ABSTRACT:
Method and apparatus for continuously monitoring a moving yarn line to detect the presence of undesired denier imperfections. The yarn is passed through an elongated constricted passage sensing device into which a sensing fluid is concurrently fed. The back pressure thus created in the fluid carrying line due to flow resistance in the sensing device, is monitored to detect variations which would indicate an imperfection in the moving yarn line.
