Abstract

Système dérouleur de bande. Un entraînement de cabestan excite un galet formant cabestan et commande le mouvement de la bande, et des servosystèmes de bobines excitent les bobines pour maintenir les bras tendeurs en positions angulaires centrales nominales. Les variations de tension de bande avec le diamètre des rouleaux des bobines sont réduites au minimum et autocompensées par orientation des positions des bras perpendiculairement à la direction de la bande pour des diamètres intermédiaires des rouleaux. Des transducteurs de couple contrôlent le couple des bras tendeurs selon les conditions de fonctionnement. Application aux dérouleurs professionnels de bandes magnétiques acoustiques.
