METHOD AND DEVICE FOR THE AUTOMATIC DETERMINATION OF THE AVERAGE FINENESS AND OF THE VARIATION COEFFICIENT OF THE FINENESS OF TEXTILE AND TECHNICAL THREADS, RIBBONS AND RIBBONS.

Abstract

Abstract Translated from French PROCEDE POUR LA DETERMINATION AUTOMATIQUE DE LA FINESSE MOYENNE ET DU COEFFICIENT DE VARIATION DE LA FINESSE DES FILS TEXTILES ET TECHNIQUES, DES BOUDINS ET DES RUBANS DANS AU MOINS UNE UNITE DE CONFECTION, CARACTERISE EN CE QUE CETTE DETERMINATION S'EFFECTUE DANS LA MEME OPERATION ET SUR LES MEMES ECHANTILLONS DE FIL, DE BOUDIN OU DE RUBAN QUE POUR UN CONTROLE D'UNIFORMITE NORMAL, LE SIGNAL DE MESURE OBTENU DANS L'ORGANE DE MESURE 2 DE L'APPAREIL DE CONTROLE 1 DE L'UNIFORMITE ETANT TRAITE DE TELLE MANIERE PAR UN CALCULATEUR 12 QUE CELUI-CI FOURNIT LA VALEUR MOYENNE DE LA FINESSE, DE MEME QUE LE COEFFICIENT DE VARIATION DE LA FINESSE DE SECTEURS DE CONTROLE DE FIL, DE BOUDIN OU DE RUBAN D'UNE LONGUEUR DETERMINEE. PROCESS FOR THE AUTOMATIC DETERMINATION OF THE AVERAGE THINNESS AND OF THE COEFFICIENT OF VARIATION OF THE THREADS OF TEXTILE AND TECHNICAL THREADS, BANDS AND RIBBONS IN AT LEAST ONE BUILDING UNIT, CHARACTERIZED IN THAT THIS DETERMINATION IS CARRIED OUT IN THE SAME OPERATION AND ON THE SAME SAMPLES OF WIRE, BLANK OR TAPE AS FOR A NORMAL UNIFORMITY CHECK, THE MEASUREMENT SIGNAL OBTAINED IN MEASURING ORGAN 2 OF UNIFORMITY TESTING APPARATUS 1 BE PROCESSED IN SUCH MANNER BY A CALCULATOR 12 THAT THIS PROVIDES THE AVERAGE FINESSE VALUE, AS WELL AS THE COEFFICIENT OF VARIATION OF THE FINESSE OF SECTORS OF CONTROL OF WIRE, BUCKLE OR TAPE OF A DETERMINED LENGTH.
