the responses of the sensor for the deformed and not deformed fabric is investigated; the model of interaction of the fabric with the correct shaft is developed. It is developed the optimal system of weft skew correcting. The device for the control of anisotropy properties of the fabric and contactless sensor of a weft skew are created. It is investigated electrical anisotropy properties of the fabric. 4 systems of weft skew correcting are introduced at the Kherson cotton mills. Application field is textile and finishing industry.
