Process and apparatus for detecting differences in yarn tensions

Abstract

Abstract 1. A method of detecting differences in filament traction in a bundle of parallel filaments in textile machines, particularly warping machines or warping frames, the individual filaments of the bundle of filaments being equidistant from one another in the measuring zone, characterised in that the bundle of filaments as a whole is deflected from its general plane under conditions which are the same for all the individual filaments, for example by means of filaments guide bars common to the filaments of the bundle, into a new plane of which the length is delimited by the measuring zone in the direction of travel and is returned after passing that measuring zone, and in that the individual filaments are deflected from the plane in a fixed sequence by a predetermined force in the vicinity of the measuring zone, the degree of deflection being measured and/or recorded and/or used as a correcting variable for regulating and/or control functions.
