Apparatus monitoring and/or adjusting tensile force in a yarn ( 10 ) including at least three consecutive yarn deflecting elements ( 11, 12, 13 ) of which the central deflecting element ( 12 ) is displaceably held by a retention device ( 14 ) that is supported in such a way that the motion and/or position of the deflecting element ( 12 ) is substantially a function only of the tensile force F1 in one yarn segment, such segment being situated between the displaceable deflecting element ( 12 ) and only one of the two neighboring deflecting elements ( 11 or 13 ).
