Apparatus for measuring the weft thread position and for aligning the weft thread in textiles

摘要: The invention is a mechanical method for measuring the position of weft thread in moving textile fabric and aligning thread. also an apparatus carrying out method. comprises introducing substantially at points, tension (in direction thread) to scan least two places forces that appear therefrom determine draft angle. emcompasses stretching sheet with increasing force travel over follower device propelling/dragging on determining angle from those measurements.
