Title (EN) METHOD AND APPARATUS FOR MEASURING AND INDICATING THE WINDING STAGE OF A TAPE
(FR) PROCEDE ET DISPOSITIF POUR LA MESURE ET L"AFFICHAGE DE L"ETAT D"ENROULEMENT D"UNE BANDE
Abstract: front page image
(EN)In a magnetic tape apparatus, the impulses derived from the rotations of a spool (1) are counted in order to display (14) the winding stage of the tape. The ratio of the number of revolutions (12) of spools (1, 2) to that of the total winding (11) is determined by means of a trial run. The counting procedure (12) is linearized (13) by means of these values.
(FR)Dans un appareil a bande magnetique, on compte des impulsions derivees des rotations d"une bobine (1) pour afficher (14) l"etat de la bande. On determine le rapport du nombre de tours (12) des bobines (1, 2) a celui de l"enroulement total (11) au moyen d"une course d"essai. On linearise (13) le processus de comptage (12) avec ces valeurs.
