Embodiment Construction

[0038] figure 1 A tensiometer T is schematically depicted for any kind of yarn processing to measure the force exerted by the yarn Y on the bending element 1 of the tensiometer T, that is to say at a silent standstill or while running Tension of yarn Y. exist figure 1 , the bending element 1 is deflected downwards by the force exerted by the contacting yarn Y (the double arrow R indicates the induced vibratory movement). The bending element 1 is, for example, a narrow plate-like arm made of a relatively "hard" (blunt) material, preferably a wear-resistant material, more preferably a ceramic such as aluminum oxide, while There are no bending sensitive / responsive means eg in the form of piezoresistors (placed directly on the arm as with known means), strain gauges etc.

[0039] The bending element 1 is preferably of square section, is fixed by supports 3 , 4 and has a free end 2 . Yarn Y is skewed at the free end for 2 turns. On the lower side 5 of the curved part 1 a dampi...

Abstract

Tensiometer for measuring the force imparted by a yarn on a bending element (1) which is secured in a fixation (3), having a unitary oscillation-damping element (D) made of an intrinsically damping material like rubber or an elastomer, the unitary damping element comprising a base body (6) secured to the bending element (1) and at least one oscillation body (8) which can oscillate, at least substantially in the direction of the deflection of the bending element, in relation to the base body and to the bending element, and further having an energy dissipation zone (7) between the base body (6)and the oscillation body (8).

Description

technical field [0001] The invention relates to a yarn tensiometer for measuring the force of a yarn acting on a bending element. Background technique [0002] In particular, with the yarn running, the bending element vibrates as the tensiometer measures the force exerted by the yarn. This vibration affects the accurate reading of force or yarn tension. The damping elements fastened to the bending elements must therefore dampen the vibrations within defined, desired ranges. [0003] The tensiometer known from EP0475001A has a strip of foam glued to the side of the bending element in order to dampen the vibrations of the bending element. [0004] The tensiometer known from DE9000443U has a damping element made of fluororubber, which is fixed on the bending element by means of joints that engage into longitudinal grooves of the bending element in order to adjust the damping element in the longitudinal direction position and damping effect. [0005] The tensiometer known fr...
