(54)	Improved device for measuring the mechanical tension of the yarn in weaving systems and the like

(57) The device comprises a couple of thread guide eyelets that are spaced on a rectilinear support (X) and a sensor (S) placed between said eyelets, external to the rectilinear support, under the pressure of the yarn running from one eyelet to the other, thereby defining two path segments reciprocally inclined at a predetermined angle (α). The thread guide eyelets (O'1-O'2) are inclined in opposite directions with respect to the rectilinear support (X), so that the yarn (F) passes diagonally through the eye of each thread guide eyelet; and the inclination of the eyelets with respect to the support (X) is chosen so that contact arises between the yarn and two points (C1-C2) of each eyelet, whereby the inclination of the path segments (T1-T2) of the yarn in the spans between the eyelets and the sensor (S') is kept constant.
