Title
(EN) PROCESS AND DEVICE FOR MEASURING THE TORSION OF A MOVING ELONGATED TEST OBJECT
(FR) PROCEDE ET DISPOSITIF DE MESURE DE LA TORSION D'UN ECHANTILLON ALLONGE EN MOUVEMENT
Abstract
(EN) The test object (G) is illuminated obliquely to its direction of motion (P) by at least one light source (L, L') and the reflected light (R) is directed through an aperture (2) to a photoreceptor (3). The photoreceptor signal is tested in an evaluation unit for periodicities due to irregularities of the test object (G) caused by torsion, the wavelength of the periodicities serving as a measure of the torsion. Rapid and accurate measurement of the torsion of yarns is thereby achieved.
(FR) Un échantillon (G) est éclairé obliquement par rapport à son sens de déplacement (P) au moyen d'au moins une source de lumière (L, L'), et la lumière réfléchie (R) est reproduite sur un diaphragme (2) et fournie à un photorécepteur (3). Les signaux de celui-ci sont examinés par une unité d'évaluation (4) afin de détecter des périodicités dues à des irrégularités de l'échantillon (G) provoquées par la torsion, la longueur d'onde de ces périodicités représentant une valeur de mesure de la torsion. On peut ainsi mesurer de manière rapide et précise la torsion de fils.
